Stochastic divergence indicator with stochastic cross?

I'm looking for a a Stochastic divergence indicator which also uses zig-zag to mark highs and lows, and not to give the signal for the divergence until the Stochastic has crossed out of the overbought or oversold area.

Here is an example



Anyone know of this something like this which exists? or would anyone fancy having a crack at making one?

I've trade this strategy with moderate success, but i need to fine tune my money management. I'm lead to believe that professional traders who trade divergence use this exact same setup, so this indicator would prove profitable with the right money management.

This strategy is mentioned in the baby pips school website as being profitable
