Build a monitoring dashboard for an EA

A compact dashboard should answer whether the terminal is alive, what risk is open, and why the system is or is not trading.

Show health before performance

The first screen should show last heartbeat, terminal connection, account identity, current symbol, EA version, and protection state. A profit number without health information can look reassuring while the terminal is offline.

Use explicit stale states rather than replacing missing data with zeros.

Show the risk picture

Include balance, equity, open positions, daily loss, overall drawdown, current risk, and remaining room before a personal or hard limit. Make the units and calculation time visible.

Separate realised and floating P&L.
Show symbol and direction for every open position.
Display the last successful broker update.
Highlight halted, disconnected, or stale states.

Design for the incident

A dashboard is most valuable when something is wrong. Add links or identifiers for the relevant log entries, configuration version, and deployment date. Avoid decorative charts that hide the one alert an operator needs.

Test the dashboard with missing, delayed, and malformed data so it fails visibly rather than presenting false confidence.
