I have been using this Tradestation PlugIn for 2 months to day trade pairs and have had really great results. Definitely not the holy grail of trading, but it supplies a logical, easy to understand trading system for pair trading. It has real time alerts to get you in trades as well as out of them. Also, the developer is great and answers all of your questions in a couple hours. Its the best $50 I have ever spent! www.daytradepairs.com
Just wonder if there is broker / platform that has an edge for executing pair trade orders? Thank you for your insights Berbo
