I daytrade the ES one or two dozen times a day for a minute to 10 minutes holding times. I use Tradestation. I'm manual, not automated. I have Time Warner Cable, standard service 15 mbps for $44.99. They have 3 faster tiers, with 50 mbps at $74.99 being the fastest. The upcharge is not a lot, but I don't like paying for things for no reason. Will upgrading my internet speed make any noticeable difference in Tradestation's responsiveness? Thanks.
