I have a PM account, and I noticed that going long some options had over a 100% margin requirement. In some cases, buying an option had a 400% maintenance margin requirement. Am I missing something? Per my understanding, it is impossible to lose more than the amount of the option if I am long, so the maintenance margin should be at most 100%. What makes this weirder is that if these long options increased in value, because the maintenance margin requirement is over 100%, my margin buffer would actually decrease, possibly causing me to get liquidated. I chatted with support, but they were unhelpful. I am not doing any complex option strategies; I am buying calls and puts to predict price direction. Am I missing something with my logic? Is this a known issue with IBKR? I have heard of more complex option strategies having unreasonable margin requirements, but I am not doing those, and it seems like it should be easy to cap the maintenance margin for long options to 100% of their value.
