let's say you use SMA(20) as your support/resistance line. Would it be better to chart premarket or from previous close? For example, if i'm using SMA(20) on a 3 min chart, when the market opens, the SMA(20) will include the 1 hr premarket if i chart premarket or the last hr of the previous day.
sssiiiiiggggghhhhhh if only I had me when I was young, to counsel me NO it is best not to use MAs at all, you see my young starter uper, by switching to higher timeframe MAs you are not getting rid of your whipsaws you are simply slowing down the rate of signals thus making it appear that you are using better signals so it will take you 6 months to blow up instead of 2 months but if you really really want to use MAs then don't use it when they are based on pre open data or previous day data simply hide the pre open data and let your MAs develop minute after minute
