Technical Indicators Used in Strategy

Core Indicators (1-Day Timeframe):

  1. EMA 50 & EMA 200: Trend direction and momentum confirmation
  2. RSI (14-period): Momentum oscillator for overbought/oversold conditions
  3. ATR (14-period): Volatility measurement for risk sizing
  4. Support/Resistance: Dynamic levels calculated from 90-day price history.
  5. Fibonacci Retracements: Additional confluence levels.

Important Disclaimers

  • ⚠️ Analysis timeframe is set to 1-day by default - suitable for swing trading, not day trading
  • ⚠️ Not a get-rich-quick system - This tool provides technical analysis, not financial advice
  • ⚠️ Use with fundamental analysis - Technical signals work best when combined with fundamental research for timing entries and exits
  • ⚠️ Not recommended for isolated use - Always consider fundamentals, market conditions, news, and risk management

Key Features

  • Single, clear signal per analysis (no conflicting recommendations; either buy or sell)
  • Built-in confidence scoring system
  • Automated chart generation and delivery
  • Support for any US stock ticker
  • Professional-grade risk management parameters

Use Case Examples

  1. Pre-market Analysis: Send "AAPL" stock ticker as a message to your telegram bot and get comprehensive technical analysis with 1 Day candlesticks chart
  2. Swing Trading: Use signals to time entries on already-researched stocks
  3. Portfolio Review: Analyze multiple positions for exit timing
  4. Educational Tool: Learn technical analysis through AI explanations

This template transforms complex technical analysis into accessible, actionable trading insights while maintaining professional risk management standards.

n8n Workflow: Generate Stock Trading Signals with Gemini 2.5 Pro & TwelveData via Telegram Bot

This n8n workflow empowers you to get real-time stock trading signals directly through a Telegram bot. By integrating with TwelveData for stock data and leveraging Google Gemini 2.5 Pro for AI analysis, it provides intelligent buy/sell recommendations based on your queries.

What it does

This workflow automates the following steps:

  1. Listens for Telegram Commands: The workflow is triggered when a user sends a message to a configured Telegram bot.
  2. Extracts Stock Symbol: It processes the incoming Telegram message to identify the stock symbol (e.g., "AAPL", "GOOGL") the user is interested in.
  3. Fetches Real-time Stock Data: It makes an API call to TwelveData to retrieve real-time stock data for the extracted symbol.
  4. Prepares Data for AI Analysis: The fetched stock data is formatted and combined with the user's query to create a comprehensive prompt for the AI.
  5. Generates Trading Signals with Google Gemini: The prepared data is sent to Google Gemini 2.5 Pro, which analyzes the stock information and generates a trading signal (e.g., "Buy", "Sell", "Hold") along with a brief explanation.
  6. Formats AI Output: The AI's response is parsed to extract the trading signal and any additional insights.
  7. Sends Signal to Telegram: The generated trading signal and explanation are sent back to the user via the Telegram bot.
  8. Handles Delays: A Wait node is included to manage API rate limits or introduce a pause if necessary.

Auto-reply & create Linear tickets from Gmail with GPT-5, gotoHuman & human review

This workflow automatically classifies every new email from your linked mailbox, drafts a personalized reply, and creates Linear tickets for bugs or feature requests. It uses a human-in-the-loop with gotoHuman and continuously improves itself by learning from approved examples. How it works The workflow triggers on every new email from your linked mailbox. Self-learning Email Classifier: an AI model categorizes the email into defined categories (e.g., Bug Report, Feature Request, Sales Opportunity, etc.). It fetches previously approved classification examples from gotoHuman to refine decisions. Self-learning Email Writer: the AI drafts a reply to the email. It learns over time by using previously approved replies from gotoHuman, with per-classification context to tailor tone and style (e.g., different style for sales vs. bug reports). Human Review in gotoHuman: review the classification and the drafted reply. Drafts can be edited or retried. Approved values are used to train the self-learning agents. Send approved Reply: the approved response is sent as a reply to the email thread. Create ticket: if the classification is Bug or Feature Request, a ticket is created by another AI agent in Linear. Human Review in gotoHuman: How to set up Most importantly, install the gotoHuman node before importing this template! (Just add the node to a blank canvas before importing) Set up credentials for gotoHuman, OpenAI, your email provider (e.g. Gmail), and Linear. In gotoHuman, select and create the pre-built review template "Support email agent" or import the ID: 6fzuCJlFYJtlu9mGYcVT. Select this template in the gotoHuman node. In the "gotoHuman: Fetch approved examples" http nodes you need to add your formId. It is the ID of the review template that you just created/imported in gotoHuman. Requirements gotoHuman (human supervision, memory for self-learning) OpenAI (classification, drafting) Gmail or your preferred email provider (for email trigger+replies) Linear (ticketing) How to customize Expand or refine the categories used by the classifier. Update the prompt to reflect your own taxonomy. Filter fetched training data from gotoHuman by reviewer so the writer adapts to their personalized tone and preferences. Add more context to the AI email writer (calendar events, FAQs, product docs) to improve reply quality.
