Question 1

What is Chart Library?

Accepted Answer

Chart Library is a chart-pattern intelligence engine for humans and AI agents. Anchor any (symbol, date, timeframe) and it returns the cohort of historical analogs — from 25M+ indexed patterns across 19,000+ symbols and 10 years — what those analogs did next, and a calibrated forward-return distribution, over web, REST API, and MCP.

Question 2

Does Chart Library predict stock prices?

Accepted Answer

No. Chart Library never forecasts. It returns historical distributions — what actually happened after setups like yours (median, p10/p90 band, up rate) — plus the receipts to audit them. Direction and decisions stay with you or your agent.

Question 3

How calibrated are Chart Library's bands?

Accepted Answer

Chart Library publishes a dated rolling coverage record, sequential trust audit, and known conditioning failures at chartlibrary.io/calibration. Frozen held-out evaluations are labeled separately from current service status.
