1) Let's say I am going to run an automated system in Tradestation. I would like to send orders to third-party brokers like IB instead of Tradestation brokerage. I'll take care of the coding of the trading system. But what about the automated part? After I have coded my trading system, what do I need to do to "automate it"? How can I tell Tradestation to send signals/orders to third-party firms like IB? Any clue? 2) I would like to hear more recent comments. How do you comment Tradestation as a brokerage firm? Good/bad? How good does it in running auto-system / executing auto-orders? Reliable/stable platform? Thanks for your responses.
