I just got "Bollinger on Bollinger Bands" by John Bollinger. I have been using this indicator since I started tradding and am just coming to understand how to use it properly. I mostly trade the EUR/USD pair and I was curious how other people have it set up in general and on different time frames. Currently I have it set the same on the 1h, 4h and 15m charts all set at 20 periods and 2 deviations. I downloaded the advanced version which allows decimal point accuracy. I also downloaded the Bollinger Bands Decimal Percentage Oscillator which has the same settings.

Anyway I was just curious how other traders have this indicator set up and anything they have learned from it.
