I have been following the CFTC/COT data since the 1980s. I have NO clue as to what series is being drawn. There are MANY categories in the COT report, but none match this chart. The Large Traders is really the only short category that has grown dramatically, but they are up at 109,142 contracts this week.
Any hints as to what data series is being shown?
