hey whatsup...i'm new to investing but i'm experienced with some advanced analytical techniques & have been working with S&P 500 data for about 2 years. anyone care to discuss their experience with software and analtical techniques? are there any modelers here? anyone using autoregressive techniques; maybe ARIMA, statespace modeling or even technical analyses in C++ or SAS? i'd be interested in hearing from other analysts, i've been in hiding for a while developing an automated trading system & basically want to discuss.
