About GrainDecision
The problem
Grain markets generate a considerable amount of data every week: COT reports, USDA balances, fund positions, Euronext/CBOT spreads, live prices. This data exists. It is public. But it is scattered, technical, and rarely presented in a usable way for those who need it most: farmers, grain traders, cooperatives.
What GrainDecision does
GrainDecision centralises this data and transforms it into readable signals. Euronext COT, WASDE balances, spreads, market tightness indicator, live prices. Everything in one place, automatically updated, analysed using quantitative methods validated by backtesting.
Built for:
- Grain farmers (wheat, corn, rapeseed)
- Trading companies and cooperatives
- Agricultural commodity traders
- Businesses connected to agricultural markets
- Any operator making pricing decisions
Who I am
My name is Aziz Laaziz. An agronomic engineer by training, I worked in grain trading and price risk management for agricultural cooperatives. This experience led me to build analysis tools to rationalise grain marketing decisions.
GrainDecision is the public version of these tools, built to share this type of analysis with a wider audience of operators.
No generative AI, no forecasts. Verifiable data, documented quantitative methods, and a weekly update cycle.
