# 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

   ↓                    ↓
  TRUE               FALSE
   ↓                    ↓
Forward to Bot     Parse Signal Enhanced
   ↓                    ↓
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

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

Should show:
```json
{
  "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

**Import the JSON file or add the nodes manually, then test!** 🚀
