Fully agree. Believe we're over $24k for 1 ES now...Man, IB you need to lower your margin requirement. Yours is the highest of everyone out there.
On the one hand I understand them, but on the other hand it can also backfire:
First day they increased them, I overlooked it (wasn't aware) and was writing strangles on ES that I planned to cover when we would come 50 points from my strikes. Relatively safe strategy I thought, as I did not intend to write more than I could cover. So when we hit the point I had to cover, I found out I didn't have sufficient margin lol. Covered the part I could and sold some at a loss, so no big deal, but still, had they not increased their margins, I would have had less risk.
Anyway, now I know, so will be even more careful not to get close to their limits, but it's annoying.
