Beginner question. As I understand it (vaguely), the COT report contains information on activities (eg. long/short position held) for specific futures contracts. Take, for instance, COT for 13874A, the corresponding futures contracts would be the ES (E-Mini S&P 500) future contract.
Now, what about 097741? Which are the corresponding futures contract? 6J, J7(e-mini JPY/USD), MJY(Micro JPY/USD)? Or all?
