Following chart with the additional parameters anticipates when a %B 20 (being the price) will turn even if you have not reached the 0.1 level or below-i.e. turning midway..
Example: When price reached the lower boundary of teh one deviation at 1311.72..what tells us that it would turn and not go lower looking for the 2 deviation..i.e. lower values? ANSWER:%B10 wnet back into the 10.2 BB in the indicator above....forcing %B20 to turn back up.
When %B 10 goes out of 10.2..it is a law that %B20 will turn when %B10 goes back in to the 10.2 bands..
Midaway turns anticipation is resolved within the price relative framework.
Also, when %B20 touches the 10.2 deviation above at 1309.17..that is a bottom...but that is %B20 telling you this is bottom in its own way...
Rotor: I hope you are catching this..tons of signals revealed by applying BBs on indicators ..
