Product Overview
DW Connection Monitor MT4 is a lightweight utility EA for MetaTrader 4 that keeps a constant eye on your terminal's connection to the broker and its network latency. The moment your connection drops — or comes back — it sends a push notification straight to your phone, so you always know the real state of your trading terminal, even when you're away from the screen.
It's built for traders running EAs on a VPS or a home PC who need to be sure their automated strategies are actually online and executing.
Key Features
- LOST / RESUME alerts — get a push (and optional pop-up) the moment the broker connection drops or recovers, including the exact downtime duration.
- Jitter-proof — a confirmation delay filters out brief network flickers, so you only get real alerts, never notification spam from momentary blips.
- High-ping warning — set a latency threshold (e.g. 200 ms); if ping stays above it you get a "High Ping" push, and a "Recovered" push once it drops back to normal.
- Clean on-chart panel — live connection status, broker name, account, server, colour-graded ping (green / yellow / red), and the last disconnection with its timestamp and duration. The panel auto-sizes to its content.
- Flexible layout — place the panel in any corner and pick your text size.
- Resource-friendly — timer-based checks with event-driven drawing; no load on every tick, and it keeps working on weekends when there are no ticks.
How to Use
1. Install
- Install from Market
2. Enable phone push notifications (one-time)
- Install the MetaTrader app on your phone and open Settings > Messages to find your MetaQuotes ID.
- On the desktop terminal: Tools > Options > Notifications > tick Enable Push Notifications and paste your MetaQuotes ID > OK.
- Send a test to confirm it works.
3. Attach to a chart
- Drag the EA onto any one chart (one instance monitors the whole terminal — you don't need it on every chart).
- On the Common tab, make sure Allow Algo Trading is enabled.
- Set the inputs (below) and click OK. The panel appears immediately.
4. Inputs
| Input | Purpose |

| Note | A label to identify this terminal in your notifications (e.g. VPS-1 , Home PC ). Optional. |

| Push notification on LOST / RESUME | Send a phone push when the connection drops / recovers. |
| Alert() popup on LOST / RESUME | Also show a desktop pop-up. |
| High-ping threshold (ms) | Ping above this triggers the high-ping alert. Set 0 to turn the ping alert off. |
| Push notification on high ping | Send a push on high ping and on recovery. |
| Seconds ping must stay high | Ping must exceed the threshold this long before the first alert (filters spikes). |
| Panel position | Top-Left / Top-Right / Bottom-Left / Bottom-Right. |
| Panel text size | Extra Small / Extra Large. |
5. Read the panel
- CONNECTED / LOST — live connection status (green / red), with the broker name beside it.
- Ping — current latency, colour-graded: green (good), yellow (elevated), red (above your threshold).
- Last down — date, time and duration of the most recent disconnection.
Notes
- The EA monitors only — it never places, modifies, or closes trades.
- Notifications rely on MetaQuotes push; if a push fails, check the terminal's Notifications settings and your MetaQuotes ID.
- Keep the terminal (or VPS) running for monitoring to stay active.
