I'd like to use tradestation for research that observes COT data and Seasonals. Are these what's referred to as 'Plug-Ins'? if so, are they free or is there a monthly charge? In a scenario with tradestation being our broker, as long as 10 trades a month are made, the software and live data is free. Does this change once the COT plugin or Seasonal plugin is added? Are monthly fees charged per plugin? I'm currently using Genesis Trade Navigator, but I haven't found any overall positive feedback for their trading platform on this website. I'd love to hear from any trader currently using the trade navigator platform and have had positive results.
