Most stock trading activities are done through an intermediary called a broker. Brokers, who take and execute orders from the investors, can also offer investment advices and analyses to their clients. Such brokers are called full-service brokers and they charge a relatively high commission. The types of brokers that do not offer investment advices to their clients are called discount brokers. Investors who wish to save more money usually hire discount brokers because they charge less commission.
Online trading and broker-assisted trading are two of the most commonly offered services by brokers. There are some brokers who use an Interactive Voice Response System for placing orders via telephones and a Wireless Trading System for making orders via web-enabled cellular phones or other handheld devices.
There are some brokers who use their own proprietary software for placing online orders while some give their website passwords for accessing order departments. Brokers allow their clients to track the stock market movements by offering a variety of charting options. The analysis software provided by brokers may be included in their services either for free or for an extra fee.
