Assume you are an independent trader (not a member of a trading company) and you are a member of the NASDAQ.

Assume you tend to trade (buy or sell) an average of 100 shares of a stock each trade day (say a different stock each day). On average what would this indpendent trader have to pay in trading costs each day?

Thanks in advance for your help
