Quote from Splat:
If you have an account with Tradestation beware. Look at your
subscription features regularly. They have a tendency to add
chargeable features to your account without asking you. I dont
know why they do this but I have had this happen to my account
several times.

Not right here splat.
They always send out an email and a letter to confirm options change.
Did have a software snafu over the weekend which was corrected Monday in which they added $20 for ECN books.
An emial was snet out stating this and how to fix it.

As far as I know I haven't had a problem with hidden charges, but as another poster mentioned, I've had BIG problems trying to get lowered commission rates. They aren't automatically transfered, which smacks of fraudulent advertising to me.
Anyway, good company - too damn expensive for what I do. Might leave for that reason only.
