I was wondering if anybody of you know a reliable way to programmatically abort a MT4 backtest.
The point is that if during an optimization pass a given halt condition is met, (e.g. DD > 5% or a custom OnTester() value is over a threshold etc...) there's no reason to continue the test to the end date.
Actually i use a work-around setting a boolean flag ABORT to true and at the OnTick() beginning just
if ( ABORT ) return;
... but this is a sub-optimal solution.
