Hi - great question. At just $100/month, esignal is a "must have" imho for day trading; I wouldn't trade without it. Quotetracker is great to get started with, and was what I used (with Datek as my broker) back in the late 90's. I don't know of any other chart provider that has a complete tape like esignal does, which is one of many reasons I really like the platform. Besides, day trading requires a $25K+ account, so it's mostly for if you have a lot of $$ to trade with, so the esignal fee is small compared to trade sizes etc..

Traders don't need the tape for swing trading, though, so quotetracker (and the free stockcharts.com and bigcharts.com) are great tools for swing trading, for those who don't need time/sales.
