Topic: PCF: Close outside of Bollinger Bands (20,2)
Posted: Saturday, December 3, 2011 10:02:57 AM
Sorry for the repeated posts in the same thread but I am working my way through this step by step.  I now have an indicator that flags a candlestick outside the BB, following a bar inside the bands.  If I want to add a condition that the next bar be inside the bands how would I change it?

In other words, the indicator I want to code is: a day within BB, followed by a day crossing out and finally with a day where open and close are both within the bands again.

Thanks for the help.

Okay, I think I got it.  For those wanting to use the above formula, just past the AND there is a "ABS(C1 - AVGC20.1" that requires a perenthesis after it.

For price crossing out of the bands (pasted here from Bruce L's post):

ABS(C - AVGC20) > 2 * SQR(ABS(C ^ 2 + C1 ^ 2 + C2 ^ 2 + C3 ^ 2 + C4 ^ 2 + C5 ^ 2 + C6 ^ 2 + C7 ^ 2 + C8 ^ 2 + C9 ^ 2 + C10 ^ 2 + C11 ^ 2 + C12 ^ 2 + C13 ^ 2 + C14 ^ 2 + C15 ^ 2 + C16 ^ 2 + C17 ^ 2 + C18 ^ 2 + C19 ^ 2 - 20 * AVGC20 ^ 2) / 19) AND ABS(C1 - AVGC20.1 <= 2 * SQR(ABS(C1 ^ 2 + C2 ^ 2 + C3 ^ 2 + C4 ^ 2 + C5 ^ 2 + C6 ^ 2 + C7 ^ 2 + C8 ^ 2 + C9 ^ 2 + C10 ^ 2 + C11 ^ 2 + C12 ^ 2 + C13 ^ 2 + C14 ^ 2 + C15 ^ 2 + C16 ^ 2 + C17 ^ 2 + C18 ^ 2 + C19 ^ 2 + C20 ^ 2 - 20 * AVGC20.1 ^ 2) / 19)

I am getting mismatched parenthesis error.  Can you see where to correct?  Thanks.
