Honest backtests on your own data.
Keep the code. Check the trades.
Manual. Replay the day, decide before the candle closes.
Step or play 1-minute to daily candles at 0.5x to maximum speed. Place market, limit and stop orders with a draggable stop and target. Nothing after the replay clock is ever shown.
- Write the context and your call before the trade. It is frozen at that clock.
- Long, short, wait or pass are all recorded, so a pass counts.
- Profit curve, expectancy, process versus outcome, and an evaluation-style account with drawdown rules.
Quant. Backtest the rules over years, then step through each trade.
Run rule-based strategies over your whole dataset with a real backtesting engine. Every run is isolated from your journal. Then walk each trade on the chart: before the fill, at the fill, after the exit.
- Prop-firm style accounts with trailing drawdown, so a curve is judged the way a funded account is.
- Slippage and the intrabar ambiguity rule are built in: a bar that touches stop and target is flagged, never guessed.
- Backtests run on your own computer, on the data you import.
AI Agent. Say the strategy. Get the Python. Test it on your data.
Describe a strategy in plain words, or import your own Python. Inspect the code, run it against your data, then examine the trades in Quant.
- Use your own OpenRouter key, or Codex CLI already installed on this computer.
- Strategies execute locally. Review AI-written Python before running it.
- Vibe-code, backtest, refine, repeat.
- static checks: one Strategy, one Config
- backtest on your own data
- saved to Quant as user strategy
