This only works in a few markets and in certain situations. Changing the settings can give better or worse results for other markets. This is a good way to show off a good looking strategy, atleast in paper, with minimal effort involved in the making and usage. It can be made with the most minimal lines of code if needed to bring shame unto others. It only works in a few markets and who knows if it will actually rebound from the overbought or oversold levels but in case it doesn't I put in a time-based stop to exit in case of that worst case scenario. There's not much to it, good for trolling others, or serious business, you decide.
