I am looking for a new broker for trading equity index futures. My main requirements are stability, accurate timely quotes and executions, low day trading margins, low fixed monthly expenses, and low commissions. Pretty much in that order. I would also want to be able to paper trade to familiarize myself with the platform, and I would like to be able to back test strategies without knowing Python, C#, C++, etc. if possible. Basic charts would also be helpful - especially a pair chart of two instruments/indexes. I like IB's TWS classic using hot keys. I don't need anything fancy just something stable and fast that allows me to adjust orders quickly before they are sent (and after on occasion). At this point, I don't want to deal with IB's high day trading margins. I am leaning towards AMP or Ninja Trader. Which would you recommend? Or, is there something better for what I need? Thanks for any input.
