Chart Echo

Chart Echo turns chart-reading into a guided hunt. Frame a pattern on any stock or crypto chart, and Chart Echo searches decades of market history for the setups that looked just like it — then shows you, statistically, what happened next. A deck of cards walks you through it: • Market — pick a stock or crypto, or start from a popular ticker. • Frame — set the window of candles that defines your pattern. • Matches — browse the closest historical echoes, ranked by similarity. • The Echo — overlay a match and read the outcome: bullish/bearish bias, confidence, trend and volatility context.• Act — save the workspace, set an alert, or share a Story. Premium unlocks intraday timeframes, unlimited searches, saved workspaces synced across devices, watermark-free Story exports, and unlimited pattern alerts. Chart Echo is a research and education tool. It is not financial advice, and no pattern match, score, or projection is a recommendation to buy or sell. Markets are risky and you can lose money — always do your own research. Terms of Use (EULA): https://chart-echo.com/terms
