Stochastic cross alert indicator

I've been looking for a stochastic indicator alarm which only signals when crosses occur, ignoring the overbought, and oversold zones.
can't seem to find one

any suggestion?

thanks

The Stochastic Cross Alert indicator draws a buy arrow on the chart when the indicator lines cross each other from below 20 back above (oversold readings). Similarly, a red sell arrow appears on the chart when the lines cross each other from above 80 back below (overbought readings).
