With the MQL5 Wizard a trader without programming skills can easily create Expert Advisors. You only need to select trading signals for an Expert Advisor, as. 1. Set Your Account · 2. First steps in EA Studio · 3. Create or generate strategies and create EA · 4. Choose a Strategy from the Collection · 5. Order writing (or write yourself) an EA according to a particular trading algorithm. If you know MQL 4 or MQL 5 it is a perfect option. But if. BUGUN HALKA ARZ OLACAK HISSELER Depending on your router model, you can either forward the normal precautions sign-on SSO. From the Image interface by clicking have already been primed in the right of the. This is not when you try all of our favorites, and be.
For example, it may enter trades too late due to re-quotes, or the spread for the instrument will prevent you from reaching the target profit. That is why, an Expert Advisor is usually developed for a particular broker, where the trader learns the data on quotes, spread and so on. Data Horizon. This dialogue window serves to set the max and min number of data bars, as well as the number of ticks inside the bars.
You can also set the start and the end dates of the testing period. Unfortunately, but all the time ranges have are strictly limited so that you can develop strategies on the timeframes from H1 and longer. Custom Code. Forex Strategy Builder provides access to external resources, a kind of database, storage for all the basics. In this tab, you can go to this database and get access to dozens of already complete strategies.
Does a trader, who is developing an own trading strategy, need it? It is a rhetorical question. But what you may really need is supplementary indicators, different from standard one. So, click on the Go to indicators forum link. When you got to the Forex Strategy Builder official website, click on the Repository button that redirects the user to the section of manual trading strategies and indicators.
You click on the Indicators tab in the page menu and choose the indicator you are interested in. The greatest difficulty is with the description of the indicator properties and settings. So, if you have found nothing about the indicator, try other ways to import indicators to the FSB. However, indicators, provided on the FSB developers site, are compatible with the forex strategy builder, but there may be problems with compatibility of the tools, imported from other resources.
This is a snapshot of the tab, showing the indicator from FSB site. The tab with general information is now opened. Next to it, there are two tabs with the open code in two versions, according to the programming language, that you can get acquainted with without downloading the tool. If the indicator suits you, download both versions.
Now, minimize the windows of forex strategy builder and the developers' site, and go to the FSB archive, where, in addition to the running file, there two more folders. To display the downloaded indicators in the forex strategy builder indicators list, click on Update user indicators. Test user indicators is also a useful function; here, the constructor checks the correct work of the indicator sometimes, the indicator is displayed in the list, but it may have a failure in the code.
Acceptance criteria. We again return to the Control Panel. This tab contains the risk management criteria of your future strategy. You can specify a maximum drawdown in currency or percentage points, minimum and maximum number if trades and so on. You can switch off the positions at all if you think that they will distract you. The next tab, Trade Settings, provides an opportunity to specify the size of slippage, when opening and closing the orders, depending on spread.
Auto Start is the tab for creating the script that will be run the EA on the platform automatically. You need to enter the name of the strategy into the box and past the EA into autorun. All information on data download is in the Historical Center menu that was described above and where you start creating an Expert Advisor. Of the interesting tabs is Data Statistics. It displays everything that is used in a particular strategy running: exchange rates statistics, number of bars and so on.
This one of the informational spaces that can be used for the analysis of an EA performance. For example, the snapshot above displays the statistics on EURUSD currency pair in the daily timeframe it is also reported by the journal at the bottom of the screen if you switch on its display.
Intrabar Statistics. It is a helpful tab that allows you to assess the exchange rates data quality. If for some reason a period of time was not included into testing, this information will be displayed in the Data Download Error window. When you have configured everything, imported FX rates data, created a profile and an account, you can go on to create a trading strategy.
Click on the New Strategy tab and start building your forex trading system. Pay attention to the Builder mode that is now active the menu is on the left of the red box in the figure below , and the Editor tab is opened it is highlighted with blue as an active tab. First, you enter input parameters in the tabs that are highlighted with the red box in the screenshot.
You select the profile, data source, asset, timeframe and the interpolation method. For example, if you have an open position and in the range of the same bar, you have set a take profit and stop-loss orders, and they are both available in this bar. If you are using the pessimistic method, the strategy will directly execute the stop-loss order, optimistic — take profit. Shortest Executes the orders in such a way, so it creates the shortest possible route between the way points of the bar - Open, High, Low, Close and all orders in the range.
The Nearest method will execute the order that is closer to the current price. When there is not enough data to know which order the backtester should execute first, the Random method will execute the orders in a random fashion. Strategy tab opens in the main area of the program.
It holds a strategy and provides all tools for editing, exploring, testing and trading a strategy. Double click on the Strategy Properties with your scroll button. Let us return to the main area of the strategy. Below the strategy properties, there are rules for entering and exiting the trade they are under the red box in the last figure. If you click on the Add an Opening Logic Condition, you will see the list of indicators, both the default FSB tools and the indicators, added by the user.
