Hi,

I am searching for a custom fitness that I can enter that will eliminate 0 MAE trades (trades whose total drawdown is equal to commission+slippage only).

Does anyone have suggestions? Is the custom fitness section documented (have not seen it)?

Hi Mike
Not that Im aware of but on a similar note, i was going to look at the excel export and the MAE/MFE and do some analysis on these ie what is the absolute max values, 1 & 2 standard deviations of these values.
I was going to add these to my summary report.
So i guess with the excel file you could obtain the information you seek?

Not much information on custom fitness. If you don't know it yet:

Custom Criteria Optimization - MultiCharts

SetCustomFitnessValue - MultiCharts

And have a look at the Signal !optimize by sharpe ratio!

Yes, but it is not practical. I know, because I've been doing it. The entire optimization is a waste of time because I don't want these trades to be "cherry picked". I am looking through 2+ years of backtests with 50,000+ trades. I am finding that in many cases a small percentage (say 5-10%) of trades are 0 MAE, yet they are making up over 50% of profits. I don't like this and want those thrown out of the optimizer.

Yes but there is no documentation on the reserved words supported. So it is impossible to build a function without knowing the reserve words supported.

Click on the word MAE above for an explanation.

The impact is that I have found the optimizer is attracted to 0 MAE trades by default, and I believe 0 MAE trades are extremely unlikely to be repeated in a live cash trade, so I want to de-emphasize them in the backtest.
