Formula for BreakOut of Bollinger Bands in Daily and Weekly

I was looking for a formula that would give me the Break Outs of Bollingeur Bands (BB) in Daily(D) and Weekly(W). Finding nothing to my liking, I wrote one.

In an upward wave, we often have several BB Brake Outs.

To overcome this problem I added the Stockastic Crossing to my formula


On a daily(D) graph, we have the result:

The BB BreakOut in daily: function BrOutBb(P) in orange

And the BB BreakOut in weeklyk: BrOutBb_W(15) in blue and orange on a TF weekly(W)

The function BrOutBb(P)- orange gives me the BrOutdeBB on the Time Frame(TF) that we have on the screen (D or W) and I like their result. Whether it’s a daily(D) or a weekly(W).

The BrOutBbW-in blue, on the TF daily is very disappointing.

I am open to any comments to do better.
