what pisses me off highly is that the exchanges throttle the data that is supposedly real time to retail. so you pay for real time but you don't get the same data that members get. remember the exchanges exist for the benefit of it's members and not to serve the public. keeping that in mind one can out maneuver the members, if you understand the antics they play.
yesterday i was watching a bracket trade and it was like someone flipped the lights off and back on and suddenly my trade was gone, lol. it was a wide ride yesterday on the emini sp and i know that there is manipulation going on there is no doubts. but you just have to work around it.
there was much discussion a few years back about eliminating the illegal real time fees in the first place they are public domain we all own that data. the thought was the elimination of fees would bring in more volume but as typical greed took over good sense and that is why people are working on a global exchange match up engine that would completely eliminate exchanges and brokers. every trader would become their own exchange, it's in the works.
