Expert Advisors

Settings of working with Expert Advisors are grouped in this tab.

Expert Advisors in the terminal are programs written in MetaQuotes Language 4 and allowing to analyze and trade in the automatic mode (auto trading). The description of how to create and use experts is given in the «Auto Trading» section. The given section describes only settings common for all experts:

• Allow Auto Trading – this option allows to enable or disable the performing of trade operations by Expert Advisors and scripts. If it is disabled, scripts and Expert Advisors will work, but they won’t be able to trade. This limitation can be useful for testing the analytical capacity of an Expert Advisor in the real-time mode (not to be confused with testing of Expert Advisors on history data). Automated trading can also be allowed or disabled using button on the toolbar.
  The option enables/disables autotrading for the entire terminal. If you disable it, no Expert Advisor will be allowed to trade, even if you enable autotrading in the EA settings. If you enable it, the Expert Advisors will be allowed to trade, if autotrading is enabled in their settings.

• Disable Auto Trading when the account has been changed – this option represents a protective mechanism disabling trading by Expert Advisors and scripts when the account is changed. It is useful, for example, when one changes demo account for a real one.
• Disable Auto Trading when the profile has been changed – a large amount of information about the current settings of all charts in the workspace is stored in profiles. Particularly, profiles contain information about Expert Advisors attached. Expert Advisors included into the profile will start working when a new tick incomes. Having enabled this option, one can hinder the trading by the Expert Advisors launching when the profile has been changed.
• Disable Auto Trading when the charts symbol or period has been changed – if this option is enabled, then when the period or symbol of a chart is changed the expert advisor, which is attached to it, will be automatically prohibited to perform trade operations.

• Allow DLL imports (potentially dangerous, enable only for trusted applications)
  To enlarge their functionality, expert advisors can use DLLs (dynamic-links libraries). If it is enabled, such libraries can be used without any limitations. If this option is disabled, no expert can use external DLLs. It is recommended to disable import when working with unknown experts.
• Allow WebRequest for listed URL
  The WebRequest() function in MQL4 is used for receiving and sending information to websites using GET and POST requests. To allow an MQL4 application to send such requests, enable this option and manually explicitly specify the URLs of trusted websites. For security reasons, the option is disabled on default.
  To delete an address from the trusted list, select it and press «Delete» button.

Attention: Values of options named «Allow Auto trading», «Allow DLL imports (potentially dangerous, enable only for trusted applications)» and «Allow WebRequest for listed URL» specified in this window are default parameters for MQL4 programs newly attached. They do not influence the operation of expert advisors, custom indicators and scripts already running.

Expert Advisors

Expert Advisors (experts) are programs in the terminal that have been developed in MetaQuotes Language 4 (MQL4) and used for automation of analytical and trading processes. They allow to perform prompt technical analysis of price data and manage trading activities on basis of signals received. The entire routine work of technical analysis and trading can be given to experts. An expert can perform analytical and trading operations for any symbols or periods independent on whether the corresponding chart was opened or not.

Working with experts means:

• Creation of an Expert
  To create and compile an expert, one has to use the built-in «MetaEditor». It is a constituent of the client terminal and represents a convenient development environment of MQL4 programs.
• Expert Setup
  Before using of experts, one has to set up them first. Working parameters common for all experts are set in the client terminal settings. Besides, each expert can have its own settings.
• Launch of an Expert
  To launch an expert, one has to impose it into the chart. As soon as a new tick incomes, the expert will start executing.
• Expert Shutdown
  An expert advisor is shut down after it has been removed from the chart.

New features of trading robots development

The new MQL5 language syntax is similar to that of MQL4 but MQL5 programs work up to 20 times faster. This is possible because all MQL5 language functions are implemented as efficiently as possible, while the compiler aggressively optimizes the obtained executable EX5 code to achieve the high speed of MQL5 applications.

The second reason is the implementation of asynchronous operations executed in a fraction of a millisecond. These operations open opportunities previously unavailable for many professional traders. With the fifth generation platform, you do not need third-party connections to exchange protocols. Besides, you do not need to place your terminals as close to a broker as possible. Just get a VPS next to the trading server and send your fast MQL5 robot to trade there directly from the terminal. Low network costs, high Depth of Market refresh rates and asynchronous order sending accelerate trade operations dozens of times allowing you to develop trading robots for the new class of strategies.

MQL5 implements event handling making it simpler and easier to build complex trading algorithms. At each trading operation, the Trade and TradeTransaction events are sent to the terminal to be processed by the appropriate handlers. Orders, positions and deals are considered separate entities in the new platform, since now you can trade not only usual Forex symbols, but also exchange instruments. The Standard Library offers the ready-made Trading Classes to work with trading functions. The classes simplify the development of trading operations. You only need to declare the CTrade type variable to get the entire functionality necessary to work with all order types.

To quickly check your trading idea, assemble a robot using MQL5 Wizard modules without writing a single line of code. The ready-made trading signal, open position tracking (trailing stop) and money management (setting volumes in trading operations) modules allow creating an unlimited number of trading strategy versions and combining several types of signals in a single EA. Thus, the new terminal makes it possible to develop complex strategies even with no programming skills.

Another advantage of MQL5 language is the ability to work with the Depth of Market and access the tick history. Analyze Time & Sales and develop strategies based on price change and deal volume directly in an EA. In the new platform, the trade server stores a tick history of each symbol and sends it to the terminal on request when testing on real ticks. The MetaEditor developer environment allows debugging and profiling EAs directly in the strategy tester enabling a quick check of trading algorithms in different market situations. In the tester, such a test will take a few minutes and hours, while the conventional test of robots online will take days and weeks.
