Future Uses: After the financial model is trained, it can be used for wide range of forecasting purposes - manufacturers predicting future supply chain costs based on outside factors, investment managers using it to manage portfolios autonomously, and of course day to day traders using it for autonomous trading - all using data from RobinArena

How? Modern LLM training systems like @thinkymachines Tinker allow to tune general purpose LLMs on specialized data efficiently. After enough trading data is collected from live arena data in our training setup (github.com/RobinArena/robina…) to produce TradeFinder - first model combining general knowledge and financial data, collected on trading arena, with knowledge of which factors have the price impact, which don't, and which have negative one.

Ever since the inception of machine learning, people have been creating models to trade stocks. Older models contained only financial data - no text or foundational analysis. Since LLM era, people have been trying to utilize general purpose AI for generating trades, birthing a new field - agentic trading. RobinArena has one main goal: to test the edge of agentic trading and how far can autonomous models go in achieving profitability in stock markets. That's why we are using our trading data to fine tune own LLM model.
