A broker's commission is a fee charged by a broker for executing a trade on behalf of an investor. The commission is typically calculated as a percentage of the total trade value and can vary depending on the broker, the investment type, and the specific trade. For example, stock trades may have a different commission rate than options trades. Commission rates can also be impacted by factors such as the size of the trade, the frequency of trades, and the level of service provided by the broker. Some brokers may offer lower commission rates for high-volume traders or for clients who maintain a certain account balance. It is important for investors to be aware of the commission rates charged by their broker and to factor these fees into their investment decisions.

A broker's commission is a fee charged by a broker for facilitating trades on behalf of a client. This fee compensates the broker for executing buy or sell orders in financial markets like forex, stocks, or commodities.

The commission structure can vary depending on the type of broker and market. Some brokers charge a flat fee per trade, while others may calculate it as a percentage of the total trade value. In forex trading, brokers often earn through spreads—the difference between the buying (ask) and selling (bid) prices—rather than direct commissions. For stock trading, brokers may charge per share or per trade.

Ultimately, the commission affects the cost of trading and can influence a trader's profitability.
