I've been with IB and I am satisfied. However, I wish to open an account for long term swing trades using some funds that are not mine. The account will be funded with 30K. My strategies will be primarily selling options/covered writes and may involve using futures options. I will incur inactivity/data fees if I go with IB and I am trying to analyze the lowest cost broker to use for this account. I am considering IB. Any suggestions to help me in my research?
