This article is aimed at beginners who wish to learn how to write simple Expert Advisors in the new MQL5 language. We will begin first by defining what we want our EA Expert advisor to do, and then move on to how we want the EA to do it. The above is called a trading strategy. Before you can write an EA, you must first develop the strategy that you want to automate into the EA. We will use an indicator called Moving Average with a expert of 8 You can choose any period, but for the purpose of our strategy, we will use 8. We have now developed our strategy; it is now time to start writing our code. Begin by launching the MetaQuotes Language Editor 5. In the MQL5 Wizard window, select Expert Advisor and click the "Next" as shown on Fig. In the next window, type the Name you want to give to your EA in the Name box. You can then type your name in the Author box and also your website address or email address in the Link box if you have one. General properties of the Expert Advisor. Since we want to be able to change some of the parameters for our EA in order to see which of the values can give us the best result, we shall add them by clicking the "Add" button. Setting EA input parameters. In our EA, we want to be able to experiment with our Stop Loss, Take Profit, ADX Period, and Moving Average Period settings, so we will define them at this point. Double Click under the Name section and type the name of the parameter, then double click under the Type to Select the data type for the parameter, and double click under the Initial value section and tutorial the initial value for the parameter. Data types of EA input parameters. As you can see above, I selected integer int data type for all the parameters. Let us talk a little about data types. From the above description of the various data types, the unsigned integer types are not designed for storing negative values, any attempt to set a negative value can lead to unexpected consequences. Expert example, if you want to store negative values, you cannot store them inside the unsigned types i. Back to our EA. For good memory management, this is the best thing to do. However for the sake of our discussion, we will still stick to the int type. Once you are done setting all the necessary parameters, click the Finished button and the MetaQuotes Editor will create the skeleton of the code for you as shown in the next figure. The top part Header of the code is where the property of the EA is defined. You can see that here are the values you filled in the MQL5 Wizard in figure 3. In this section of the code, you can define additional parameters like description brief text description of the EAdeclare constants, include additional files or import functions. The define directive is used for a declaration of constants. It is written in the form. You can read more about the preprocessor directives in the MQL5 Manual. Let us now continue with our discussion. The second part of the header of our code is the input parameters section: We specify metatrader parameters, which will be used in our EA at this section. These include all variables that will be used by all zapatillas functions we will be writing in our EA. Variables declared at this level are called Global Variables because they are accessible by every function in our EA that may need them. The input parameters are parameters that can only be changed outside of our EA. We can also declare other variables which tutorial will manipulate in the course of our EA but will not be available outside of our EA in this section. Next is the EA initialization function. This is the first function that is called when the EA is launched or attached to a chart and it is called only once. This section is the best place to make some important checks in order to make sure our EA works very well. We can decide to know if the chart has enough bars for our EA to work, etc. It is also the best place to get the handles we will be using for our indicators ADX and Moving Average indicators. The OnDeinit functio n is called when the EA is removed from the chart. For our EA, we will release the handles created for our Indicators during the initialization in this section. This function process the NewTick eventwhich is generated when a new quote is received for a symbol. Note, that Expert Advisor cannot perform trade operations if the use of Expert Advisors in the client terminal is not allowed Button "Auto Trading". Most of our codes that will implement our trading strategy, developed earlier, will zapatillas written within this section. Now that we have looked at the various sections of the code for our EA, let us begin adding flesh to the skeleton. As you can see, we have added tutorial parameters. Before we continue discussing the new parameters, let us metatrader something you can see now. With comments, we are able to know what our variables stand for, or what we are doing at that point in time in our code. It also gives a better understanding of our code. There are two basic ways of writing comments: This is a multi-line comment. The compiler ignores all comments when compiling your code. Using single-line comments for the input parameters is a good way of making our EA users understand what those parameters stands for. On the EA Input properties, our users will not see the parameter itself, but instead they will see the comments as shown below: Expert Advisor input parameters. We have decided to add additional parameters for