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.

Hope this helps.
