The COT reports for futures-only Commitments of Traders and for Futures and Options Combined Commitments of Traders are collected on Tuesdays and published every Friday at 3:30 p.m. Eastern time. The raw data is available free of charge on the Commodity Futures Trading Commission (CFTC) website.
Use it to get a better understanding on which side the smart money (producers, commercials) are trading on.
The COT index ranges from 0 to 100%. Extreme values are areas below 25% and above 75%. When the index reaches 0% or 100%, it means that the market participant has the most extreme net short or net long position in the last 26 weeks. Readings below 25% are considered as a short sentiment and readings above 75% are considered long sentiment. However the COT index is not a timing tool. It only shows the overall market sentiment of the smart money in relation over the past 26 weeks.
You can change the period to calculate the index, as well as the style, which lines to show and if you want to highlight the extreme arias.
