Hi! Any suggestions for a free or cheap auto trading software I can use to test my stock strategies (mostly day trading and short term trading (a few days)) before I go Live real trading?
WealthLab, Ameritrade StrategyDesk, and CoolTrade all seem to offer this. I can't comment as to how good they are as I haven't used them. A number of lesser-known, third-party products/open source projects exist as well. If you Google <favorite broker name> and "back test", you'll get a lot of hits.
Try Cool-Trade...if you have an TDA Izone account, its free and it has a backtester. If you have an IB accounts, its only 50/month. I have four PCs running with Cool-Trade, and its great.
