How we find the twin
We embed NIO's recent daily chart into a 256-dimension shape vector and search millions of historical chart windows for the nearest match by shape, then re-score the finalists on the exact window shown so the lines actually overlap. The match is amplitude-aware, so it's a real twin — not just "both went up."
