Look at the bigger picture

The Orange lines are the upper and lower bands. I connected the bands or two highs and two lows. **
The green line shows 200ema at a 1W timeframe.

Connecting bollinger bands UB and LB - Even if there’s a breakout or breakdown, there’s a chance it’ll bounce back from the previous trend of bollinger bands.

Sorry, I’m not good at English. Tried my best to explain.
