Inverse Mode
I think this would be an easy and helpful implementation to the EA. Basically there would be a input to turn Regular or Inverse mode on. Inverse mode would make it so that the entry and exits for buy/sells would be reversed. This would be able to turn a losing strategy into a winning one, especially on set files with martingale disabled, which does not perform very well compared to other strategies.
We already have Reverse option in Oscillator signal. We also have opposite MA filters (you can use "below" instead of "above").
So, all you need is to reverse TDI and IdentifyTrend? Do you think it have sense?
