that What-If did not cut it unfortunately. Variance does not match what I see on TWS. Raised it with the help desk and they could not provide a clear answer why this was the case. I was hopping for a simple overnight initial margin security by security report of some kind.
@tonyf Any reason that the IB TWS Margin Report doesn't fit your requirements? Performance & Reports, Other Reports, Margin. The report shows both Initial and Maintenance Margin for each security. KH
On reg T they tell you the req for the stock. I think they do it for options, but I don’t use reg t so I’m not sure. On portfolio margin they don’t tell you what your margin will be before you trade.
Only for Rules Based securities and Risk Based securities. Most of my holdings fall under the Portfolio Margin Details section - nothing there.
By doing a very deep portfolio massage I have managed to reduce my Initial margin significantly to a a blended 1.2x of maintenance margin now. But that process has been very manual. @def an overnight report would be terrific if your team can produce one. All the info is already visible on TWS.
