bu=BollingerUp[p](fi)
bd=BollingerDown[p](fi)

breakValue=0

// color variable
redColorValue=0
greenColorValue=0

// Check statistical anomaly(BollingerBands) on price by volume(ForceIndex)
if fi >= bu then // here the BreakOut
 breakValue=1
 greenColorValue=255
elsif fi <= bd then // here the BreakDown
 breakValue=-1
 redColorValue=255
