Watch an indicator repaint — live

Synthetic price series (seeded, deterministic — not market data) · same bars on both panels · the only difference is discipline

Both panels run the same pivot logic on the same bars. The left panel does what many published indicators do: it draws the latest swing immediately, then quietly moves it when price disagrees. The right panel does what our engine does: it waits until a pivot is confirmed by closed bars, draws it late, and never touches it again. Press play and watch the left marker wander.

bars played: 0 · left marker revisions: 0 · right: 0 by construction

"Instant" pivots — the repainting kind

Closed-bar pivots — what our engine ships

This is why a screenshot of a repainting indicator always looks brilliant: by the time you look, every wrong marker has been erased. The only honest test is closed bars plus an append-only log — which is exactly what our public ledger is.

One honest caveat the guides skip

"Test it in Bar Replay" is the standard advice for catching repainting — but replay feeds only closed bars, so it cannot reproduce the historical-vs-realtime divergence that causes much real-world repainting. Replay catches the crude cases; only watching an indicator live across bar closes — or an append-only log — catches the rest. That is why our evidence standard is the timestamped ledger, not a replay screenshot.

The series above is generated in your browser from a fixed seed — everyone sees the same bars. No market data involved.
