Hi,

I have enabled commission in backtesting, and it works, but I don't want to add a minimum commission fee or a per unit commission fee. 

I want to add commission as a percentage of the trade. For instance, I want to be able to add commission as say 0.2% of the value of the trade.

I googled it and see that NinjaTrader say that it has been a requested feature for many years and they will say when it is implemented. So it doesn't look as if they have implemented it yet.

Do you know of a workaround to add commission to the trades as a percentage of the trade? Could it be added "manually" to the trade?

Thanks
