What does your margin account have in it at the end of each day? The risk-free rate is 2.60% per annum with daily compounding (assume 260 day year). If there is a margin call, note that there is a margin call and record that you deposit the necessary money into the account as a separate transaction instantaneously, i.e. if on 10/2 you needed to put in $1,500 at the end of the day you should show a deposit of $1,500 on 10/2 after the close of the day.
