What is the Corn COT report?

It is the weekly CFTC Commitments of Traders breakdown for Corn (CBOT): how many long and short futures contracts each group of large traders held as of the prior Tuesday, published the following Friday.

How do you read Corn net positioning?

Net position is long contracts minus short contracts for one trader group. A positive net means the group leans bullish; the weekly change matters more than the raw level.

What does the Corn COT index mean?

The COT index rescales a group's net position 0-100 against its own high and low over the chosen lookback. Above 80 is close to the most bullish that group has been; below 20 is close to the most bearish.

What is a bearish divergence in Corn?

A bearish divergence is Corn futures (front month) making new highs while the tracked trader group reduces its net long position — the rally is losing the sponsorship of the money that usually drives it.

Each group's current net position, rescaled 0–100 against its own high and low over the selected lookback. 0 = most bearish it has been in that window, 100 = most bullish. Unitless by design, so markets of very different sizes can be compared.
