Will this 69% open-source strategy continue to work?

It is 6h EURUSD, so I’m not sure what are the odds of it continuing to be profitable. Any ideas?

i d only look to sell EURUSD next weak, as it showed weakness. Fake break of downward channel and previous daily resistance resulting in a nice selloff(upthrust). i ll wait for a 50% to 61.8% retracement of that daily pin and jump on the selling wagon unless something changes(strenght coming in, demand). this is just my opinion. cheers
