gents, i have a daytrading system that i am currently forward testing. recently, it reached an equity high of +52R. this corresponded with a max drawdown of -3R from equity highs. not bad!! a period of drawdown then followed, taking me -14.5R from the equity high. the system is currently recovering back to its equity highs. which brings me to my question.. would it be best to have a killswitch on the system at say, -10R from equity highs, at which point you would stop trading the system until new equity highs are made? my thoughts: the pros of this method would be that, should the system stop working, you will not trade it all the way back to zero. simply put, you would get out with a -10R loss from the equity high and if new equity highs are never made again, then you would never trade the system again. the cons of this method would be that you, if the system then recovered, you would have be accepting a -10R loss but not riding the +10R recovery back up to equity highs. this would affect your trade statistics. to me, it makes sense to have a killswitch at some point to protect my account should the system fail. does anyone have any comments?
