Dhan-MT5 Bridge v2.1 - DIRECT MONITORING EDITION

The middleware monitors your MT5 terminal directly - No separate EA needed!

Automatically mirrors ALL your MT5 positions to Dhan MCX in real-time. Trade normally in MT5 (manual or with any EA), positions automatically execute on Dhan.

---

How It Works

The Bridge Monitors MT5 Directly

┌─────────────────┐
│  MT5 Terminal   │
│  (Your trades)  │
└────────┬────────┘
         │
         │ MetaTrader5 Python API
         │ (Direct connection)
         ▼
┌─────────────────┐
│  Dhan Bridge    │ ◄─── Monitors every 2 seconds
│  (Middleware)   │ ◄─── Detects ALL changes
└────────┬────────┘
         │
         │ Dhan API
         ▼
┌─────────────────┐
│   Dhan MCX      │
│  (Auto-synced)  │
└─────────────────┘

What This Means:

• Trade manually in MT5 → Auto-syncs to Dhan
• Use ANY EA in MT5 → Auto-syncs to Dhan
• Close positions → Auto-closes on Dhan
• NO separate EA to install
• NO code changes to your EA
• Works with everything

5-Minute Setup

Step 1: Install

git clone <your-repo>
cd dhan-mt5-bridge
chmod +x scripts/setup.sh
./scripts/setup.sh

Step 2: Add Credentials

nano .env

Add:

DHAN_CLIENT_ID=your_client_id
DHAN_ACCESS_TOKEN=your_access_token

Step 3: Make Sure MT5 is Running

IMPORTANT: The bridge connects directly to MT5, so:

• MT5 terminal must be running
• Must be logged into your MT5 account
• Bridge runs on same machine as MT5

Step 4: Start Bridge

python -m app.main

Expected output:

Starting Dhan-MT5 Bridge with DIRECT MT5 MONITORING...
INFO - MT5 connected, account=12345, server=YourBroker-Demo
INFO - Syncing 0 existing positions
INFO - MT5 Direct Monitoring started - ALL positions auto-synced
============================================================
Dhan-MT5 Bridge READY
============================================================
MT5 Monitoring: ACTIVE
Auto Sync: ENABLED
Manual Trading: SUPPORTED
Any EA Trading: SUPPORTED
============================================================

Step 5: Start Trading!

That's it! No EA to install. Just trade.

1. Open MT5
2. Buy/Sell manually OR run your EA
3. Watch the bridge logs
4. Positions auto-sync to Dhan

Example Usage

Manual Trading

1. You click BUY 0.1 XAUUSD in MT5

2. Bridge detects it (within 2 seconds)
   ↓
3. Bridge creates order on Dhan:
   - Symbol: GOLDMFEB2025FUT
   - Lots: 1
   - Side: BUY
   ↓
4. Position synced!

5. You click CLOSE in MT5
   ↓
6. Bridge detects close
   ↓
7. Bridge closes Dhan position
   ↓
8. Both closed!

With Your EA

1. Your EA opens position (any EA)
   ↓

   ↓
3. Syncs to Dhan
   ↓
4. Done!

(Your EA doesn't need ANY changes)

Monitoring

Check MT5 Connection

curl http://127.0.0.1:8000/mt5/status | jq

Response:

{
  "success": true,
  "monitoring": {
    "mt5_connected": true,
    "tracking_positions": 2,
    "poll_interval": 2,
    "running": true,
    "tracked_tickets": [12345, 12346]
  },
  "message": "MT5 terminal being monitored directly"
}

Check Health

curl http://127.0.0.1:8000/health | jq

View Logs

tail -f logs/bridge.log

You'll see:

INFO - MT5 position opened detected, ticket=12345, symbol=XAUUSD, type=BUY
INFO - Position synced to Dhan, dhan_order_id=112233, mcx_contract=GOLDMFEB2025FUT
INFO - MT5 position closed detected, ticket=12345
INFO - Dhan position closed, dhan_order_id=112234

---

Configuration

Change Polling Interval

In app/main.py, change:

mt5_config = {
    "poll_interval_seconds": 2,  # Check every 2 seconds
}

Faster (1 second):

• More responsive
• Higher CPU usage

Slower (5 seconds):

• Less CPU usage
• Slower detection

Recommended: 2 seconds (good balance)

---

Troubleshooting

"MT5 not connected"

Check:

1. Is MT5 terminal running?
2. Are you logged into MT5?
3. Is bridge on same machine as MT5?

Fix:

# Make sure MT5 is running
# Then restart bridge
python -m app.main

"No positions detected"

Check:

• Bridge logs: tail -f logs/bridge.log
• MT5 status: curl http://127.0.0.1:8000/mt5/status

Positions Not Syncing

Possible causes:

1. Dhan credentials wrong → Check .env
2. Market closed → Check /status/session
3. Symbol not mapped → Check config/symbols.yaml

Solution:

# Check logs
tail -100 logs/bridge.log | grep -i error

# Check Dhan connection
curl http://127.0.0.1:8000/health | jq '.dhan_connected'

Technical Details

How MT5 Monitoring Works

The bridge uses MetaTrader5 Python package:

import MetaTrader5 as mt5

# Connect to MT5
mt5.initialize()

# Get all positions
positions = mt5.positions_get()

# Monitor for changes
while True:
    current_positions = mt5.positions_get()
    # Detect new/closed positions
    # Sync to Dhan
    sleep(2)

Requirements

• Python 3.10+
• MT5 terminal (Windows or Wine on Linux)
• Dhan account with API access
• Same machine for bridge and MT5

Architecture

MT5 Terminal
    ↓ (MetaTrader5 package)
MT5 Monitor (app/core/mt5_monitor.py)
    ↓
Position Manager (SQLite)
    ↓
Dhan Client (API wrapper)
    ↓
Dhan MCX

---

API Endpoints

MT5 Monitoring

# Get monitoring status
GET /mt5/status

# Health check
GET /health

# Positions
GET /positions

# Queue status
GET /status/queue

# Rollover status
GET /rollover/status

Manual Order (Optional)

# You can also place orders via API
POST /order/new
{
  "symbol": "XAUUSD",
  "side": "BUY",
  "order_type": "MARKET",
  "volume": 0.1
}

But with monitoring, just trade in MT5!

Important Notes

ONE CRITICAL TASK

Implement Dhan Security ID lookup:

# In app/core/mt5_monitor.py
async def _get_security_id(self, mcx_info: Dict) -> Optional[str]:
    # TODO: Query Dhan security master
    securities = await self.dhan.get_security_list(exchange="MCX")
    for sec in securities:
        if sec['tradingSymbol'] == mcx_info['contract']:
            return sec['securityId']
    return None

This is the ONLY manual task needed.

Best Practices

1. Start with paper trading (3+ days)
2. Monitor logs closely first week
3. Start with 1 commodity
4. Small position sizes initially
5. Gradually scale up

Limitations

• Bridge and MT5 must be on same machine
• Requires MT5 terminal to be running
• 2-second detection delay (adjustable)
• SL/TP changes logged but not auto-synced to Dhan
