Quote from SteveH:
TSIM+ is a free front-end to IB and can do automated trading through writing commands to a known text file:

You could have your signals generated by TradeStation, write the orders to a text fiel and TSIM+ can execute them through the IB TWS. Give it a try with your IB paper trading account and see if you like it.
