Hello, we sincerely apologize that the combined options trading is currently under optimization. Before the optimization is completed, you can currently place individual options orders, which will be automatically combined for you, or wait until there are no single-leg options positions in your account before attempting to submit a combined options trade. Once the optimization of combined options trading is completed, we will proactively contact and inform you.

How can we use combined strategies like this? First, close all option positions in the account, or naked sell calls or puts and combine them ourselves? Can the margin be the same? You sent me an email asking me to use it as a beta tester, and you also promoted combined strategies in the community, but it's so troublesome when trading. Are you kidding me?
