This is a Prometheus-compatible exporter that scrapes and exposes live MT4 trading metrics, such as exchange rates, trade positions, account stats, and more — all in /metrics format.

Originally developed by MoNoRi-Chan, the feline anarcho-capitalist coder of the late-stage financial underworld.

• Real-time bid/ask rates per symbol
• Active trade tickets with labels (ticket, symbol, type, lots)
• Live account balance, equity, free margin
• Number of open trades
• Exported in Prometheus /metrics format

Example /metrics output:

# HELP mt4_rate_bid Bid price per symbol
# TYPE mt4_rate_bid gauge
mt4_rate_bid{symbol=\"XAUUSDc\"} 3386.32

# HELP mt4_trade_info Trade info by label
# TYPE mt4_trade_info gauge
mt4_trade_info{ticket=\"460842232\",symbol=\"AUDUSDc\",type=\"BUY\",lots=\"0.05\"} 1

• Redis backend (used as temporary storage by the data push agent)
• Node.js 18+ environment
• MT4 plugin / bridge that pushes real-time trade data to Redis
• Prometheus 2.x

• Must run on port 80 (required by some brokers/MT4 bridge tools due to hardcoded endpoints)
• Metrics are exposed over HTTP or HTTPS – if you're running behind reverse proxies like NGINX or Cloudflare, ensure /metrics is not being cached or blocked
• Uses Redis keys() command which may be slow with large datasets
• Duplicate metric registration crash if .set() is called repeatedly without caching the metric instance
• Doesn't currently support MT5 (because MetaQuotes said 🖕 to open systems)

Below is an example of prometheus.yml configuration for this exporter:

scrape_configs:
  - job_name: 'mt4-exporter'
    # scheme: https
    metrics_path: /metrics
    static_configs:
      - targets: ['localhost']  # or your own exporter domain/IP
    scrape_interval: 10s
    # tls_config:
    #   insecure_skip_verify: true  # use only if using self-signed certs

⚠️ Note: Do not include https:// in the targets field — just the domain or IP. Prometheus will handle HTTPS via the scheme field.

After deploying, verify exporter availability:

curl -k http://localhost/metrics

Or open it in your browser.

You can easily build dashboards using the following metric types:

• mt4_rate_bid{symbol}
• mt4_rate_ask{symbol}
• mt4_trade_info{ticket, symbol, type, lots}
• mt4_balance
• mt4_equity
• mt4_margin_free
• mt4_open_trades
