Theory:

Stochastic oscillator is usually used on prices. But sometimes that produces much noise. Some filtering methods can be used (like this: Stochastic of Filtered Price).

This version:

This version adds an option to use averages for that purpose instead. The averages types that can be used:

• simple moving average(SMA)
• exponential moving average (EMA)
• smoothed moving average (SMMA)
• linear weighted moving average (LWMA)
  

Usage:

You can use the color change or some custom level crosses as signals.
