I really like thinkorswim - the broker, the company, and the software platform - but you really need to watch out if you're planning to use their platform for charting futures: No, crude did not jump $2 in one minute this afternoon. Frequently, many futures charts (especially popular ones like ES) will stop working at the least opportune times e.g. market open or on big news. I know this isn't a problem on my end because I'll turn on the ShadowTrader feed to find he's experiencing the same thing, and I'll subsequently have the (excellent) support team at TOS confirm the problem. I currently keep only a small account in TOS consisting of some long-term investments, solely so I can use the TOS software for charting, however I think I may start looking for alternatives. I don't want to derail a thread created to share my concerns with TOS futures charting, but if anyone can recommend a software package that can chart futures with rock-solid reliability even in the busiest times, please feel free to send me a PM.
