for the tech or rather perl savvy, http://www.geniustrader.org/ has an open source framework to do GeniusTrader aims to be a full featured toolbox to create trading systems. Powerful systematic trading requires several things : * many indicators and corresponding signals * money management rules o deciding what is a reasonable amount of money to put on a single trade (to limit the risk associated to that trade) o combining different values within the portfolio (to limit the global risk) * flexibility to be able to test all combinations with the above items * backtesting system with analysis of results
It is a very cool (solid flexible straightforward) framework. I'd like to see it only gets better as freewares. The only problem that I feel is that it seems slow when being used to screen large amount of security data like S&P500.
This is awesome. I've been looking for something that I can really tweek myself. and it runs on linux!
thanks. i am a trader and perl guru. i will look into it myself. if i am too busy, i will hire a partime employee ($150 a month) for this job.
