How to Add Market Data Handler to Your n8n Workflow

🎯 Goal

Add logic to detect market data alerts and forward them to your bot, while keeping trading signals working normally.

---

📥 Method 1: Import the Pre-Built Nodes (Easier)

Step 1: Download the File

The file is saved at: /home/icke/traderv4/workflows/trading/market_data_handler.json

Step 2: Import into n8n

1. Open your Money Machine workflow in n8n
2. Click the "⋮" (three dots) menu at the top
3. Select "Import from File"
4. Upload market_data_handler.json
5. This will add the nodes to your canvas

Step 3: Connect to Your Existing Flow

The imported nodes include:

• Webhook (same as your existing one)
• Is Market Data? (new IF node to check if it's market data)
• Forward to Bot (HTTP Request to your bot)
• Respond Success (sends 200 OK back)
• Parse Trading Signal (your existing logic for trading signals)

You'll need to:

1. Delete the duplicate Webhook node (keep your existing one)
2. Connect your existing Webhook → Is Market Data? node
3. The rest should flow automatically

🔧 Method 2: Add Manually (Step-by-Step)

If import doesn't work, add these nodes manually:

Step 1: Add "IF" Node After Webhook

1. Click on the canvas in your Money Machine workflow
2. Add node → Search for "IF"
3. Place it right after your "Webhook" node
4. Connect: Webhook → IF node

Step 2: Configure the IF Node

Name: Is Market Data?

Condition:

• Value 1: ={{ $json.body.action }}
• Operation: equals
• Value 2: market_data

This checks if the incoming alert has "action": "market_data" in the JSON.

Step 3: Add HTTP Request Node (True Branch)

When condition is TRUE (it IS market data):

1. Add node → "HTTP Request"
2. Connect from the TRUE output of the IF node
3. Configure:
   • Name: Forward to Bot
   • Method: POST
   • URL: http://trading-bot-v4:3000/api/trading/market-data
   • Send Body: Yes ✅
   • Body Content Type: JSON
   • JSON Body: ={{ $json.body }}

Step 4: Add Respond to Webhook (After HTTP Request)

1. Add node → "Respond to Webhook"
2. Connect from HTTP Request node
3. Configure:
   • Response Code: 200
   • Response Body: {"success": true, "cached": true}

Step 5: Connect False Branch to Your Existing Flow

From the FALSE output of the IF node (NOT market data):

1. Connect to your existing "Parse Signal Enhanced" node
2. This is where your normal trading signals flow

Respond Success    (your existing trading flow...)

✅ Testing

Step 1: Update TradingView Alert

Change your market data alert webhook URL to:

https://flow.egonetix.de/webhook/tradingview-bot-v4

(This is your MAIN webhook that's already working)

Step 2: Wait 5 Minutes

Wait for the next bar close (5 minutes max).

Step 3: Check n8n Executions

1. Click "Executions" tab in n8n
2. You should see executions showing:
   • Webhook triggered
   • IS Market Data? = TRUE
   • Forward to Bot = Success

Step 4: Verify Bot Cache

curl http://localhost:3001/api/trading/market-data

Should show:

{
  "success": true,
  "availableSymbols": ["SOL-PERP"],
  "count": 1,
  "cache": {
    "SOL-PERP": {
      "atr": 0.26,
      "adx": 15.4,
      "rsi": 47.3,
      ...
      "ageSeconds": 23
    }
  }
}

🐛 Troubleshooting

Problem: IF node always goes to FALSE

Check the condition syntax:

• Make sure it's ={{ $json.body.action }} (with double equals and curly braces)
• NOT { $json.body.action } (single braces won't work)

Problem: HTTP Request fails

• Check URL is http://trading-bot-v4:3000/api/trading/market-data
• NOT http://10.0.0.48:3001/... (use Docker internal network)
• Make sure body is ={{ $json.body }} to forward the entire JSON

Problem: Still getting empty cache

• Check n8n Executions tab to see if workflow is running
• Look for errors in the execution log
• Verify your TradingView alert is using the correct webhook URL

🎯 Summary

What this does:

1. ✅ All TradingView alerts go to same webhook
2. ✅ Market data alerts (with "action": "market_data") → Forward to bot cache
3. ✅ Trading signals (without "action": "market_data") → Normal trading flow
4. ✅ No need for separate webhooks
5. ✅ Uses your existing working webhook infrastructure

After setup:

• Trading signals continue to work normally
• Market data flows to bot cache every 5 minutes
• Manual Telegram trades get fresh data
