what those exams about? about regulations? I learned my hard lesson today. I was fined by CME $2000 with violation of message volume ratio. I traded Globex product ZB, 30-T. I never paid any attention to those messages. I created too many messages, but just traded not frequently. but this morning I received notice of this fine. I am surprised. also i noticed option order cancellation fee, cancellation fee is acceptable, but sum up, it kills you! who will receive cancellation fee, to me it is totally unfair. plus PDT rule, that hurts me long time ago. why those guys have some stuff there, that makes small account traders unfair! are those exams about this kind of things? if so, I get to take a real look at them.