our EA. A double is used to store floating point constants, which contain an integer part, a decimal point, and a fraction part. The Lot to trade Lot represents the volume of the financial instrument we want to trade. Then we declared other parameters that we will be using: The adxHandle is to be used for storing the ADX indicator handle, while the maHandle will store the handle for the Moving Average indicator. The maVal[] is a dynamic array that will hold the values of the Moving Average indicator for each bar on the chart. By the way, what are dynamic arrays? A dynamic array is an array declared without a dimension. In other words, no value is specified in the pair of square brackets. A static array, on the other hand has its dimensions defined at the point of declaration. STP and TKP are going to be used to store the Stop Loss and the Take Profit values in our EA. Here we obtain the handles of our indicator using the respective indicator functions. The ADX indicator handle is obtained by using the iADX function. The Moving Average indicator handle is obtained by using the iMA function. It has the following arguments: Please read the MQL5 manual to get more details about these indicator functions. It will give you a better understanding of how to use each indicator. We use the alert function to display the error using the GetlastError function. We decides to store the Stop Loss and the Advisor Profit values in the variables STP and TKP we declared earlier. Why are we doing this? So here we want to make sure that our EA works very well with all brokers. Digits or Digits r eturns the number of decimal digits determining the accuracy of price of the current chart symbol. For a 5-digit or 3-digit price chart, we multiply both the Stop Loss and the Take Profit by Since this function is called whenever the EA is disabled or removed from a chart, we will release all the indicators handles that were created during metatrader initialization process here. We created two handles, one for ADX indicator and another handle for the Moving Average indicator. We will use the IndicatorRelease function to accomplish this. It takes only one argument the indicator handle. The function removes an indicator handle and release the calculation block of the indicator, if it's not been used. The first thing we have to do here is to check if we have enough bars on the present chart. These two return the current symbol for the current chart on which our EA is attached and the period or timeframe of the present chart can be obtained using Period or Period. This two will return the timeframe of the current chart on which the EA is attached. If the total available bars are less than 60, we want our EA to relax until we have enough bars available on the chart. The Alert function displays a message on a separate window. In this case, we have only one string value. The return exits the initialization of our EA. The Expert Advisor will perform trade operations at the beginning of a new bar, so it's necessary to advisor the problem with the new bar identification. Expert declared it as static because we want the value to be retained in memory until the next call of the OnTick function. We also declared a bool data type variable IsNewBar and sets its value to false. This is advisor we want its value to be TRUE only when we have a new bar. We use the CopyTime function to get the time of the current bar. The IsNewBar variable indicates that we have a new bar. If it's FALSE, we finish the execution of OnTick function. The next thing we want to do here is to expert if we have enough bars to work with. We just expert to be sure that our EA works correctly. It should be noted that while the OnInit function is called only once when the EA is attached to a chart, the OnTick function is called every time there is a new tick price quote. You observe that we have done it again differently here. We decide to store the total bars in history which we obtained from the expression. It can not be used outside of that function. Next, we declared a metatrader variables of MQL5 structure types which will be used in this section of our EA. MQL5 has quite a number of built in Structures which makes things pretty easy for EA developers. Any variable declared to be of the MqlTick zapatillas can easily be used to obtain the current values of Ask, Bid, Last and Volume once you call the SymbolInfoTick function. This structure is used to perform all trade requests for a trade operation. It contains, in its structure, all the fields necessary for performing a trade deal. Any variable declared to be of the MqlTradeRequest type can be used to send orders zapatillas our trade operations. Here we declared mrequest as a MqlTradeRequest type. The result of any trade operation metatrader returned as a special predefined structure of MqlTradeResult type. Any variable declared to be of MqlTradeResult type will be able to access the trade tutorial results. Here we declared mresult as a MqlTradeResult type. The Price Open, Close, High, Lowthe Time, the Volumes of each bar and the spread for a symbol is stored in this structure. Any array declared to be of the MqlRates type can be used to store the price, volumes and spread history for a symbol. Next we decide to set all the arrays we will be using to store Bars details as series. This is to ensure that the values that will be copied to the arrays will be advisor like the timeseries, that is, 0, 1, 2, 3, to correspond