If what you're saying is correct, the first 122 should have been terminated directly due to insufficient margin, and I wouldn’t say a word. But the first 122 wasn’t terminated, it dropped to 118, rebounded, and then the second 122 got terminated. This is either an issue with your termination judgment, or you’re confusing maintenance margin with additional margin. Your reply is already very professional. Considering the actual situation: Can water falling from the sky kill someone? No need for such a complicated explanation— just having been in the rain is enough. The first 122 said the margin was sufficient, the second 122 said the margin was insufficient. No matter how complex the explanation, it doesn’t align with common sense or the basic consensus among traders.
