Introduction
The lab, the ledger, and how to take your strategies with you.
Chat·Backtest is a place to find out whether a trading idea would have worked before you risk anything on it. You describe the rules in plain English, the lab turns them into a precise specification, and the engine replays them against years of historical market data in seconds. When a strategy is worth defending, you can deploy it to the ledger — a public forward test that scores it on data that did not exist when it was built.

How the docs are organized
- Getting started walks through your first backtest, how to read the results honestly, and how credits meter usage.
- The Lab covers building by chat, the markets and timeframes available to test on, and the strategy spec itself.
- The Ledger explains forward testing: frozen specs, append-only records, and why losers stay on the board.
- Your arsenal is about leaving with something useful — Pine Script and Python exports, and trading a strategy manually from its plain-English rules.
