It's a formula you know already - buy the dips (aka swing trading, aka mean reversion, aka 'buy low sell high').

The edge is in adding some filters which help you avoid catching falling knives. Then realize it's something that works over a large number of trades, and that individual trades like this mean absolutely nothing. Where you exit is very important also. You can do it yourself if you want to get some backtesting software and dedicate some time to it.
