Students often ask us about the differences between eSignal and TC2000, two platforms with charting tools that we highly recommend.
TC2000 Gold is what Ross used before switching to eSignal. The reason that he switched was because he found that TC2000 was not as reliable as he wanted--he had encountered a few instances where they didn't have charts for IPOs he wanted to trade. He highly recommends TC2000 for those who are hesitant to spend the extra money on eSignal, since eSignal Signature has many features that he simply doesn't use like Forex, futures, and options data, and so he's paying extra for unused features. One useful feature in eSignal that is missing in TC2000 is that chart data in eSignal dates as far back to when it first started trading, while TC2000's data range is more limited.
If you have access to Lesson 13 of the Original Day Trading Course, you can check out Ross' eSignal and TC2000 reviews if you want to hear it from him. At the timestamp of around 24:43 in the eSignal demo, he starts talking about TC2000 versus eSignal.
