How the chart works

Historical twins, not a black-box call.

The engine stores BTC candle windows as vectors and retrieves the closest past shapes. You get the date, the analogue, and what actually followed. Direction on a short horizon is a coin flip — we say so on the chart.

  1. 01

    Encode the live window

    The last q candles become a shape: path, body, wicks. Same encoding for every historical bar.

  2. 02

    Retrieve neighbours

    HNSW search in Rust returns the closest past windows. No neural forecast in the headline path.

  3. 03

    Show what followed

    Each twin has a date and the forward move over f bars. Evidence you can inspect, not a LONG/SHORT badge.

Internal grading of the published band lives at /track-record — not the product, a scoreboard against a trivial baseline.
