EUR/USD Bollinger Band Discussion

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.

I am slightly familiar with the indicator, but might I suggest that you only stick with the default settings. See what all the other traders in the world are seeing so that you can gain an edge over them based on your understanding of price, the indicator, and the trend.

I use BB as floating S/R with default setting.

I pretty like the 4 hour Bolling Band. It show you the movement on when it is best time to entry. Also, it can help me to set the stop loss, take profit.
