@Hredot, I'm getting the following error message:
Error 014: ATR needs LookBack 520 > 480
The script runs and it gets a 26% CAGR, but this error makes it a bit scary to put it live
It appears a couple of times, the script I'm running is the v1.1 without any change (but it happened also in v1.0).
(Also it gave a warning about VOO not having the first 175 bars, but that warning disappears using a StartDate=2011)
