I'm through about 40% of the SPY systems for next bar open, most of the longs, will move to shorts next week. Most of the systems I've been able to get similar or better results on the historical stats. A few systems though I may or may not consider leaving closing bar such as CCI, and Hi Mid Lo. The CCI systems tend to enter on an up candle anyway and waiting another day to enter is maybe not as ideal. And for very short term holding systems like the hi mid low that hold an average of 3-4 days, statistically moving it to the following morning is 25% of the historical time.  Again still too early for me to make decisions here, I'm just relaying some info. 

the other tough thing is the 2nd and 3rd entries. It's difficult getting the code working right and I'm waiting on a new version from James that hopefully does what I want.   The 2nd and 3rd entries instructions will be different than what you guys are used to now:

For example if a system is taking a second entry - that entry will be NOT just be at the next morning open -  I will be giving limit prices. So the alert might be: SPY bear long triggered a 2nd entry for the next day open with a buy limit order at 392 or better - meaning you will use a limit order and at times the trade MAY not fill that day! 

otherwise it's a long process and tedious but it's yielding answers and will be beneficial. Especially if I add say 5 or 10 ETFs, logistically trying to get those signals out the last few min of the day is too much, best to have the signals that afternoon and you have all night to see them and enter the following day.
