FAQs

What is AI for oil trading?
AI for oil trading refers to software that reads live market data, applies trading logic, and produces analysis a trader can act on. It spans three levels: assistants that retrieve data, agents that run multi-step analysis, and decision engines that hold a persistent view of a trader’s book and market. Most tools sold as AI today sit at the first level. Leonidas AI works at the third level.
What is the difference between an AI assistant, an AI agent and an AI decision-making engine in commodity trading?
An assistant answers a question from data it already has. An agent runs a sequence of steps, calling tools and data sources to build an answer. A decision engine does both, then retains context across sessions: your positions, your products, your rules, and what it has learned from your feedback. The distinction matters because only the third improves with use. Leonidas AI is currently the only AI decision-making engine.
Can AI actually make trading decisions?
No. AI systems in physical commodity trading support decisions, they do not take them. Autonomous execution remains constrained by regulation, market speed, and the judgement complex physical trades require. The realistic gain is compression of the analysis cycle, from hours to minutes, and the simultaneous real-time assessment of multiple scenarios, so the trader reaches a view faster with more of the picture in front of them.
What can AI do for a physical oil trading desk that a spreadsheet cannot?
A spreadsheet holds one trader’s logic and dies when they leave. AI systems built on shared market logic hold that reasoning centrally, update it continuously against live prices and flows, and make it available to the whole desk. The analysis survives staff turnover.
Why do general-purpose AI models struggle with commodity market questions?
Foundation models are trained on public text. Refined product arb economics, physical premiums, blend margins and freight route pricing are largely absent from that corpus, and the live prices are proprietary. A general model asked about a gasoline arb will produce fluent reasoning on the wrong numbers. A general also lacks the oversight of human expert analysts. The gap is data, as well as domain logic and human expert oversight.
What should a trading desk ask an AI vendor before buying?
Where does the price data come from and is it licensed for this use; which markets are covered and which are not; can it show its working and cite its sources; does it retain our context and who owns it; can it run inside our security model; and what happens to the analysis when the vendor changes model provider.
Is AI in commodity trading regulated?
There is no commodity-specific AI regulation governing decision-support tools today. Firms are typically governing them under existing model risk, market conduct and data licensing frameworks. The binding constraints in practice are data redistribution rights and internal model validation, not AI-specific law.
