Bruce says there is an Error....

Hi:
This produces a signal when the price goes below the bottom Bollinger Band and then is followed by the next green candle.  I've used it successfully as a buy signal & need help making it now do the opposite (price goes above top Bollinger Band followed by next red candle).  Thanks, Fred

Let's start by shortening that a bit using newer syntax.

C > O AND (XDOWN(L1, BBBOT(2, 20, 1)) OR (C1 <= O1 AND XDOWN(L2, BBBOT(2, 20, 2))) OR (C1 <= O1 AND C2 <= O2 AND XDOWN(L3, BBBOT(2, 20, 3))))

That should make inverting it a bit easier.

C < O AND (XUP(H1, BBTOP(2, 20, 1)) OR (C1 >= O1 AND XUP(H2, BBTOP(2, 20, 2))) OR (C1 >= O1 AND C2 >= O2 AND XUP(H3, BBTOP(2, 20, 3))))

If the issue is actually the copy and paste, try copying the formula into a text editor (so something like Notepad and not a word processor such as Word). Then copy and paste from the text editor into TC2000.

Bruce There is an error for this too..

Bruce, I copied and paste to a notepad and still there is still error

Bruce I tried again, now it works

Thanks

You're welcome.
