In the recent a few months, I suffered from margin call almost every trading day. Although from my point of view my portfolio is hedged well and I tried to reduce the margin as much as I could before the eod (quite often with the "help" from IB's forcing liquidation), the margin would still explode overnight and in the next morning I would see my account was with margin deficit again, from 20% ~ 60% over my total equity. Then I was given 10 minutes to fix the problem, which was often not successful because my attempted order was often rejected because IB think such order would cause margin deficit increase. And often the liquidation would kick in and I have to spend another a few hours to clean up the mess caused by the liquidation. Some times I couldn't fix it well - the market bounced back right after IB liquidated my position at a very bad price. In the Friday it would be even harder because there would be an additional post expiry margin deficit. I have no way to see the impact to such margin from the order at all, until the order was actually executed.
I composed several tickets to IB CS but so far I didn't get good answer. They usually just replied with generic information like what margin call is or why there would be liquidation when there was margin deficit. They would not disclose the details on how they calculate the margins, only saying it is their portfolio or risk based margin. BTW the link in their page to the "OCC's published list of Product Groups and Offset Parameters" is dead https://www.interactivebrokers.co.u...ex=us&rgt=1&rsk=0&pm=1&rst=101004010808010801
Anyone has the similar experience here? Can you advise how would you deal with such annoyance?
IB have excessive margin anyway which can become variable at times, brokers like AMP are better for this type of thing if you are trading close to the edge, there are ways to offset this problem but I'm not sure the architects will like me telling non-accredited how, sorry about that.
