Just noticed Extra Fees....
It's been driving me nuts lately when my addition & subtraction of
option trades & commissions didn't jive with the Virtual Simulator
total cost per transaction. Finally today I noticed under "Account
Activity", a box to "Show Commissions & Regulatory Fees." I checked
the box & saw Fees of a few cents added to each option transaction
(SEC Fee & Options Regulatory Fee). Mystery solved. Once again, a good
lesson learned from the virtual simulator: In the real world - Ask
about ALL FEES associated with each trade.