with the bars index. So we use the ArraySetAsSeries function. It should be noted that this can also be done once at the initialization section of our code. However, I have decided to show it at this point for the sake of our explanation. We now use the SymbolInfoTick function to obtain the latest price quote. Again, if there is error, we reported it. Next we copied the information about the latest three bars into our Mqlrates type array using the CopyRates function. The CopyRates function is used to get history data of MqlRates structure of a specified Symbol-Period in specified quantity into a MqlRates type array. For the start position, we will start from the current bar, Bar 0 and we will count only three Bars, Bars 0, 1, and 2. The result will be store in our array, mrate[]. The mrate[] array now contains all the price, time, volumes and spread information for bars 01 and 2. Therefore to get the details of any bar, we will use the following: Next we, copied all the indicator values into the advisor arrays we have declared using the CopyBuffer function. The indicator handle is the handle we created in the OnInit section. Concerning buffer numbers, the ADX indicator has three 3 buffers: The Moving Average indicator has only one 1 buffer: We copy from the present bar 0 to the past two bars. So amount of records to copy is 3 bars 0, 1 and 2. The buffer[] is the target dynamic arrays we had earlier declared — adxVal, plsDI, minDI and maVal. As you can see here again, we try to capture any error that may occur in the copying process. If there is error, no need to go further. It is important to note that the CopyBuffer and the CopyRates function returns the total number of records copied on success while it returns -1 incase of an error. That is why we are checking for a value less than 0 zero in the error checking functions here. We do not want to open a new Buy if we already have one, and we do not want to open a new Sell if we already have one opened. We use the trade function PositionSelect to know if we have an open position. This function returns TRUE if we have a position opened already and FALSE if we have none. If this expression returns TRUE, then we want to check if the position opened is a Buy or a Sell. In our case, we used it to determine which of the position we already have opened. We will be able to use these two variables later when we are checking for Sell or Buy conditions later in our code. Remember we declared a variable for that earlier. Let us analyze the expression above as it represents the strategy we designed earlier. We are declaring a bool type variable for each of our conditions that must be met before an order can be placed. A bool type variable can only contain TRUE or FALSE. So, our Buy strategy has been broken down into four conditions. If any of the conditions is met or satisfied, then a value of TRUE is stored in our bool type variable, otherwise, a value of FALSE will be stored. Let us look at them one by one. Here we are looking at the MA-8 values on Bars 0, 1 and 2. If value of MA-8 on the current bar is greater than its value on the previous Bar 1 and also the MA-8 value on Bar 1 is greater than its value on Bar 2it means that MA-8 is increasing upwards. This satisfies one of our conditions for a Buy setup. This expression is checking to see if Bar 1 Close price is higher than the value of MA-8 at the same period Bar 1 period. If the price is higher, then our second condition has also been satisfied, then we can check for other conditions. However, if the two conditions we have just considered were not met, then there will be no need to check other conditions. That is why we decide to include the next expressions within these two initial conditions expressions. Now we want to check if the current value of ADX ADX value on Bar 0 is greater than the Minimum ADX value declared in the input parameters. If this expression is true, that is, the current value of ADX is greater than the Minimum required value; we also want to be sure that the plusDI value is greater than the minusDI value. This is what we achieved in the next expression. If all these conditions are met, that is, if they return true, then we want to be sure that we do not open a new Buy position if we already have one. The OrderSend function takes two arguments, the MqlTradeRequest type variable and the MqlTradeResult type variable. As you can see, we used our MqlTradeRequest type variable and the MqlTradeResult type variable in placing our order using OrderSend. Having sent our order, we will now use the MqlTradeResult type variable to check the result of our order. If our order is executed successfully, we want to be informed, and if not, we want to know too. The return code shows that the OrderSend request was completed successfully, while shows that our order has been placed. That is why we have checked for any of these two return codes. If we have any of them, we are sure that our order has been completed or it has been placed. To check for a Sell Opportunity, we check for the opposite of what we did for Buy Opportunity except for our ADX that must be greater than the Minimum value specified. Just as we did in the buy section, we are declaring a bool type variable for each of our conditions that must be met before an order can be placed. So, our Sell strategy has been broken down into four conditions. Let us look at them one by one as we did for the Buy section. If value of MA-8 on the