TOS is most definitely not suited to intraday futures trading. Intraday margins are way too high and they don't have a real DOM display. Also a quite limited selection of futures. In a fast market the charts will noticeably lag the quotes. Their customer service is not as good as it used to be. It seems they hold limit and stop orders too long on their servers making you late into the queue. Their realtime accounting is second rate. For example, they exclude commissions when showing profit and loss. They have some obvious software errors that they have not fixed for several years, such as incorrect dividend rate calculations on equities. (they can't figure out the difference between quarterly, semi-annual, and annual dividends.) If you leg into an option spread, once you have acquired the complete spread they may not compute the correct margin. In other words, they may have trouble computing your net option position. (Not necessarily a problem only with TOS.) You can always call the trading desk to get it straightened out. New traders should be aware that you can get rich quickly on paper by scalping on their paper trade platform. But be advised that their paper trade platform has a very poor fill algo giving you consistently unrealistic fills. I once wrote them about this but never received a response. I think they do it intentionally to give new traders a false idea of how easy it is to make money in intraday trading. They are very good on some other things. Their option analysis software, for example, is quite nice, and it may be worth opening an account just to have access to it. Their commissions may be higher in general than some other brokers but there is no charge for the data feed or the platform. However they seem to be fixated on adding bells and whistles to their platform, which I think are attractive to inexperienced traders but of little real value. Meanwhile their "DOM" display does not show the Depth Of the Market but only the size of the inside bid and offer. It seems that would be something you would want to attend to before adding another esoteric indicator.
