After reading about how volatility (price movement) can impact a traders results, I had an epiphany. It might be worthwhile to trade the most volatile contracts, since trading profits come directly from price movement.

I've been researching how to program a 20 day historical volatility indicator in easylangauge.

So far, the base formula would look like:

code:
StdDev( Log( average( (c/ c[1]) , 20 ) ) ) * SquareRoot(365) * 100

This seems like it would yield volatility as a percentage measurment so that one could compare how volatile one contract is to another.

Is my thinking incorrect?

For comparison purposes it makes more sense to just use the n day high/low range as a percent.

(n day high - n day low)/(n day high + n day low) * 200

if you want to push it, do an ATR of H and L.

(Average(atr,n)/average(c,n))*100

This seems correct. I'll try this when i get home. My original formula that I copied from some site doesn't give me a consistent result that lets me compare contracts.
