AI Stock Analyst Bot (TwelveData & Chart-IMG)

Role & Agent Persona

Monitors custom stock tickers triggered from Telegram, fetches live market metrics via TwelveData, extracts sentiment from NewsAPI, structures analytical reports via GPT-4, and visualizes trends using Chart-IMG API.

The Operational Bottleneck (Before vs. After)

🛑 Manual Bottleneck

Analyzing financial assets requires switching between terminal feeds, news aggregators, and technical chart generators. Manual research takes 1-2 hours per stock ticker, slowing down critical trading decisions.

⚡ Autonomous Solution

100% automated asset vetting. Fetches real-time price updates, processes sentiment from global news, renders a technical chart, and dispatches a comprehensive investment report to Telegram in 30 seconds.

The Core Problem Detail:

Our client, a private trading fund, spent hours vetting potential equity entries daily. Analysts had to manually retrieve technical indicators (RSI, MACD) from TwelveData, scrape recent financial news using NewsAPI, draft a structured fundamental summary, and take screenshots of trading charts to compile stock reports for the investment committee.

This research process took 90 minutes per stock, leaving the team exposed to market latency and delayed entries on volatile assets. Subscriptions to high-end financial terminals cost the fund over $1,500/month.

Other Potential Industry Applications:
  • Wealth Management: Automates daily portfolio performance updates and market news summaries sent to high-net-worth clients.
  • Crypto Trading Bots: Monitors blockchain wallet movements and pulls live technical crypto indicators to signal buy/sell opportunities.
  • Fintech Apps: Powers customer-facing chatbot assistants that answer questions about stock price histories and analyst recommendations.

The Engineered Automation Fix:

We built an automated Telegram financial analysis pipeline in n8n. When a user types a stock symbol (e.g., /analyze AAPL) in Telegram, n8n captures the command via Webhook. The workflow simultaneously queries TwelveData API for the stock's indicators/price updates and NewsAPI for recent articles. It formats the data, prompts GPT-4 to act as a senior quant analyst to rate the stock's outlook, and uses Chart-IMG API to render a clean visual stock price chart. Finally, the n8n pipeline sends the formatted PDF report and the generated chart image directly back to the Telegram chat.

Technical Implementation & Node Architecture

Telegram webhook triggers an n8n workflow that branches into parallel HTTP requests (TwelveData & NewsAPI). Data is compiled and parsed in a Code node, analyzed via GPT-4, and visual charts are requested from Chart-IMG API before a final multipart Telegram message is dispatched.
