I trade stocks and ETFs off a 1 minute chart. Default setting for ParabolicSAR is 0.02 / 0.2 What i want to accomplish is make ParabolicSAR chart (on my 1 minute chart) exactly as it would, if i were running a 3 minute chart. Logic being, that in general i now use a second window, running 3 minute chart with ParabolicSAR at 0.02 / 0.2 and it serves as my trend identification. Said another way, I need to somehow adjust the 1 minute chart setting to show same results I'd get on 3 minute. I bet some of you math wizards will know exactly how? Thanks in advance!
