At present, CFTC publishes the position data every Friday and Tuesday, which is 15:30 EST (JD.COM Zone 8 is 3 hours later than the US Zone 5/kloc-0, which is 4:30 am every Saturday). Position reports are divided into "futures only" and "futures and options". Generally speaking, job reports refer to the former. Of course, understanding the changes of option positions will also help us to track and analyze the trend of funds.
