Interactive Brokers is the best broker for international trading by a significant margin. Interactive Brokers allows investors to access 125 exchanges in 31 countries across the globe. This reach is combined with a massive inventory of assets and 60 different order types to plan your entry and exit from a position. Investors can also fund their account in their domestic currency and IBKR will handle the conversion at market rates when you want to buy assets denominated in a non-domestic currency. And, if all that were not enough, the quality of trading tools available through Traders Workstation (TWS) make it easy to execute multi-layered trades across international borders. Interactive Brokers has won this category two years running, and there is no sign of that changing in the near future.
A full-service broker might charge you as much as $300 in fees to invest $10,000 in a mutual fund or up to $100 to invest that same amount in a stock. On the other hand, a discount broker typically charges no commissions for online trades and has a list of no-commission mutual funds. That means the cost difference alone is reason enough for new investors to use a discount brokerage firm.
ECN/Level 2 quotes: ECNs, or electronic communication networks, are computer-based systems that display the best available bid and ask quotes from multiple market participants and then automatically match and execute orders. Level 2 is a subscription-based service that provides real-time access to the Nasdaq order book composed of price quotes from market makers registering every Nasdaq-listed and OTC Bulletin Board security. Together, they can give you a sense of orders being executed in real time.
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.
