Fellow Forum Members,
I'm having no success in finding a Stochastic Oscillator that will play an audio alert WAV file of my choice anytime a red and green line crossover happens only in the areas above the 80 red line or below the 20 red line. In other words, only during an extreme overbought or oversold market. Once the crossover alert gets activated, one can expect with a high degree of certainty that a trend reversal is imminent.

Can anyone out there please help me track down a MQ4 file for such an awesome indicator? Thank you very much.
