Chart Echo is a chart-first web app that finds visually similar historical chart patterns — 'fractals' — across stocks and crypto. It overlays past matches on your current chart and projects how they continued, so you can study historical precedent.

What can I do with it?

Search for similar historical chart windows, overlay the matches on the live chart, view a projected continuation cone, save favourites and collections, build chart workspaces, and export or share charts and animated Story GIFs.

Which markets does it cover?

Stocks and crypto, across multiple timeframes including daily and intraday.

You can search and inspect charts without signing in. A Premium subscription unlocks Pro Mode, premium timeframes, animated Story GIF export, and fractal workspaces.

Is Chart Echo financial advice?

No. Chart Echo surfaces historical chart precedent and projections for research and education only. It is not financial advice or a prediction of future prices.
