I've seen this signals working for so many times during past few years, but I rarely share it on here because it's one of my secret weapons. How it works is that every time when it tags along lower BB, market tends to fall hard over next few days (a big plus is that I don't have to hold my trades for few days so I can avoid time decay problem.) This signal is among some other reliable signals that I'll use to catch big fishes next time.
I'm going back to bed right now. I didn't get enough sleep over last few nights because of being nervous of holding those big trades. Now, I can relax a bit.
