Monitor a TradingView chart in the browser, capture a screenshot via a Chrome extension, route it through n8n to OpenAI, and deliver natural-language insights back to you.
Capture a TradingView chart screenshot from the Chrome extension and prepare it for analysis. The backend routes the image to OpenAI via an n8n webhook to perform image analysis with GPT-4O-MINI's Analyze Image capability. Return a clear, natural-language interpretation of the chart, ready for decision making.
Analyzes a captured chart image to generate concise, actionable insights.
Capture screenshot of TradingView chart via Chrome extension.
Send image to N8N webhook for processing.
Run OpenAI GPT-4O-MINI Analyze Image on the screenshot.
Extract the generated text and insights.
Return insights back to the Chrome extension.
Log the results and errors for traceability.
Before this agent, chart analysis is manual and fragmented across tools. After adopting this agent, analyses are automated, consistent, and easy to share.
A simple three-step flow that non-technical users can operate.
Capture the TradingView chart via the Chrome extension and prepare the image payload.
Send the image to the N8N webhook, which starts the OpenAI Analyze Image node.
Parse the OpenAI response and present the text back to the Chrome extension.
One realistic scenario.
A crypto trader opens tradingview.com, selects the BTCUSDT chart, clicks the Chrome extension to capture the screen, the flow submits the image to the N8N flow, OpenAI analyzes the chart screenshot, and the agent returns a concise interpretation of trends, key levels, and signals.

Practical scenarios to apply AI-assisted chart analysis.
Common questions and practical details.
The flow sends the chart image and the resulting text derived from OpenAI analysis. No raw browser content is uploaded beyond the captured area. You can configure which parts of the UI are included in the screenshot. All data remains under your control within the design of the N8N workflow. If you enable additional fields, ensure they comply with your data policies.
Processing is fast but not truly real-time. It depends on your network, OpenAI response time, and N8N execution. In typical setups, you receive results within a minute or less. You can adjust image size and prompts to optimize latency. This flow is designed for on-demand use rather than streaming feeds.
Yes. The OpenAI node prompts and the interpretation logic can be modified to fit your chart types and preferred terminology. You can tailor instructions for the level of detail, tone, and focus areas (e.g., support/resistance, patterns). Be sure to test changes with representative screenshots. Changes apply to future analyses without affecting previous runs.
The architecture supports adapting the Chrome extension and N8N workflow to other websites. You would adjust the page selectors for screenshot capture and potentially prompt content for the new context. The OpenAI analysis remains the same, but input formatting may vary. A small amount of configuration unlocks multi-site chart analysis.
You need an OpenAI API key, the Cursor AI Chrome extension, and the N8N workflow JSON. The flow must be hosted where you run N8N and accessible by your browser. The TradingView charts you analyze remain on your side; ensure you have permission to capture and analyze them. No third-party services beyond the configured OpenAI access are required.
Data handling follows the security of your OpenAI usage and N8N deployment. Ensure encrypted connections between the Chrome extension, N8N, and OpenAI, and enforce access controls in N8N. Log management should be aligned with your data retention policies. If needed, you can host components within a private network or use on-premises solutions.
Yes. The architecture supports adding more OpenAI nodes or other AI services to expand capabilities (e.g., OCR, sentiment, or pattern detection). You can chain additional steps after Analyze Image to enrich the output. This requires careful prompt engineering and testing on representative screenshots. Ensure compatibility with the current data flow and security guidelines.
Monitor a TradingView chart in the browser, capture a screenshot via a Chrome extension, route it through n8n to OpenAI, and deliver natural-language insights back to you.
