布林带支撑和阻力通道 (Bollinger Band Support and Resistance Ch)

My idea is simple. Use Bollinger Bands to create support/resistance levels as well as a pivot point with the median bollingerband line.This allows you to customize the length of trend you want to look at. Keep the BandPeriods all the same but change the deviations. This creates bollinger support/resistance channeled band levels.
ex. -3-2-1 M +1+2+3
You can change the deviations to suit your entry/exit rules. Just an idea i wanted to throw out there. Any comments would be appreciated.
