Commission and Charges
Of course, the last thing most people care about is what they really want: fees and commission. Commissions are normally charged on every single transaction you have had them carry out on your behalf; fees are a real mixed bag. Some charge on an all-inclusive flat fee basis for all trades while others divide it into a hierarchical system of charges based on the value of the quantity of trade. Finally, many brokers offer commission-free trading on stocks and ETFs which will be attractive both to active traders or cost-compression enthusiasts. Besides commissions, you might have to pay for some extras, such as:
Account maintenance fees. Some charge every month or annually just to keep the accounts open.
