Technical Indicator Functions

All functions like iMA, iAC, iMACD, iIchimoku etc. create a copy of the corresponding technical indicator in the global cache of the client terminal. If a copy of the indicator with such parameters already exists, the new copy is not created, and the counter of references to the existing copy increases.

These functions return the handle of the appropriate copy of the indicator. Further, using this handle, you can receive data calculated by the corresponding indicator. The corresponding buffer data (technical indicators contain calculated data in their internal buffers, which can vary from 1 to 5, depending on the indicator) can be copied to a mql5-program using the CopyBuffer() function.

All indicator functions have at least 2 parameters - symbol and period. The NULL value of the symbol means the current symbol, the 0 value of the period means the current timeframe.
