Quote from Landis82:
What seems to be so difficult to understand about this form?
On Page #2, it states that:
"Every person who holds or controls a reportable position must file a CFTC Form 40, Statement of Reporting Trader."
Obviously, it depends on whether or not you are trading commodity or financial futures positions that are deemed to be at reportable limits, or if you have a financial interest of ten percent or more in futures or options accounts of the reporting trader.
This CFTC Form is pretty self-explanatory.
