To Winner :
Thanks for your encouragement !!
The Bolinger band settings are .........periods - 20
.........Standard deviation - 2.0
These are the common settings.
I have the book.......Bolinger on Bolinger Bands by John Bolinger. (not cheap).
The purpose of the additional BB on the 1 min chart is to try to detect extemes.
If we have a price that goes right thro the BB and even the 2.8 BB and, at the same time the MACD is turning around (we look carefully for that and make sure we see the turn)...........then we can be pretty sure we have an extreme point.
I hope to be able to illustrate this concept in more candlestick chart postings I am planning.
Hope this helps.
Kind Regards, Tymen Wortel, Perth, Western Australia.
