// See it in action
The only card app that reads the chart.
Collection trackers tell you what you own. CardChart tells you when to move.
// 01 · Buy & Sell Signals ★ nobody else has this
Signals that tell you when — and why
An engine backtested on real card histories flags BUY, SELL and take-profit moments right on the chart — each with the reason in plain English. Capitulation, blow-off tops, exhaustion.

- Fibonacci retracement & extension
