Feature Request related to the Strategy Tester calculating drawdowns on equity

 
It's really nice to have the Strategy Tester basing drawdowns on equity but could we have the option of choosing the drawdowns to be calculated on balance or equity when we backtest or optimize?

I ask this because a simple spike can throw the optimizer way off when optimizing on based on equity.

It would be much nicer to be able to backtest both ways to we could get a more accurate picture of how the EA does.

thanks
