if you have a gameplan with statistical evidence, then yeah, you might have found an edge, which was based on historical data.
if you can really tell, that if x happens y will follow z% amount of time and you have a money management to back it to be proficient, well done.
one crucial point which would also interest me is, how much heat you need to take for one trade to workout, i.e. maximum adverse excursion. or for trades that didn't workout, maximum favourable excursion, i.e. that trade didn't work out but how much did it went in my favour before turning against me.
i, personally, would not be able to pull the trigger when i knew, based from backtesting this idea, that the majority of time price went against me and turned before stopping me out by a couple of ticks. too much heat for my psychology to handle that, but that is personal. you might be different.
on the other side, if you see, from your backtest data, that price moved in your favour before turning and stopping you out, i would further dig down to see if advanced money management could turn it to be profitable.
maybe trading multiple lots, taking one lot off before initial TP point and then moving the other lot to breakeven and in case price moves further letting one lot to be a runner.
but those are fine tuning your findings. then it comes to trading the hard right edge of the chart. thats the difficult part, i guess.
