Hi all, Anybody had experience with TradeStation 's high frequency tick level market depth data capacity and performance? We need real-time market depth order book for 500+ stocks... at 1 second level... Will TradeStation and its API still be able to handle this? How about historical market depth order book (L2) data at 1 second level? How do I get these things from TradeStation... My buddy wants to switch to TradeStation and I think that's a huge amount of re-programming so I have to make sure it's all right... Thanks!
