I am trying to create an alert that alerts me when the price is crossing the bollingerband (9 length,exponential) on either the upper and/or lower band. This is for forex pairs. I would also liek to ou tthat code into a scan if possble. The code that I have created with condition wized is below. Also, a screenshot of the price action set up im looking for. I want the alert when its eithere or.

bid() is greater than BollingerBands(“length” = 9, “average type” = “EXPONENTIAL”).”UpperBand” or bid() is less than BollingerBands(“length” = 9, “average type” = “EXPONENTIAL”).”LowerBand”

There is nothing for me to do there. What you have is already complete. Why did you post this question if you have already created the solution?

The only change I could suggest is to replace "is greater than" with "crosses above" and replace "is less than" with "crosses below".

Thank you Pete! I just wanted to make sure that there weren’t slight changes that could be made to improve it. It seems when I do ”crosses above” or ”crosses below” the condition wizard grays out and its says No historical values for BID. Also, it wont let me create alert. What shoud I do to fix that? Thank you CC

I have zero experience with Forex. Only thing I can suggest is to try using something other than Bid until you find something that works.