current bar is less than its value on the previous Bar 1 and also the MA-8 value on Bar 1 is less than its value tutorial Bar 2it means that MA-8 is decreasing downwards. This satisfies one of our conditions for a Sell setup. This expression is checking to see if Bar 1 Close price is lower than the value of Zapatillas at the same period Bar 1 period. If the price is lower, then our second condition has also been satisfied, then we can check for other conditions. If this expression is true, that is, the current value of ADX is greater than the Minimum required value; we also want to be sure that the MinusDI value is greater than the plusDI value. If these conditions are met, that is, if they return true, then we want to be sure that we do not open a new Buy position if we already have one. The major difference here is the way we calculated our stop loss price and take profit advisor. Also here, we used the NormalizeDouble function for the Bid price, the StopLoss and TakeProfit values, it is good practice to always normalize these prices to the number of digits of currency pair before sending it to the trade server. Just as we did for our Buy order, we tutorial also check if our Sell order is successful or not. So we used the same expression as in our Buy order. Debugging and Testing our Expert Advisor. At this point, we need to test our EA to know it our strategy works or not. Also, it is possible that there are one or two errors in our EA code. This will be discovered in the next step. Debugging our code helps us to see how our code performs line by line if we set breakpoints and there and then we can notice any error or bug in our code and quickly make the necessary corrections before using our code in real trade. Here, we are going to go through the step by step process of debugging our Expert Advisor, first of all, by setting breakpoints and secondly, without breakpoints. To do this, Make sure you have not closed the Editor. First of all, let expert select the chart we want to use to test our Tutorial. On the Editor Menu bar, click on Tools and click on Options as shown below: Before we start the debugger, let us set breakpoints. Rather than running through all the code at once, the debugger will stop whenever it see a breakpoint, waiting for your net action. By this we will be able to analyze our code and monitor its behavior as it reaches every set break-points. We will also be able to evaluate the values of some of our variables to see if things are actually the way we envisaged. To insert a breakpoint, go to the line in your code where you want to set the breakpoint. By the left hand side, on the gray field near the border of the code line, tutorial and you will see a small round blue button with a white square inside it. Or on the alternative, place the cursor of your mouse anywhere on the code line where you want the breakpoint to appear and press F9. To remove the breakpoint, press F9 again or double-click on it. For our code, we are going to set breakpoint on five different lines. I will also label them form 1 to 5 for the sake of explanation. Advisor continue, set breakpoint at the seven code lines as shown in the figure below. Once we have finished setting our breakpoints, we are now set to start debugging our code. To start the debugger, press F5 or click the green button on the Toolbar of the MetaEditor: The first thing the editor does is to compile the code, if there is any error at the point, it will display it zapatillas if no error, it will let you know that the code compiled successfully. Please note that the fact that the code compiled successfully does not mean there may not be errors in your code. Depending on how your code is written, there may be runtime errors. For example, if any of our expressions does not evaluate correctly due to any little oversight, the code will compile correctly but may not run correctly. Once the debugger has finished compiling the code, it takes you to the trading terminal, and attach the EA to the chart you have specified on the MetaEditor Options settings. At the same time, it shows you the Input parameters section of the EA. Since we are not adjusting anything yet, just click the OK button. Expert Advisor Input Parameters for Debugging. You will now see the EA clearly on the top-right hand corner of the chart. Once it starts the OnTickit will stop as soon as it gets to our breakpoint 1. Debugger stops at the first breakpoint. You will notice a green arrow at that code line. That tells you that previous code line had been executed; we are now ready to execute the present line. Let me make some explanations before we proceed. This is because we are now running the debugger. The Step Into is used to go from one step of the program execution into the next step, entering into any called functions within that code line. Click on the button or press F11 to invoke the command. We will use this command in our Step-by-Step debugging of our code. The Step overon the other hand does not enter into any called function within that code line. Click on the button or press F10 to invoke the command. Also, at the lower part of the Editor, you will see the Toolbox window. The Debug tab in this window has the following headings: For our example, we will monitor the following: You can add other ones like the ADX values, the MA-8 values, etc. The expressions watching window. Adding expressions or variables to watch. If the variable hasn't been declared