I've been with Optionshouse for several years. Originally they had a very low commission structure (including for options) and very low margin rates. I am not a heavy trader, but am classified as a professional trader, so they allowed me to use their service with delayed quotes in order to avoid professional data fees.
When they merged with Trademonster they promised grandfathered pricing, which they somewhat kept, except that a short while ago they rescinded on that promise where it comes to margin rates.
Now they announced that they are being bought by E*Trade (which has been around since Compuserve days for those interested in nostalgia), so I don't expect to retain the favorable option trading commissions I've enjoyed.
Looking for suggestions for alternatives.
Placetrade looks very good, but they don't open accounts in NY.
IB would be interesting, but not sure if they will allow me to use their platform with delayed quotes to avoid pro data fees.
