Alternate Bollinger Bands in Multiple Time Frame minutes. (J)

Description :
Bollinger Bands were invented by John Bollinger . Used to confirm trading signals, normally from a Momentum Indicator , the bands indicate overbought and oversold levels relative to a moving average.
Bollinger Bands are calculated at a specified number of standard deviations above and below the moving average, causing them to widen when prices are volatile and contract when prices are stable.
Bollinger originally used a 20 day simple moving average and set the bands at 2 standard deviations, suited to intermediate cycles.
