AZ Column Color

This indicator is based on ema cross-over (12,26).
In Thailand, the ema 12,26 Cross over is well known as the CDC-ACTION ZONE indicator.
.
The definition of a bullish trend in this indicator is when the fast ema crosses up the slow ema .
The definition of a bearish trend is when the fast ema crosses down the slow ema .
.
When fast ema is over slow ema the column will show in a green column and when fast ema is below slow ema the column will show in a red column.

I have made this indicator for use with CDC-ACTION ZONE.
