I'm most interested in money flow for swing and position trading. I currently use TradeStation and want to know what others are using that doesn't have the sort of limitations I'm encountering. My biggest issues with TradeStation are the inability to receive T&S data, the lack of sub-second (microsecond or sequential count) timestamps and the lack of sub-penny price information. Would appreciate some pointers to data providers that could provide a tick data feed (live and historic; 6mos?) similar to these requirements. Thanks.
