I'm trying to make a filter to find a chart pattern I like when I look on yahoo. On Yahoo, I use ATR Bands. The ATR, 21 days, based on close, shifted 3 units above and below the close. I then want the upper limit to be above the upper BB, 20 days and 2 deviations. And lower ATR value above the lower BB. My issue is that I am having trouble with the first line. Today March 22, yahoo shows for PANW the upper ATR amount over the upper BB but my filter is saying that is not true. The second line to qualify the lower band appears to be working.
I should add that when I use the debug filter option and type in PANW, it is only the one line in question that does not meet the criteria. I also am not able to have all the lines draw on the chart to show me what StockFetcher says the values are and compare to Yahoo.
ATR(21)*3 + close > upper bollinger band(20,2)
and ATR(21)*3 - close > lower bollinger band(20,2)and close > 7.00
and close > weekly upper bollinger band(20,2) 26 weeks ago
and weekly average volume(30) > 3000000
and market is not otcbb
and market is not etf
and close is less than 25% below close 52 week high
Any thoughts or help? I don't know how to attach images to show my issue.

Here is the filter you were attempting:
However, your methodology is flawed in trying to fit ATR(21) * 3 inside Bollinger Bands. Look at the individual calculations on PANW:

You are probably going to have create a couple of variables using SF's Set command as you have to many math operations in your first line.
Try adding these 4 lines to the end of your filter so you can get an idea of what your issue is:
apply to symlist(panw,tsla)
add column ATR(21)*3 + close
add column 3 multiplied by ATR(21)
add column close plus 3 multiplied by ATR(21)