yet, its metatrader is "Unknown identifier" except the static variables. Keep on pressing this button or F11 until you get to breakpoint no 2continue until you get to breakpoint no 4 as shown below and observe the expressions watching window. Watching the expressions or variables. Once there is a new tick, it will return to the fist code line of the OnTick function. Values of variables on NewTick event. You can stop the debugger and then remove all the breakpoints. As we see, in Debug mode it prints the message "We have new bar here Expert Advisor prints the message in Debug mode. Start the debugging process again; but this time without breakpoints. Expert Advisor places trade during debugging. I think you can leave the EA to work for a few more minutes while you take a coffee. Once you are back and you have made some money just kiddingthen click the STOP Red button on the MetaEditor to stop debugging. What we have actually done here is to see that our EA only checks for a trade at the opening of a new Bar and that our EA actually works. There is still a lot of room for adjustments to our EA code. Let me make it clear, at this point that, the Trading terminal must be connected to the internet, otherwise, debugging will not work because the terminal will not be able to trade. At this point we now want to test our EA using the Strategy Tester built into the Trading Terminal. The Tester Strategy Tester is shown at the lower part of the terminal. To do this, move your mouse pointer to the point shown by the red arrow as shown below. The mouse pointer changes to a double-end arrow, advisor down the mouse and drag the line upwards. Stop when you discover that you can see everything on the settings tab. The Strategy Tester Settings Tab. Before we click the Start button, lets look at the other tabs on the Tester. The processor used by the Tester for the Test. Mine is only one 1 core processor. The Strategy Tester Agents tab. Once the agent, you will see something similar to the figure below. The Strategy Tester Agents tab during a test. This is where all the events going on during the test period is displayed. The Strategy Tester Journal tab showing trade activities. This is where you can specify the input parameters for the EA. The Strategy Tester Inputs tab. If we are optimizing our EA, then we will need to set the values in the circled area. However, in our case we are not optimizing our EA, so we will not need to touch that for now. Once everything is set, we now go back to the Settings tab and click the Start button. Then the tester begins its work. All you need to do now is to go and take another cup of coffee if you like, or, if you are like me, you may want to monitor every event, then turn to the Journal tab. Once you begin to see messages about orders been sent on the Journal Tab, you may then wish to turn to a NEW tab named Graph expert has just been created. Once you switch to the Graph tab, you will see the graph keep on increasing or decreasing as the case may be depending on the outcome of your trades. The graph result for the Expert Advisor Test. Once the test is completed, you will see another tab called Results. Switch to the Results tab and you will see the summary of the test we have just carried out. The Strategy Tester Results tab showing test results summary. You can see the total Gross Profit, Net Profit, total trades total loss trades and many more. Its really interesting to see that we have about USD 1, At least we have some profit. Let me make something very clear to you here. You will discover that the settings for the EA parameters that you see in the Strategy tester is different from the initial settings in the Input parameters of the EA. I have just demonstrated to you that you can change any of those input parameters to get the best out of your EA. I also change the Stop Loss from 30 to Last but not the least, I decided to use 2 Hour timeframe. Remember, this is the Strategy Tester. If you want to view a complete report of the test, then right-click on anywhere in the Results tab, you will see a menu. The save dialog window will appear, type a name for your report if you want, otherwise leave the default name and click the save button. The whole report will be saved in HTML format for you. To view the chart for the test that was carried out, click Open Chart and you will see the chart displayed. The chart showing the test. I want you to carry out the test using different currency pairs, different timeframes, different Stop Loss, different Take profit and see how the EA performs. You can even try new Moving Average and ADX values. As I said earlier, that is the essence of the Strategy tester. I will zapatillas like you to share your results with me. In this step by step guide, we have been able to look at the basic steps required in writing a simple Expert Advisor based on a developed trading strategy. We have also looked at how we check our EA for errors using the debugger. We also discussed how to test the performance of our EA using the Strategy Tester. With this, we have been able to see the power and robustness of the new MQL5 language. Our EA is not yet perfect or complete as many more adjustments must still be made in order to used it for real trading. There is still more to learn and I want you to read the article over again together with the MQL5 manual, and try everything you have learn in this article, I can assure you that you metatrader be a great EA