Terabyte-scale market memory for trading agents. Propose a trade and see how similar trades performed throughout history under comparable market conditions.

Connect Agent to Leroy

A shorter path from idea to evidence.

Start with a trading idea. Replay it. Compare it. Add context. Then let the model decide whether it still deserves attention.

The point is knowing which ideas survived contact with the data.

See the strongest results so far today. Strategy names are hidden here.

Loading current paper-account results…

Each account starts with $100k, monitors 200 symbols, and deploys cash only when a buy signal triggers. Sale proceeds return to the shared account pool; symbols without signals remain cash. These are research simulations, not live broker returns or investment advice.
