# Load env and start
source .env && n8n start
# Or with dotenv:
n8n start --tunnel  # optional: for webhook access

Open: http://localhost:5678

1. Open n8n → Settings → Import Workflow (or use the menu icon)
2. Upload workflows/crypto_trading_bot.json
3. The workflow will be imported in inactive state

Go to Credentials and create:

After creating credentials:

• Open the DB: Log Signal node → select your Postgres credential
• Open the Telegram: Send Alert node → select your Telegram credential
• All other nodes use env vars directly (no n8n credentials needed)

Before enabling, run manually:

1. Open the workflow canvas
2. Click Execute Workflow (play button, top right)
3. Watch the execution step by step
4. Check Postgres: SELECT * FROM signals ORDER BY created_at DESC LIMIT 5;
5. Check Telegram for your notification

Once tested, toggle Active in the top-right of the workflow canvas. The bot will run every 5 minutes automatically.

• LIVE_TRADING_ENABLED=false → all orders are simulated and logged, no real API calls to place orders
• Bybit base URL https://api-demo.bybit.com → demo account only
• Hard guards: confidence threshold, Kelly half-fraction, max leverage cap
• Risk AI double-checks every signal before approval
