I'm considering to switch from IB to TradeStation, but I want to make sure about the following first. Is there any other program comparable to EasyLanguage ? Can EasyLanguage be used without TradeStation, like if I have the intraday data on an Excel Sheet, would I be able to do backtesting on it with EasyLanguage ? Are EasyLanguage and the historical data free once you become a client of TradeStation ? My fund is somewhere around 7000$, it might be more by the time I decide to subscript to TradeStation's brokerage service, I think I meet the requirement for a daytrading Future account. The only thing I still hesitate about is the fees. It requires me to do 10 roundtrips a month. That wouldn't be a problem as I'm a daytrader, but as I have lost money quickly last couple months, I decide to move on to developping some consistent strategies, I want to take the time to test my strategies. Also, on IB, CME's data are free, but with TradeStation, it would be like 50$/month. However, so far, Tradestation seems to have the best feature around for backtesting. Please give me some advices. Thank you! Thank you!