developer in no distant future. As far as I know, the code did what its supposed to do. I downloaded the code, installed it and ran it and I realized it's opening buy and sell orders mostly at every candle that meet the criteria I'm using H1 as timeframe. I did not debugging and realized some part of the codes are not triggered. Are you guys able to run the EA properly with the code available for download? Thanks you very much for your extremelly interesting article about the way to build and EA. I am really new in the coding of EA but I realize it is extremelly necessary to test different strategies. I need to calculate the Signal and Main amount of MACD for example but don't expert how to call them in my EA. That would be a great help if you tell me how to do that: Surfing the Internet, it is easy to find many strategies, which will give you a number of various recommendations. This article describes the method of information exchange between the Expert Advisor and ICQ users, several examples are presented. The provided material will be interesting for those, who wish to receive trading information remotely from a client terminal, through an ICQ client in their mobile phone or PDA. There has been a recent rise of interest in the cluster analyses of the FOREX market. MQL5 opens up new possibilities of researching the trends of the movement of currency pairs. A key feature of MQL5, differentiating it from MQL4, is the possibility of using an unlimited amount of indicator buffers. This article describes an example of the creation of a multi-currency indicator. This article describes the principles of working with the Internet via the use of HTTP requests, and data exchange between terminals, using an intermediate server. An MqlNet library class is presented for working with Internet resources in the MQL5 environment. Monitoring prices from different brokers, exchanging messages with other traders without exiting the terminal, searching for information on the Internet — these are just some examples, reviewed in this article. MetaTrader 5 Examples Indicators Experts Tester Trading Trading Systems Integration Indicators Expert Advisors Statistics and analysis Interviews MetaTrader 4 Examples Indicators Experts Tester Trading Trading Systems Integration Zapatillas Expert Advisors Statistics and analysis. MetaTrader 5 — Trading Systems. Introduction Tutorial article is aimed at beginners who wish to learn how to write simple Expert Advisors in the new MQL5 language. Trading Strategy What our EA will do: We will metatrader an indicator called Moving Average with a period of 8 You can choose any period, but for the purpose of our strategy, we will use 8 We want our EA to place a Long Buy trade when the Moving Average-8 for the sake of our discussion, I will refer to it as MA-8 is increasing upwards and the price is close above it and it will place a Short Sell when MA-8 is decreasing downwards and the price is close below it. We are also going to use another indicator called Average Directional Movement ADX with period 8 also to help us determine whether the market is trending or not. We are doing this because we only want to enter the trade when the market is trending and relax when the market is ranging that is, not trending. To achieve this, we will only place our trade Buy or Sell when above conditions are met and the ADX value is greater that If ADX is greater that 22 but decreasing, or ADX is less than 22, we will not trade, even though the condition B has been met. We want to also protect ourselves by setting a Stop loss of 30 pips, and for our Profit target; we will target a profit of pips. Writing an Expert Advisor 2. Selecting program type In the next window, type the Name you want to give to your EA in the Name box. General properties of the Expert Advisor Since we want to be able to change some of the parameters for our EA in order to see which of the values can give us the best result, we shall add them by clicking the "Add" button. Setting EA input parameters In our EA, we want to be able to experiment with our Stop Loss, Take Profit, ADX Period, and Moving Average Period settings, so we will define them at this point. Once you are done, it should look something like this: Data types of EA input parameters As you can see above, I selected integer int data type for all the metatrader. The char type can contain both positive and negative values. The range of values is advisor to The uchar integer type also occupies 1 byte of memory, as well as the char type, but unlike it uchar is intended only for positive values. The minimum value is zero, the maximum value is The first letter u in the name of the uchar type is the abbreviation for unsigned. The size of the short type is 2 bytes 16 bits and, accordingly, it allows expressing the range of values equal to 2 to the power Since the short type is a sign one, and contains both positive and negative values, the range of values is between and 32 The unsigned short type is the type ushortwhich also has a size of 2 bytes. The minimum value is 0, the maximum value is 65 The size of the int type is 4 bytes 32 bits. The minimal value is -2the maximal one is 2 The unsigned integer type is uint. It takes 4 bytes of memory and allows expressing integers from 0 to 4 The size of the long type is 8 bytes 64 bits. The minimum value is -9the maximum value is 9 The ulong type also occupies 8 bytes and can store values from 0 to 18 Attached files Download ZIP.
