PTF PRO calls trade signals onscreen and by email, so you can trade them as they arise through any broker you choose. Our client uses a very wide variety of brokers. You can only semi-autotrade them through IB however.
If you don't use IB for data, you have two other feeds available:
1. Yahoo Finance free feed: delayed intraday data 5-15 minutes, depending on the exchange and instrument, and 10 years free historic data. Most clients find this feed is adequate for our trading system as we are undertaking multi-day swing trades and second-by-second price monitoring and execution are not critical
2. IQFeed: this is an expensive third party subscription but provides high quality real-time and historic data on USA/TSX/LSE stocks, futures, options and FX. Most professional clients use this feed or IB.
