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.
I just got 49.5 points or the equivalent on ND or NQ on my last trade. So saying 23.5 with 11 trades, boy, just move on. I could go one further at www.collective2.com/go/pairsqidqld . 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.
This is something I've put together, it's inspired by this thread, so it's not exactly the Jack Hershey's method, although it uses some of it's ideas. Monday Feb 9 +$290 trading 1 car after commission and 1 tick slippage
