    What This Automation Does

    This workflow solves the problem of slow and manual stock research by automating analysis and chart creation using a Telegram bot. It handles voice and text queries, makes a stock chart, analyzes it with AI, and sends results back fast. Traders get quick, easy-to-understand insights without spending hours searching or calculating.   The workflow accepts Telegram messages. If voice, it transcribes to text using OpenAI. Then, it calls a chart API to generate detailed stock charts. AI models analyze charts for technical signals like RSI and candlestick patterns. Results come back as images and text replies on Telegram. Stocks can be saved in Airtable for scheduled batch reports.  

    What the Bot Actually Tells You — Buy & Sell Signals

    Most traders don't just want a chart. They want to know one thing:
    should I buy, sell, or hold right now?

    This is exactly what the AI delivers after analyzing your stock.

    After you send a ticker like AAPL or TSLA, here's what comes back
    in your Telegram:

    BUY SIGNAL indicators the AI looks for:

    → RSI below 30 — stock is oversold, potential bounce incoming
    → Bullish candlestick patterns — hammer, morning star, engulfing
    → Price holding above key support levels
    → Volume spike confirming upward momentum

    SELL SIGNAL indicators the AI looks for:

    → RSI above 70 — stock is overbought, potential pullback
    → Bearish candlestick patterns — shooting star, evening star, doji
    → Price breaking below key support
    → Declining volume on upward moves — weak rally warning

    ⚠️ HOLD indicators:

    → RSI between 40–60 — neutral zone, no strong signal
    → Consolidation pattern — stock moving sideways
    → Mixed signals across indicators — AI flags uncertainty

    Every analysis reply includes a plain-English summary so you know
    exactly what the signals mean — no chart-reading experience needed.

    Your Personal Stock Analysis Bot — Inside Telegram

    Think of this as having a stock analysis bot available 24/7
    directly inside your Telegram app.

    No extra apps. No new dashboards. No subscriptions.

    Just message your bot a ticker symbol — by text or even by voice —
    and your personal stock bot responds with:

    → A full technical chart with RSI, candlestick overlays, and
    volume indicators
    → An AI-written analysis of what the chart signals
    → A clear buy, sell, or hold summary in plain English
    → Automatic scheduled reports for your saved watchlist

    It works like texting a friend who happens to be a professional
    stock analyst — except it never sleeps, never charges per question,
    and responds in seconds.

    This is for active stock traders and analysts who spend much time manually searching and analyzing charts. It helps those who want faster, automated stock insights via Telegram. Also good for friends or groups needing quick, expert-level stock answers.

    Frequently Asked Questions

    Can other chart APIs replace the current chart image node?

    Yes, any chart API that accepts similar requests and returns image URLs can be used in place of the existing HTTP Request node.

    Does the workflow use much OpenAI API credit?

    OpenAI usage depends on message volume and models used. GPT-4 and audio transcription cost more tokens. Monitor OpenAI usage carefully.

    Is data safe in this automated Telegram stock analysis?

    All API calls use HTTPS securely. Telegram messages are encrypted. Data control remains with the user in Airtable and API keys.

    Can the workflow support more technical indicators for analysis?

    Yes, add desired indicators to the "studies" array in the Chart API request body for deeper technical insights.
