Quote from Paulds11:
Didnt I already point out that BBs are problematic in defining strict entry and exits?..However they do add significant value in the way they impart high and low volatility transitions in price action more clearly... and we all know low volatility (Pinch) is superseded by a move or breakout in many markets..
I think thats valuable.. it increases confidence.. my trading success improved substantially on using them whilst learning through discretionary trades.... Granted ..though mechanically.. theres a problem.. but optioncoach had some interesting ideas no?
I don't use BB's but I have in the past.Quote from tortoise:
Curious: Why is it that the 1.5 Std Dev BB Band is so oftn paired with the 2x-AvgTR Keltner? Why not 2 Std Dev with 2x-AvgTR?
Is the assumption that two times the Average True Range = 1.5 Std Devs? If so, why? What am I missing here?
