In my experimentation to add some sort of hedging to trades, I stumbled on the Martingale roulette betting strategy. If it works in the casino, why not here?
The principle is simple: If you lose a trade, immediately go the opposite direction and double your bet.
In this case, we're just applying a multiplier.
The strategy is a simple EMA crossover - defaulted to my favorite periods 8 and 62.
Enjoy :) I'll make a new one that's contained in a function, so you can simply implement it in your own strategy and have it monitor winning/losing trades automatically.
