About this app

Chart Echo: the market remembers.

Every chart you're looking at has happened before. Chart Echo helps you
find those moments: frame a pattern on stocks or crypto charts, and it
searches a vast archive of historical price action for the closest
matches, the "echoes", then shows you what happened next.

What used to be a dense research workflow becomes a simple, swipeable journey:

• Market: search a stock or crypto, or start from a popular pick.
• Frame: set the window of candles you want to match.
• Matches: browse the historical patterns that most resemble yours, ranked by similarity.
• Echo: overlay a match on your chart and read the outcome stats: how often it continued up or down, the typical move size, and the market context (trend and volatility) around it.
• Act: save the workspace, share gifs and images, and set alerts to see how the fractal plays out, or get notified when your chart prints a strong pattern projection.

WHAT MAKES IT DIFFERENT
Most charting apps draw indicators on top of the present. Chart Echo looks backward to put the present in context by using the same underlying pattern matching tools that hedge funds or expensive custom trading applications use - matching the actual shape of price, not just a single number, against decades of history. The result is a clear read on how comparable setups have resolved before, with provided context on market conditions at the time.

FEATURES
• Pattern matching across stocks and crypto
• Similarity-ranked historical "echoes"
• Outcome statistics - direction, magnitude, and frequency
• Trend and volatility context for every match
• Save workspaces and see how the pattern played out
• Alerts when your chart matches a historical setup, bullish or bearish
• Export your findings as images/gifs to share

FREE & PREMIUM
The core workspace is free and works without an account - frame a pattern and explore its echoes right away. Premium unlocks more: additional timeframes, saved workspaces, unlimited alerts, and image export. Manage your subscription anytime.

A NOTE ON RESPONSIBLE USE
Chart Echo is a research and educational tool. Historical pattern similarity is not a prediction, and past performance does not guarantee future results. Nothing in the app is financial, investment, or trading
advice. Always do your own research and consider your risk before making any decision.
