Quote Monitoring (Memory Mapped File) - MetaTrader 5 Expert | MT5 EA Download - MetaTrader 5 Resources
The Expert Advisor is a sample memory map using a DLL that uses file mapping functions.
In this example, the Expert Advisor creates a virtual (memory mapped) file and starts updating the quotes of the symbol.
In this way, Expert Advisors can exchange data (for example, quotes) using common memory-mapped files.
The format of memory mapped files is the same as that used in the MetaTrader 4 Expert Advisor . This means you can exchange quotes between MetaTrader 5 and MetaTrader 4 .
Other data exchanges can be organized in a similar way.
The code has lots of comments and logs.
MemMap32/64.dll library (see MemMap32/64.zip) must be placed in: terminal_data_folder\MQL5\Libraries
