Cesar Alvarez did a backtest showing using not just SPY or QQQ being above their 200 day MA a good risk reducer, but being so 2,3,4,5 days straight is even better and with QQQ gives a higher return to boot.
Thanks for posting this. I have always used % above / below 200 day SMA feeling that simply counting days can lead to a false signal. e.g. Some bad news / large company intrigue can cause a bad week or two then reverse if the price is close to the line. I liked seeing the back testing and result. Especially for QQQ
For all values between 2 days and 10, there were higher CAGRs, lower MDDs for QQQ when you insist on more days in a row of price>MA200.
