Like most services, neither TD Ameritrade nor Fidelity charge trading fees or commissions for their platforms. The fee structure for both TD Ameritrade and Fidelity is largely similar.

For example, a brokerage might charge you for making deposits into your brokerage account or taking money out.

Non-Trading/Other Fees – Any form of fee for trading on this platform not covered above. Inactivity Fees – Any fees that the broker charges you for not trading, such as if it charges you for keeping money in a brokerage account. Trading Commissions – This is when a broker will charge you a percentage based on the volume or value of each trade. This can come in the form of a flat fee, or more often the broker will charge you what’s known as the “spread.” This is the difference, if any, between the buying and the selling price of an asset. Trading Fees – Any form of fee attached to each trade that you make. There are largely four types of fees to look out for in a trading platform: If you’re looking for a trading platform that will give you access to all mainstream asset classes and a broad base of data with which to invest, either of these services will work for you.
