This script creates a STDEV in a candle format so you can see the Change in a candle format and compare it with the actual price candle.
Is very similar to SMU RSI and SMU ROC. The interesting part is to see the full effect of traditional indicators in a candle format rather than a simple plot format. Very interesting view in SPX. There is a very big clue in the chart as STDEV changed since 2008. Can you figure it out?
Also, try this in lower time frame and you will be amazed how Algo kills volatility after each upside or downside. Fascinating
