Good Morning, I am interested in knowing which brokers would the best to use, when trading between 9:30 to 9:45. I have been trading for a little over a year, and have been using scottrade and ameritrade. I have learned, they are not really suited for daytrading, really slow executions. I have waited 3 to 5 minutes after putting in the trade, just to know what price Im am at. This question has probably been on here before, but I would appreciate all responses. Thanks, Joey
