It would be great to have a variable random spread that can fluctuate between different testing periods to simulate a live spread that fluctuates, as research has led me to notice that spreads can indeed change but others can be fixed.

For any backtesting or forward testing this would be cool unless it is already possible?

So for example.

Spread = 1.6*PIP to 2.5*PIP

Rate of change = 0.1*PIP & 25%..


Cheers.
