Numerous people have asked for an alternative to Tradestation or something that offers similar capabilities. I haven't tried it but StockWatch Pro , www.crontech.com ,claims to have at least some of these features. Anyone tried it?
Amibroker is going to implement intraday backtesting and realtime services by March 2002, I believe. They are quickly catching up with Tradestation. http://www.amibroker.com
