Bollinger Band Width Scan

Optuma Scripting
1

Hi,

I’m trying to scan for when the current Bollinger Band Width is less than or equal to the lowest Bollinger Band Width for 120 bars with this script but I am not getting the correct result.

BBW(BARS=120) <= LOWESTLOW(BBW(BARS=120), BARS=120)

Thanks,

Tim

Hi Tim,

Using your formula I get 14 for the ASX 200 today with their lowest BBW in 120 days, and they all look correct (the red histogram is the 120 day BBW for the last 120 days, along with the red Show Bar arrows). Make sure that the tools and timeframe of the chart match the settings for the formula, and post an example if you think the results are incorrect. Thanks!
