I was looking at the original thread for this script and they said, they were having some issue with values. Did you figure it out?
It looks great to me. An example of this is SFIX from yesterday. It shows a DTR of $5.26.. That's accurate as the low from that day was 18.84 and the high was 24.10 (24.10 - 18.84 = 5.26) The percentage it outputs (which is what i would love to get in a scan) is 319% above it's ATR which is also accurate. Hope that helps.
