Overview
Scan live charts with Weinstein Stage Analysis or your own rules.
OttaCharts runs your trading rules on any chart and returns a structured read — trend stage, setup type, MA alignment, relative strength, volume pattern, risk map, and an actionability verdict. Works on TradingView, Yahoo Finance, Finviz, Schwab, and more. HOW IT WORKS Open a chart, click the Otta Charts button, and scan. The extension captures the visible chart and runs it through your active ruleset using AI analysis. Results appear in a side panel without leaving the page. FREE (bring your own API key) • Weinstein Stage Analysis ruleset built in • One custom ruleset • Manual scans on any supported chart site • Local export / share card PRO ($29/month or $290/year) • 100 hosted scans/month — no API key needed • BYOK auto-scan — set an interval, Otta Charts scans automatically • Chart chat — ask follow-up questions about any scan • Multiple rulesets synced across devices • Watchlists and alerts YOUR DATA In Free mode, your chart goes directly from the extension to your AI provider. It never touches Otta Charts' servers. In Pro hosted scan mode, the chart image is processed transiently and discarded immediately — never stored. All output is educational analysis only — not financial advice.
