Forex signals mql5 programming

Method overriding is not required. You must override the method if there are any setup parameters. If at least one of the parameters is incorrect, it must return false further work is impossible. Base class CExpertSignal has no adjustable parameters, therefore, the base class method always returns true without performing any checks. It is called from the expert after all the parameters are set and their correctness is successful verified.

The method should be overridden if the trading signal generator uses at least one indicator or timeseries. Base class CExpertSignal does not use indicators or timeseries, therefore, the base class method always returns true, without performing any action. Methods of checking the signal of position opening: 1. It is called by an expert to determine whether it is necessary to open a long position.

The method must be overridden, if it is expected that a signal of a long position opening will be generated. If the condition is met, the variables price, sl, tp, and expiration references to which are passed as parameters must be assigned appropriate values and the method should return true. If the condition is not fulfilled, the method must return false. Base class CExpertSignal has no built-in algorithm for generating a signal of a long position opening, so the base class method always returns false.

It is called by an expert to determine whether it is necessary to open a short position. The method must be overridden, if it is expected that a signal of a short position opening will be generated. If the condition is satisfied, the variables price, sl, tp, and expiration references to which are passed as parameters must be assigned appropriate values and the method should return true.

Base class CExpertSignal has no built-in algorithm for generating a signal of a short position opening, so the base class method always returns false. Methods of checking the signal of position closing: 1. It is called by an expert to determine whether it is necessary to close a long position.

The method must be overridden, if it is expected that a signal of a long position closing will be generated. If the condition is satisfied, the variable price the reference to which is passed as a parameter must be assigned the appropriate value and the method should return true.

Base class CExpertSignal has no built-in algorithm for generating a signal of a long position closing, so the base class method always returns false. It is called by an expert to determine whether it is necessary to close a short position. The method must be overridden, if it is expected that a signal of a short position closing will be generated. Base class CExpertSignal has no built-in algorithm for generating a signal of a short position closing, so the base class method always returns false.

Methods of checking the signal of position reversal: 1. It is called by an expert to determine whether it is necessary to reverse a long position. The method must be overridden, if it is expected that a signal of a long position reversal will be generated. In the CExpertSignal base class, the following algorithm for generating a long position reversal signal is implemented: Checking for a signal to close a long position. Checking for a signal to open a short position. If both signals are active the conditions are met and the close and open prices match, the variables price, sl, tp, and expiration references to which are passed as parameters are assigned the appropriate values and the method returns true.

If the condition is not fulfilled, the method returns false. It is called by an expert to determine whether it is necessary to reverse a short position. The method must be overridden, if it is expected that a signal of a long position reversal will be generated according to the algorithm that differs from the one implemented in the base class. In the CExpertSignal base class, the following algorithm for generating a short position reversal signal is implemented: Checking for a signal to close a short position.

Checking for a signal to open a long position. Methods of checking the signal of pending order modification: 1. It is called by an expert to determine whether it is necessary to modify a pending Buy order. The method must be overridden, if it is expected that a signal of modification of a pending Buy order will be generated. Base class CExpertSignal has no built-in algorithm for generating a signal of modification of a pending Buy order, so the base class method always returns false.

It is called by an expert to determine whether it is necessary to modify a pending Sell order. The method must be overridden, if it is expected that a signal of modification of a pending Sell order will be generated. Base class CExpertSignal has no built-in algorithm for generating a signal of modification of a pending Sell order, so the base class method always returns false.

Develop Your Own Generator of Trading Signals Now, after we have reviewed the structure of the CExpertSignal base class, you can start creating your own trading signals generator. As mentioned above, the CExpertSignal class is a set of public virtual "ropes" - methods, using which the expert may know the opinion of the trading signals generator about entering the market in one direction or another.

Therefore, our primary goal is to create our own class of trading signals generator, deriving it from the CExpertSignal class and overriding the appropriate virtual methods, implementing the required algorithms. Our second problem which is not less important - to make our class "visible" to MQL5 Wizard. But, first things first. Creating the class of the trading signals generator Let's begin. First, we create for example, using the same MQL5 Wizard an include file with the mqh extension.

Remove the unnecessary parts and add what is required include file ExpertSignal. As a basis for our trading signals generator, we take the widespread model "price crosses the moving average". But we make one more assumption: "After crossing the moving average, the price moves back, and only then goes in the right direction.

Generally, when you are writing something, do not skimp on the comments. After some time, reading a carefully commented code will be so comfortable. In our case, this is the open price and the close price of the previous bar, and the value of the moving average on the same previous bar. Custom indicators, as well as standard ones, cannot trade automatically, but only implement analytical functions. Custom indicators can utilize values of other indicators for calculations, and can be called from Expert Advisors.

Script is a program for a single execution of an action. Unlike Expert Advisors, scripts do not handle any event except for trigger. A script code must contain the OnStart handler function. Service is a program that, unlike indicators, Expert Advisors and scripts, does not require to be bound to a chart to work.

Like scripts, services do not handle any event except for trigger. To launch a service, its code should contain the OnStart handler function. Services do not accept any other events except Start, but they are able to send custom events to charts using EventChartCustom. Library is a set of custom functions. Libraries are intended to store and distribute commonly used algorithms of custom programs.

Include File is a source text of the most frequently used blocks of custom programs. Such files can be included into the source texts of Expert Advisors, scripts, custom indicators, and libraries at the compiling stage. The use of included files is more preferable than the use of libraries because of additional burden occurring at calling library functions. Include files can be stored in the same directory where the original file is located.

Program code is written with functions. The library of user functions is intended for storage and distribution of blocks of user programs. Included file is the source code of user files, - EAs, scripts, libraries at compile time. The MQL5 language has a specific subsystem of the compiler, which carries out the preliminary preparation of the source code before compilation. Using the preprocessor, functions are introduced into MQL5 programs, constants are declared, files are inserted, etc.

How to use the MQL5 language MQL5 allows creating interactive programs tailored to the individual needs of any trader. One script runs once on the price chart, and stops after performing its tasks. Also a script can run, performing a single operation, in an infinite loop format, until it is stopped by the trader.

There can be many indicators on the chart, they work until they are stopped. Indicators calculate values based on price data contained in indicator buffers. Advisors and robots are designed to automate trading operations, and can also be used to analyze the current situation in the market and perform other tasks. Programs in MQL5 are created using the event-driven model. They react to any event - price change, implementation of an order, timeframe change, etc.

In general terms, step by step it looks like this. Start MetaEditor through the trading interface of MT5 picture 1 it is loaded on your computer simultaneously with the trading service , for example, by clicking on the appropriate icon or by pressing F4 on your keyboard. The editor will appear fig.

We choose and click on the "Next" button. In both cases a window will appear in which you should first give a name to the created Expert Advisor Fig. The selected parameters can also be deleted by clicking on the appropriate button. After selecting the option, click "Next", a window will appear, in which you will be prompted to select event handlers for the Expert Advisor Fig.

If after calling the MQL Wizard the "Expert Advisor Generate " function is selected, then step by step select the name the symbols and timeframe are already specified in the parameters , add parameters for signals, add trading parameters, money management parameters Fig. Graphs Community of traders and forum All questions on the development and use of MQL5 are addressed in the community pages.

The problem is that the forum is very large and it takes time to find the information you need. First of all, you should read the rules of the section. On the site, you can register as a subscriber or as a signal seller. Subscription can be paid or free, and it allows you to apply trading signals on your own trading account. Each member of MQL5. A member of the community can also sell signals if he accepts the terms of the Trading Signals Broadcasting Agreement and goes through a special registration procedure.
