MT4 Debugging
Stop an EA from opening repeated trades on the same signal.
Overtrading is usually a state problem. The signal remains true across many ticks, and the EA has no memory that it already acted.
Search intent
The EA opens repeated trades and the developer needs duplicate-entry controls.

Detect new signals, not persistent conditions

MaxOpenTrades and cooldown rules give the EA hard limits even when signal logic fails.
Log why the second trade was blocked
If the EA cannot explain why it did not open a duplicate, the gate is not observable enough.
