Market Data
AEX provides real-time market data streamed via WebSocket to all connected clients.
Price Grid
The Price Grid is the primary market data view, showing live prices across all products and contracts in a single table.
Each cell displays:
- Bid price and bid quantity — the best buy order
- Ask price and ask quantity — the best sell order
- Last traded price and time — most recent fill
Customising the Price Grid
- Column visibility — show or hide columns via the column configuration menu
- Contract filtering — filter to specific expiry months or quarters
- Favourites — mark contracts you trade frequently for quick access
Time & Sales
The Time & Sales pane shows a chronological feed of all executed trades for a selected contract:
| Time | Price | Quantity | Side |
|---|---|---|---|
| 14:32:05 | 85.50 | 10 | Buy |
| 14:31:58 | 85.25 | 5 | Sell |
Event Log
The Event Log displays real-time platform events:
- Order submissions, cancellations, and rejections
- Trade executions (fills)
- Market session state changes
- System announcements
Use the Event Log to monitor platform activity and troubleshoot order issues.

The status bar at the bottom of the screen shows your WebSocket connection state:
| Indicator | Meaning |

| Reconnecting | Connection lost, attempting to reconnect |
| Disconnected | No connection — data may be stale |
If you see Disconnected for more than a few seconds, check your network connection and refresh the page.
