Variable Moving Average, often abbreviated as VMA, is an Exponential Moving Average developed by Tushar S. Chande. VMA automatically adjusts its smoothing constant on the basis of Market Volatility .

Use this like other Moving Averages. I have added the following options that can be enabled via options page:
- Trend Direction Indication: Green = Up trend, Blue = Potential congestion, Red = down trend.
- Color bars based on Trend

List of my other indicators:

plot(vma, color=std?vmaC:black, linewidth=3, title="VMA")
barcolor(bc?vmaC:na) Close to the holey grail when combined with a MACD.
Would it be possible to add another Moving Average into the script like the Colored EMA SMA?
