The EA I've built is designed to close trades that are already open as the MacD line crosses the signal line. The one I've provided closes "buy" trades (there is another that closes "sell" trades).
The problem I'm having is with cross talk. When a trade on one pair closes as designed, other trade pairs are also closed even when the criteria for closing is not met.
I've individualized the EA for pairs as much as I can determine, but still get this cross talk. What could I be missing? If I have to build a separate EA for each and every pair, I'll do so if MT4 will hold them all.
