I used the margin calculator at https://cpm.theocc.com/ to compare what the pm should be. It was about ten times that in my account so the order was rejected. I think IB want to have my picture on a driving license or passport before the account is approved. I will try again tomorrow.

What was your position you were trying to put on? Do you understand how PM works? You don't really need a PM calculator to figure it out. How could you be off by that much?

Why would you say you don't need a "portfolio margin calculator"? You are referring just to stock I assume?
For options the min. PM is based on the OCC's TIMS system which makes it, in my opinion, very difficult for the average trader to estimate. Add in IB's 5 standard deviation and volatility move and you end up with margins being changed on a daily basis and, depending on the situation, they may change very significantly from week to week.
