I guess this is where fear come into play, I am afraid that because that RET is not significant enough, my rules I will not work so I avoid it instead.
Perhaps you need to rethink what you mean by "significant". Price falls out of that range, then barely re-penetrates it before failing, the most important factor being failure. If you had placed a sellstop at 50, you would not have been stopped in if price were serious about re-entering that trading range.
There is also the issue of "trusting" a lower high or higher low or whatever. Trust is not a factor. If your rules or guidelines call for shorting a lower high after a demand line is broken, then you have to take it. You'll learn something whether the trade is profitable or not.
