Oscillator Moving Average (OsMA)

This code for Oscillator of Moving Averages (OsMA) is based on MACD 4C indicator code published by vkno422. Many thanks to vkno422. I have borrowed the concept of 4 colours which I find very useful.

For those who are not familiar with OsMA, it is histogram of difference between MACD (oscillator) and its MA (signal line). The zero line cross over of this indicator is used in many strategies.

This version includes MACD & its signal line together with OsMA histogram. I have programmed flexibility for switching OFF/ON individual indicator components as well as changing the periods for various moving averages.

I am dedicating this indicator to the TV trading community hoping that people will find it useful.
