Quote from Wayne Gibbous:
It's pretty much a loser.
Here's AAPL, long only, buy 1000 shrs at the Open if the Open is Less Than the Previous Close (gap down).
Sell at a limit $0.10 higher than the Open (entry). If limit is not hit, Sell at Close.
That's too funny... if you are smart enough to do run a backtest, you should be smart enough to EXIT if the instrument enters, let alone exits, the opposite trade zone!!
Obviously, you are biased!
Be objective, anyone can make a strategy lose... show you can make a strategy win!
