PAPER TRADING · SIMULATED RESULTS ONLY

Turn your trading notes into rules.
Watch them trade — on paper.

Paste excerpts from a course or write your own rules. Ledger Sim extracts explicit entry, exit, risk, and invalidation rules, then runs them against real market data in simulation — so you can see how a strategy actually behaves before ever risking capital.

01

Save a strategy

Paste transcript excerpts or write manual rules. We extract entry, exit, risk, and invalidation rules you can edit.

02

Review explicit rules

Every rule is a plain-language statement with editable parameters — nothing runs until you approve it.

03

Run it in simulation

Activate a paper-trading run against real recent market data and see simulated trades, not real orders.
