All right people... !!
Here is one more crazy stupid experiment by me while boosing. I call it..... Well Bollinger Bands for now..
If you like it and find it useful, give me suggestions, we can name it.

Its was just an idea of removing unnecessary opposite bands (noise i say) and it turned out to be useful to me.
After finishing, I saw good locations of support and resistance levels building.
Just connect the flat lines it create.

See if that interests you...!! Please leave comments below even if you are not in mood.
