The lines are bit thick, but I see many whipsaws around those lines too. You can get stopped out several times at least. Also when not reached and then it reverses totally, hmm... that makes it difficult to trade. Then goes above with correction or not and bounce several times along the line. How would you trade this ? Any systematic rules, no hindsight here ? It also depends very much on your scale, so you have it curve fitted here with hindsight bias. And then you want to tell me you could or did make how many points with this ? Any longer term statistics from your trades with this ?
