Hello All, I am new to the future trading and still in the middle of setting up my trading account. I use IB for my stock and option trading. I plan to continue use it for my future trading if it is good enough. I am also planning to get the Ninja trader. On the other hand, some people mentioned that the Zen-fire data feed is the fastest and best. I am just wondering whether Zen-fire is absolutely necessary for scalping YM/ES? Is the IB data feed for emini good enough? Also heard that AMP future and Mirus both carry Zen-fire + Ninja trader but they are expensive. Anyone has experience with them? Thanks a lot.
