Another way to look at red days is to directly connect it to the RSI. Before any run we want the RSI as low as possible. Friday's red day helped lower it slightly. Too high signals an overbought stock and we don't want that. As long as the company is progressing forward, red days are simply reset days for the RSI. Although technically anything under 70 is good, I don't like to play it that close. Simply put, the lower the better. It takes time to learn that individial red days don't always mean "bad". Could you imagine a stock that started at .0001 and went green every day for two years? try to find one stock in the entire history of the market that had green days consecutively for two years and I'll give you $1 million. Believe me , I'm not sweating.
