To provide more clarification, this was all done using 1X3 box/reversal, and was done more with a position trading view than day trading (plus I think it's easier/more accurate to backtest using daily data).
I think with the addition of relative strength against SPY and against the appropriate sector ETF will make the signals more reliable and have less losses.
I am still trying to figure out a good exit strategy - a PnF sell signal might make me exposed to some pretty large losses in the case of a huge run up, and subsequent retracement.
After I can get the comparison to relative strength working, I want to add bullish support/bearish resistance trendlines, which seems like it'll be the hardest part yet, for some reason.
