Terms of Service
Last updated: February 2026
1. Service Description
Chart Library ("the Service") is a web-based tool that provides historical chart pattern matching and analysis for informational and educational purposes only. The Service searches a database of historical stock price data to find patterns that visually resemble a user-provided chart or query, and displays historical forward returns for those matching patterns.
2. Not Financial Advice
Chart Library is not a registered investment advisor, broker-dealer, or financial planner. Nothing on this Service constitutes personalized investment advice, a recommendation to buy or sell any security, or a solicitation to invest. All content, including AI-generated summaries, forward return statistics, and trade simulations, is provided for educational and informational purposes only. You should consult a licensed financial advisor before making any investment decisions.
3. Assumption of Risk
Trading and investing in securities involves substantial risk of loss, including the potential loss of your entire investment. You assume full responsibility for any trading or investment decisions you make. The historical data and pattern analysis provided by Chart Library does not guarantee or predict future results. Past performance is not indicative of future results.
4. Data Accuracy
Market data is sourced from third-party providers including Polygon.io. While we strive for accuracy, we do not guarantee the completeness, timeliness, or accuracy of any data displayed on the Service. Data may contain errors, omissions, or delays. You should verify any information before relying on it for trading decisions.
5. Limitation of Liability
To the fullest extent permitted by applicable law, Chart Library and its operators shall not be liable for any direct, indirect, incidental, consequential, or punitive damages arising from your use of, or inability to use, the Service. This includes, without limitation, any losses resulting from trading decisions made based on information provided by the Service.
6. AI-Generated Content
The Service uses artificial intelligence to generate pattern summaries and analysis. AI-generated content may contain errors or inaccuracies and should not be relied upon as the sole basis for any decision. These summaries are automated interpretations of historical data and do not constitute professional analysis.
7. Eligibility
You must be at least 18 years of age to use the Service. By using Chart Library, you represent that you meet this age requirement.
8. Changes to Terms
We reserve the right to modify these Terms at any time. Continued use of the Service after changes are posted constitutes acceptance of the revised Terms.