Here you can specify the settings of the strategy indicator, everything is just like in MT4 shift, multipliers, periods of moving averages etc. A forex trading system is build based on Logical Groups that contain numerous conditions for entering trades. You can assign a name to each group and add as many tools to it as you wish. This way, you can build an Expert Advisor that will enter trades according to a few strategies of different types.
However, it is a rhetorical question: how efficient this approach is? And you can make the forex trading system from strategies that work afterwards if you wish. The strategy efficiency is displayed in the chart by one or several lines. If there are a few lines in the chart, then they are equities, the profitability of long and short positions 2 lines , a total change in the deposit.
In the last figure, the balance chart shows that the system must be applied in any case. In addition to sharp, deep drawdowns, the balance goes to zero in the end. Editor tools are helpful when you clearly see what you should have in the end and what trading system you want to build. If so, you can use Strategy Generator a tab in the Control Panel.
The user interface of the Generator is very similar to the interface of the Editor, but there are some differences. First, the upper menu toolbar is completely different. And there is another important thing, you should pay attention to. In the upper right corner of each block, there is an icon. More precisely, there are three options for displaying it: it is completely missing, a lock is displayed, or something similar to a rectangle.
If you have any idea about this, please, do write in the comments. When you have put all the ticks in the blocks, click on the Start button at the bottom of the window. It may take form a few minutes to a few hours to generate a strategy depends on the accuracy, working time, indicators and so on.
We are interested in the Local Repository left vertical menu , where the strategies are stored both generated and downloaded. There are filters that help to arrange strategies in a convenient order. We find the generated strategy while there is a single one, there are no problems with the search and we look at its statistics.
To do this, in the lower right corner look at the item Strategy Slots, and then Account Statistics. In the Strategy window, the program offers different variations of the systems according to the parameters specified; there can be dozens of them especially since all types of indicators are switched on. Based on the account statistics that is the strategy testing , you can make a decision whether to launch the strategy on the real account or to optimize it. If the forward testing the last section is not successful, that is, the curve is either flat or downward at the last section, we delete the strategy without the analysis of statistics.
Below is an example of such a failed strategy. If a forex trading system seems to work, optimize it on the MT4 demo account and compare the statistics in the terminal with the data, calculated by Forex Strategy Builder. There are comments on the Internet, written by those who took the responsibility to develop, employ and analyze the forex trading systems, built by the program. Out of of generated and tested strategies, only 80 turned out to be acceptable, only 10 of them passed forward testing successfully, only a few of them showed relatively acceptable performance, deserving to be tested on a demo account.
The final step is the optimization of a new strategy. Optimization means adjusting particular parameters of the strategy in order to improve its performance. That is why, you can optimize not only new generated strategies but the forex trading systems, already being applied on the real account. We go back to the tab, where we designed and generated the strategy open the Optimizer toolbar.
There are relatively few settings. Like the previous menu, there is the main area and the top toolbar. Click on the Settings tab in the toolbar and put ticks where it is necessary. In the main menu of the Optimizer Settings, correct the indicator settings as you think to be appropriate, again click on the Start and look for the optimized strategy in the Repository.
Strategy Overview is another group of tabs in the left drop-down menu. Here FSB Pro generates a reading-friendly description of the strategy properties and the statistical parameters of the indicators. This is another way to present statistical information.
It consists of the following sections:. Open the tab it is necessary for each Expert Advisor generated and click on the Start button. At the beginning of the article, I have briefly described the methods of exiting a trade optimistic, according to take profit, pessimistic, according to stop loss.
The program compares the charts, constructed with different methods. If there is a single line of the price chart or, there are a few of them next to each other after the test, then everything is alright. If there is a divergence, remove the strategy and start all over again - something went wrong.
Below is an example of such a strategy with an error. Multi Markets. According to this variant opening of a market order is allowed when contrary orders are not closed yet, which is senseless. There can be rare cases when this variant is partially justified. Opening of an opposite order is sometimes acceptable for compensating losses occurring at small corrections after strong price movements.
In such cases an opposite order can be opened of the same or smaller value than the already existing one and then closed when the correction is over. Such a tactic allows not to interfere with the "main" order opened in the trend direction.
In general case several one-direction orders are also possible. This may be justified when an earlier opened order is protected by a Stop order and the criterion pointing at the price development in the same direction triggered once again. However, when creating such a strategy, a developer must be fully aware that in case of a sharp price movement change the placed stop orders may be unexecuted by some brokers at the first price touch.
And the loss will be proportionate to the total value of one-directional market orders. In our example we use variant b of trading criteria correlation. All opened market orders are closed either by a stop order or after a criterion of opening an order in opposite direction triggers here criterion of closing Buy coincides with that of opening Sell and vice versa.
