AI-Powered SENSEX Signal Generator
AI-Powered SENSEX Signal Generator > Gemini, Yahoo Finance & Google Sheets This n8n workflow automatically analyzes SENSEX market data using technical indicators and AI (Google Gemini) to generate trading signals (Buy/Sell). It filters only high-confidence signals and logs them into Google Sheets for tracking. Quick Implementation Steps Import the workflow into your n8n account Add credentials: Google Gemini API Google Sheets OAuth2 Create a Google Sheet with columns: Date | Index | Signal | Confidence | Trend | Reason Execute the workflow manually Check results in your Google Sheet What It Does This workflow automates stock market signal generation for the SENSEX index using a hybrid approach that combines technical analysis and AI-based reasoning. First, it fetches historical market data from Yahoo Finance and computes key indicators such as moving averages, momentum, volatility and price change. These indicators help identify the current market trend and behavior. Next, it retrieves the latest SENSEX-related news headlines and feeds both the technical data and news into a Google Gemini AI model. The AI analyzes this combined input to generate a trading signal (Buy/Sell), along with confidence, strength, risk level and reasoning. Finally, the workflow calculates a score based on AI output, filters only high-quality signals (score > 70) and logs them into Google Sheets for further tracking and decision-making.
