Dear all, this is not the Precis EA by Nikolay on its own. All trades from Precis are copied to this demo using a filter EA with its own set rules. The filter EA then decides which positions to take and manages the trade from there. Risk is also managed by this EA. This is a proprietary solution which is not for sale unfortunately. Because of this there is no way to just exchange set files for Precis. Precis(and all of Nikolay's EAs) are very good but unfortunately he does not test them thoroughly.
The recent crash in this particular demo is due to increasing the risk from 2% to 5% as a way to push it to its limits. It has been running on 2% without issues but drawdown can be scary at times depending on your risk appetite!
I am also running this privately on live accounts without issues.
