Very nice spreadsheet; however, in REALITY, TOS commissions are $1.50 per contract with NO minimum ticket charge (and yes, they were $1.50 back in 2006, when the calculation above was made). So, TOS is, ACTUALLY, quite a bit CHEAPER than OptionVue with Interactive Brokers. Over 5 years, you would spend $2,745 MORE with OptionVue than with TOS. here is an updated spreadsheet based on the previous one by faldska: https://docs.google.com/spreadsheet/ccc?key=0Ahz5cJ_tvywJdFRBMUVwUkJDelBDZzV2VjRZNEdkc2c btw, I do NOT work for TOS
