I would like a simple strategy to run in the background of Ninjatrader that will close all open positions in an account when the daily loss limit is exceeded. I trade two accounts, so each account will have its own daily loss limit. I also trade multiple instruments (ES and NQ) and would need the strategy to exit all instruments when the daily loss limit is exceeded. I would like the daily loss limit to be changeable. Daily loss is defined as the cumulative dollar p/l per account excluding commissions or fees.
