Interactive Brokers (IBKR) earns this award due to its wealth of tools for sophisticated investors and its wide pool of assets and markets. The firm makes a point of connecting to as many electronic exchanges as possible. You can trade equities, options, and futures around the world and around the clock. Interactive Brokers’ order execution engine stays on top of changes in market conditions to re-route all or parts of your order to achieve optimal execution, attain price improvement, and maximize any possible rebate. The order routing algorithms seek out a speedy execution and can access hidden institutional order flows (dark pools) to execute large block orders. The wide array of order types include a variety of algorithms as well as conditional orders such as one-cancels-another and one-triggers-another. You can also set up conditional orders based on price, volume, daily P&L, margin cushion, number of shortable shares available, rebate available from the trading venue, and other factors.

A broker is simply a licensed person through whom you can buy and sell these stocks. When you use an online platform, it essentially acts as an online broker. If someone wants to buy any product, he can contact a brokerage service. They would place an order and let him know the market price of the product. If the investor is interested, they would include a commission for themselves and process the order forward. If the user wishes to buy stock, the broker would forward his order to a stock exchange, which would approximately take 3 days to complete including the money exchange between the broker and the investor.
