Quote from JetFuel:
Reading back over the comments, it seems interesting to me that the comments about OptionsXpress involve "too expensive" and the comments about thinkorswim are almost always positive.
The reality is that thinkorswim is more expensive than OX in almost all cases - TOS only has an advantage if you're trading 5 or less contracts! (If you're an active trader, TOS only has an advantage at 4 or less contracts) Above 5 OX is less expensive.
It seems to me if you want a platform that is available most of the time with phone backup and have your own software OX is a pretty good choice.
If you're trading in the 5-20 contract range and trading more than 35 times a quarter, you qualify for OX's active trader discounts which get you to $1.25 per contract... still 25% more than IB, but no cancel fees, more reliability, and no add on fees if you need to pick up the phone... and much less expensive than TOS...
Am I missing something?
