Hello and thanks in advance. I'm simply trying to compare two stocks % return over a given number of days to now and it looks like this study (PerformanceComp.efs) should do the trick but the results seem to be off. (I've checked the results by hand.) I would like to go back 100 trading days (or whatever) and be able to look at the chart on 5 or 15 minute intervals but when I do this I get different results. (The percentage return for each stock ends up at a different level even though the beginning and end prices should be the same.) That shouldn't happen since the percentage return from the beginning point to now has to be the same regardless of how I slice the time intervals. Any help would be appreciated. TNX.
