I have TDW but also just got Questrade, which is only $9.95 per trade BUT they do charge an ECN fee at times which can be a maximum of $50 per trade, but usually about $10 to $15 on SOME trades. For frequent traders I find it a very inexpensive on line broker. It takes a lot of time to set up the account, eg paper work, etc., but I believe it is worth the trouble. If you want any further info, please let me know.
