Currently use Ensign with IB data feed. Thinking about switching to either Sierra or Ninja since they both support IB feed. Ensign has raised price and it still has issues with data refresh. Not the bargain it used to be. I would be very interested in anyone elses experince with these platforms. I mainly trade ES, NQ, and stocks. Don't do any automated stuff...yet. My charts are very simple...no indicators but I do use trendlines.
