1.Use standard Bollinger Bands ,that is,bb(s,20,2).
2.Use ema-2HIGH and ema2-LOW to outline the body of the worm.
3.If the body comes out of bands & re-enters ,then make an ENTRY.
4.The EXIT is, if body comes out the band,of the other colour.
5.In case of extreme Bullishness/extreme Bearishness another
pair is used pertaining to BB(20,1).
I have deleted BB(20,1) since ATR < 80points and to maintain simplicity,
otherwise another sell at 1415hrs can be spotted.