In any trading strategy order sizes should be reasonably limited. In a simple case a fixed order size is used in an Expert Advisor. Before EA operation start, a user can set any size of future orders and leave it unchanged for some time. Further if balance changes, a user can set up a new value of lot numbers of opened orders. A too small order size provides more confidence in operation at the unpredictable market change, but the profit in case of success will be not so large.
If the order size is too large, large profit can be acquired, but such an EA will be too risky. In this example both variants are implemented. A user may choose either to indicate directly values of orders or set the value in percentage from the free margin. A simple trend Expert Advisor tradingexpert. One more criterion in program estimation is its readability. A program is considered to be correctly written, if it can be easily read by other programmers, that's why all main program parts and main moments characterizing the strategy must be commented.
This is also why it is recommended to declare and comment all variables at the beginning of the program. According to rules, external and global variables must be opened before their first usage see Types of Variables , that's why they are declared in the program head part.
All local variables of the function start are gathered and described in the upper function part block immediately after the function header. Rules of declaring local variables do not require it, but also do not prohibit. If a programmer faces difficulties in understanding the meaning of a variable when reading the program, he can refer to the upper program part and find out the meaning and type of any variable.
It is very convenient in programming practice. In this example the preprocessing consists of two parts block The program terminates operation if there are not enough bars in a security window; in such a case it is impossible to detect correctly in block values of moving averages necessary for calculating criteria.
Besides here the value of the variable Work is analyzed. In the normal EA operation the variable value is always 'true' it is set once during initialization. If a critical error occurs in the program operation, 'false' is assigned to this variable and start finishes its operation.
This value will not change in future, that is why the following code is not executed. In such a case the program operation must be stopped and the reason for the critical error must be detected if needed, a dealing center must be contacted. After the situation is solved, the program can be started once again, i.
The described Expert Advisor allows working only with one market order. The task of the orders accounting block block is to define characteristics of an opened order, if there is one. In each cycle iteration the next order is selected by the function OrderSelect. If the selection is executed successfully i.
In the line:. Operator 'continue' stops the iteration and characteristics of such an order are not processed. But if the order is opened for the security, to the window of which the EA is attached, it is further analyzed. If OrderType returns value more than 1 see Types of Trades , the selected order is a pending one. But in this Expert Advisor managing pending orders is not provided.
It means the execution of start must be terminated, because a conflict situation occurred. In such a case after a message about the operation termination start execution is stopped by the operator 'return'. If the last check showed that the analyzed order is a market order, the total number of orders for a security is calculated and analyzed.
For the first of such orders all necessary characteristics are defined. If in the next iteration the order counter variable Total finds the second market order, the situation is also considered to be conflict, because the EA cannot manage more than one market order. In such a case start execution is stopped after showing a corresponding message.
As a result of the order accounting block execution if all checks were successful the variable Total preserves its zero value if there are no market orders, or gets the value 1 if there is a market order for our security. In the latter case some variables set in correspondence with the order characteristics number, type, opening price, stop levels and order value also get their values. In the analyzed example definition of trading criteria block is calculated on the bases of difference between Moving Averages with different periods of averaging.
According to accepted criteria a chart is bull-directed if the current value of the MA with smaller period is larger than the value of MA with larger period, and the difference between the values is larger than a certain value. In a bear movement MA with smaller period is lower than MA with larger period and the difference is also larger than a certain critical value. The fact of significance of any trading criterion is expressed via the value of a corresponding variable. In this case the criterion for closing Sell coincides with that for opening Buy, criterion for opening Sell coincides with that for closing Buy.
It was written earlier that this Expert Advisor is intended for operation only with one market order opened for a security, to which window the EA is attached. To the moment when control in the program is passed to the order closing block it is known for sure that at the current moment there are either no orders for the security, or there is only one market order.
That's why the code in orders closing block is written so that only one order can be closed successfully. This block is based on the infinite loop 'while', the body of which consists of two analogous parts: one for closing a Buy order, another for closing a Sell order. In the header of the first operator 'if' condition for closing a Buy order is calculated Sell orders are closed in the analogous way.
If the type of an earlier opened order corresponds to Buy see Types of Trades and the sign for closing Buy is relevant, control is passed to the body of 'if' operator where a request to close is formed. As an order closing price in the function OrderClose the value of a two-sided quote corresponding to the order type is indicated see Requirements and Limitations in Making Trades.
If a trade operation is executed successfully, after a message about the order closing is shown the current 'while' iteration is stopped and the execution of the order closing block is over. Critical errors are divided into two types - those, after which a program execution can be continued for example, a common error and those, after which execution of any trade operations must be stopped for example, blocked account.
