I suggest you first indicate what type of volatility you are looking for.
As a daytrader, I measure volatility in terms of # of ticks per day. That's all that matters to me.
I am sure this would change if I were a swing trader.
How would you like to measure volatility?
Apologies that my post wasn't complete. I'm basically looking for the historical volatility based on historical data. Something like:
Let the continous compounded return be:
u = ln ( S(i) / S(i-1) )
where S is the stock price and i is the interval.
I'm looking for the following:
Stdev = sqrt ( (1/n-1) * Sum ( u(i) - u(mean)^2 )
Or in other words: Seeking Stdev based on countinous compounded returns for the YM, ES, ER2, etc...
Thanks
