Hereby Forex Signal Transmitter and Receiver, a tool to send/receive text messages between MT4 instances! It includes 2 sample MQL files, 1 DLL file and its source code (using Visual Studio 2005, C++)

How it works :

Well, with SendSignal, it stores a text message of up to 255 characters long in a Registry (”HKEY_CURRENT_USER\Software\TradeSwitch\Signal s”) under a subfolder named with the first string parameter of this function (”Name”), e.g. “EURUSD”. This text message is then stored as a key-value pair in that subfolder. The key is defined with a shortable DateTime string, the value is filled with that message. Each time when SendSignal is called, a new key-value pair is then added in sorted order.

When ReceiveSignal is called with the Name string as parameter (like “EURUSD”), the oldest key-value pair that is still stored in that subfolder is read from and deleted afterwards. The value string is then returned back as result.

With FlushSignal, all key-value pairs that are still left stored during SendSignal in the Name selected subfolder are deleted. Used for restarting EA in Init function.

How to Install :

1. Put both MQL files in expert subfolder
2. Put DLL file in expert/libraries
3. Don’t forget to enable DLL function in MT4 Options
