Hello, how are you? I'm more battered than a frog in a puddle.

Anyway, as the song says, I will resist.

I have a request. I learned to make futures out of courage, not just to be rich, but to be comfortable and if I want to buy a chocolate I don't have to think twice. Well, that's an illustration. Well, now to the point. Did I learn? Did I learn? Mmm, I don't think so much, that's why things are going the way they are. Well, what I wanted to ask of those who can and know what the difference is between the crossed margin and the isolated margin, and please, which one do you recommend?

Thank you very much.
