The promise of commission-free ETFs has steered many index investors toward independent brokerages such as Questrade and Virtual Brokers. These deep discounters have a lot to offer, but before you sign on, make sure you understand the details of their pricing.
Orders at these brokerages may be subject to fees that originate with the exchanges and networks that match buyers and sellers. This includes the big boys such as the Toronto and New York Stock Exchanges, as well as a host of lesser-known electronic communication networks (ECNs) and alternative trading systems (ATSs). Though it’s not technically accurate, you’ll often hear all these costs lumped together as “ECN fees.”
ECN fees are applied on a per-share basis. They vary slightly depending on the brokerage and the specific exchange, but they’re always fractions of a cent. At Questrade, for example, the cost is $0.0035 on Canadian stocks and ETFs, while Virtual Brokers charges $0.0039.
