Yea sorry thought it was pretty obvious what I meant. Thanks for the Response Robert. I am strongly considering using light speed but what's stopping me is the commissions for small share size is rather confusing. If I buy 100 shares of xyz and then sell 50 shares then 25 and another 25 shares...
I want to trade the first 30 seconds of the open and I am currently using think or swim which I found out the hard way not to do that. What brokers are best during this time with no lag?
