Learning Day Trading

What is the best online platform for trading stock options?

I'm currently with sharebuilder because they didn't require a minimum... I've since gotten heavily invested into stock trading/option trading... I don't believe this is the best site for trading options, because I cannot find some of the quote symbols I find on other sites. Let me know.

1. Scottrade
2. InteractiveBrokers.com is popular with options traders. Its commissions are also considered to be very low in the industry. If you are looking for Strategies Analysis, sites such as http://www.optionwin.com (scanning, analysis, charting) or http://biz.yahoo.com/opt/ (basic strategies) can help.
3. If you want a cheaper alternative to Sharebuilder that also does not require minimums, you should check out Firstrade http://www.firstrade.com/
4. My experience is that thinkorswim.com provides the best platform for trading options.
