This version was not found to be profitable by futurestruth.com with or without at close orders. It had about 10k of drawdown on the es in the last 3 years using only 1 contract.
Since I know how to position size myself accordingly, I could have picked up $58,000/$20/point = 2900 NQ points is the equivalent of what that system has made, some with more than 1 contract of position sizing obviously, but I usually duplicate about a 4:1 leverage factor.
