Bollinger bands are not prediction machines. They are more like the gutters at the bowling alley. They are math based and rear view mirrors of what has happened in the past. They are customizable to your settings.
I like to use them as a quick reference to tell me what is normal price action in the past. I would never use them alone. Combing valuation of the company, along with macro view of economy, and only then using technical like Bollinger bands is the way I like to trade. Bollinger Bands give me confidence to engage, thats it.
In the video I cover a case study of a vertical spread trade in TJX and how Im using Bollinger Bands as a rough guide for my placing my option strikes.
Hope you enjoy the discussion. rocket ship and comment if you do ! Cheers!
