DislikedHi marengo, I coudn't dercypt alphaomega's messages in every detail either, but as an algo-trader, they gave me some valuable hints for my search for statistical edges. I would like to comment two of your statements: {quote} At least for Forex, my statistical evaluations and tests tell me, that mean reversion strategies mostly have a better edge than trend following ones. It seems, that the old economic rule "low prices attract buyers and high prices attract sellers" is still valid in the long run. {quote} I coudn't find any edge until...Ignored

As a proof of my word, look at USDCAD. The fair value is 1.34, but according to volatility and time fair value can change a little up/down. At least here 100 pips can be grabbed.

Cheers

And this leads to that if someone can't identify the worth/value, how someone know where the mean is?!
