You should expect this exposure fee to be assessed on any day other than a weekend. It was not assessed for a number of days in June due to closing price anomalies on the part of the OCC, from whose data is used in these computations.
In addition, the fee is not assessed upon expired contracts
Lastly, weâd note that there is no expectation or desire on our part for this fee to generate any meaningful level of revenue. Rather, it is intended to incent clients whose exposure is deemed excessive to adjust positions and/or increase collateral. Should you have any questions regarding the fee or believe that your account was assessed incorrectly, please call us and ask to speak to a member of the risk group.
Why not just increase margin requirements for contracts with excessive risk?
IB already has excessively high margin requirements for short futures options.
IB's overnight ES margin is $5406.25. IB's overnight margin for a short OTM ES put or call is $8890.
I would appreciate someone at IB explaining how a short OTM ES put or call will create a larger loss in a huge overnight move than the ES future.
I understand that after a huge move deep ITM options will lack liquidity and that volatility will expand in a downmove, but exactly how can the initial OTM option create a larger loss than the underlying contract?
