Thanks a lot! Any result?

How is the API comparing IB?

IB claimed that my portfolio on TSLA would have loss when TSLA price dropped by 6.5%. Based on that they rejected my order to buy TSLA. I disagree and I think dropping price should bring me huge profit instead and my risk is on the up side. I asked them yesterday to give me more evidence. They...

did you try to increase mem allocation? it helps me a lot

I got reply from IB. They claimed there would be big loss if TSLA price down with vol up, and NVDA price up with vol down, which are contrary from my view. I'm still trying to get more information from them. In the mean while, is it legal that I post our conversation here?

Today I got margin call again. It was post expiry margin deficit. As I mentioned earlier, IB doesn't show the impact to post expiry margin from a trade until the order is executed. It make it even harder to reduce the deficit. I managed to reduce the deficit by 70% but I couldn't reduce it...
