The lines looked really messy, without any pattern, or at least i couldn't figure it out. No pattern in either for my eyes (rookie eyes!!!). Therefore, I plotted only the histogram which looks really nice, with many divergences when the stock was at the buy zone.
At the present time, a is taking shape. A reverseal candle (like in the past) would be the next signal. A move up after that candle would be the kick off of a rally.
A strong close below this buy zone would close this trade and would make me aware of the short side.
