I've 3 accounts with 3 different discount brokers. TDAmeritrade, ETrade, Scottrade.

TDAmeritrade - $9.99/trade (My Favorite)
You won’t be charged any maintenance fees and you’ll get low, flat-rate $9.99 commissions on internet equity trades no matter how many shares you buy. Clear and Simple.

ETrade - $9.95-$12.95/trade depending on amount of trading activity and account balance. (Read Power-ETrade)

Scottrade - Currently considering closing.

Stocks — Market and Limit Orders

For stocks priced under $1, add ½% of the principal value to the commissions shown. Some foreign and pink sheet stocks must be traded with broker assistance. Commissions are charged on a per order basis. Limit orders executed over multiple days and orders modified after a partial execution on the same day will be treated as separate orders for commission calculation purposes. A majority of orders must be executed online to qualify for the online commission rates. Scottrade receives compensation for certain equity and option orders as described more completely in our Order Routing and Execution page. Generally, this compensation will take the form of payment for order flow, profit sharing arrangements, liquidity rebates or possible trading profits if Scottrade executes the order as a principal. For non-online accounts, the commission for market and limit orders is the broker assisted rate plus .02 per share for stocks that are $1 and above.

Canadian Orders

Canadian orders cannot be placed online. Quotes given by brokers are typically in Canadian dollars, while orders are entered in U.S. Please clarify with your broker if you have any questions. Add in the Canadian floor brokerage fee if buying, or subtract if selling:

• Stocks under $10: .01 per share
• Stocks over $10: .015 per share
• Vancouver charges up to $.05 per share for odd lot orders.

The following is a schedule of what is considered a round lot on the Vancouver exchange:

Canadian exchange fees are charged in U.S. dollars. It is the client's responsibility to ask the broker if any additional Canadian fees will be applied prior to placing a trade.

When Scottrade acts as a principal, the bonds will be subject to a markup or markdown.

All commissions, fees and rates are subject to change without notice.
