As well as many technical indicators and
line studies, there is built-in language for
trade strategies programming MetaQuotes Language 4. Using
this language, you can create
Expert Advisors,
Custom Indicators and
Scripts. Expert Advisors can
analyze the situation on the market, make decisions, put pending orders, and open positions
in on-line mode without trader's participation. Custom Indicators, just like technical
ones, can analyze the situation on the market and generate various signals. As for Scripts,
they are designed for single execution of some actions.