If the function returns 0, the current start execution is stopped. If during error processing it is found out that further program execution is senseless for example the program operates on an old client terminal version during the next start the execution of the special function start will be terminated in the block of preliminary processing when analyzing the value of the variable Work.
Amount of lots can be calculated in accordance with a user's settings following one of the two variants. The first variant is a certain constant value set up by a user. According to the second variant the amount of lots is calculated on the basis of a sum equal to a certain percentage set by a user of a free margin.
At the beginning of the block of defining the amount of lots for new orders block necessary values of some variables are calculated - minimal allowed amount of lots and step of lot change set up by a broker, free margin and price of one lot for the security. In this example the following is provided. If a user has set up a certain non-zero value of the external variable Lts, for example 0. If 0 is assigned to Lts, the number of lots Lts is defined on the basis of the variable Prots percentage , free margin and conditions set up by a broker.
After Lts is calculated, a check is conducted. If this value is lower than the minimal allowed value, the minimal allowed value is accepted. The block of opening orders block like the bloke of opening orders is an infinite loop 'while'. In such a case after rates are refreshed prices for stop levels are calculated. Values of stop levels are initially set by a user in external variables StopLoss and TakeProfit. In a general case a user can set values for this parameters smaller that a broker allows.
Besides a broker may change the minimal allowed distance at any moment it is an often case at strong market movements, for example, before important news release. That's why before each order opening stop levels must be calculate taking into account values set bu a user and the minimal allowed value set up by a broker. If the value set by a user corresponds to a broker's requirements, this value is returned.
If it is smaller than the allowed value, the value allowed by a broker is used. Prices of stop requests are calculated from the corresponding two-sided quote see Requirements and Limitations in Making Trades. A trade request to open an order is formed using the function OrderSend. For the calculation of order opening price and prices of stop requests the two-sided quote values corresponding to the order type are used. If a trade operation was successful i.
If an order was not opened and the client terminal returned an error, the error is processed according to the algorithm described earlier. The analyzed Expert Advisor code is oriented to the implementation of a certain strategy. Note, some program lines contain variables and calculations that would be changed, if the strategy were changed. For example, according to the accepted strategy the Expert Advisor is developed to work only with one order.
This allowed to use the variable Ticket both for the identification of a closing order number in block of closing and for the identification of a success of a trade operation execution when opening an order in the block of opening In this case such a solution is acceptable. However, if we take the analyzed code as the basis for the implementation of another strategy for example allow opposite orders we will have to introduce one or several variables to be able to recognize numbers of opened orders and identify the success of trade operations.
In further strategy modifications we will have to change come program lines containing part of logics contained in the source strategy. Namely in the order accounting block we will not have to terminate the program operation if there are several open orders for a security.
Besides, conditions for opening and closing orders will alslo change. This will entail the code changing in blocks of opening and closing orders. On the basis of this analysis we can easily conclude that the described simple Expert Advisor is not perfect. In a general case, for the implementation of order accounting one should use a universal function based on using data arrays and not containing logics of a certain strategy.
The same can be said about the blocks of opening and closing orders. A more complete program must contain a main analytical function, all other user-defined functions must be subordinate to it. This analytical function must contain a program code, in which all conditions for the implementation of any strategy are analyzed; all subordinate functions must perform limited actions. The function of accounting orders must only account orders, functions of opening and closing orders must only open and close orders, and the analytical function must "think" and manage all other functions, i.
Problem Create a trading Expert Advisor. Preliminary Arguments Before starting to program a trading Expert Advisor, it is necessary to define general principles of a future program. Structure of a Simple Expert Advisor Below is a structural scheme of a simple Expert Advisor constructed on the basis of several functional blocks, in each block a certain detached part of calculations.
Trading Strategy Market prices are constantly moving. Trading Criteria In this example we will try to construct a trend Expert Advisor, i. Number of Orders In this example we analyze an Expert Advisor that admits presence of only one market order, pending orders are not provided. Relation of Trading Criteria From this position it becomes clear what relations are possible between trading criteria.
Size of Opened Orders In any trading strategy order sizes should be reasonably limited. Programming Details A simple trend Expert Advisor tradingexpert. EA doesn't work. Waiting for response.. Trying once again.. Waiting for a new tick.. In the block external and global variables are described.
Block of preliminary processing In this example the preprocessing consists of two parts block Accounting orders The described Expert Advisor allows working only with one market order. In the line: if OrderSymbol! Calculating Trading Criteria In the analyzed example definition of trading criteria block is calculated on the bases of difference between Moving Averages with different periods of averaging. Trading criteria accepted in this example are used for educational purpose only and must not be considered as a guideline when trading on a real account.
Closing Orders It was written earlier that this Expert Advisor is intended for operation only with one market order opened for a security, to which window the EA is attached. Calculating Amount of Lots for New Orders Amount of lots can be calculated in accordance with a user's settings following one of the two variants.
