sorry thats the hurst exponent I am talking about, its a measure of the fractal nature of the series

This is a year late response but i just saw your posts. QuoteYou said you use signal analysis. My understanding is that methods like Fourier and Wavelet anlaysis are correlation based. The frequency coefficients (or scale for wavlets) are equivalent to correlations between the dataa and the underlying frequencies.When i said signal analysis i did not mean signal analysis that people use in academia. I created some other methods back in my old shop to do signal analysis. I almost never used correlation.Hefkey,How did your research go for hedging? Did you make any leads on it?
