I've read the advice given in the past on here to set your OR size and A values such that they complement your trading style (breakout or fading) and the logic of it makes sense to me. But that is for the levels you trade off. Is there any similar advice regarding the OR size and A values you use to construct your number line? I'm going back to the start of the year and calculating NL's for several instruments and am considering running the numbers on 2 or 3 diff OR sizes to see if one looks better than the others, so wondering if anyone had any tips.
Maybe Mav can get back to you on this... I think I know what your after. I found OR size ( I think you mean duration or time) is 45 minutes fro me.. I am not all that interested in real short term movements
