License & Server Connection — Nexus Copier Manual

License Key

Your unique Nexus Copier license key, tied to your MT5 account number. Must be entered here and in the Configurator's License tab. The EA validates this key against the license server on startup and periodically during operation.

Server URL

Default: http://127.0.0.1:5000/get_trade

The full URL of the NexusServer polling endpoint. Only change this if you modified the default port (5000) in the server configuration, or if running the server on a different machine on your local network.

⚠️ Note: If running on a VPS where NexusServer and MT5 are on the same machine, keep the default 127.0.0.1. Do not expose this port to the internet.

Account ID

Default: "default"

Unique identifier for this MT5 account instance. When running multiple MT5 accounts, each must have a unique Account ID so the server can route signals to the correct account.

💡 Multi-account example: Account 1: ID = "account_main" | Account 2: ID = "account_prop" | Account 3: ID = "account_test"

Update Interval (seconds)

Default: 1

How often (in seconds) the EA polls the NexusServer for new signals. 1 second is recommended for near-real-time signal reception. Increase to 2–3 if your VPS has limited resources.

Connection Alert Cooldown (minutes)

Default: 300 minutes

Minimum time between connection error alert notifications. Prevents the EA from flooding you with alerts if the server is temporarily unreachable.

Max Retries / Retry Delay (ms)

Default: 3 retries / 1000ms

On a failed connection attempt, the EA retries up to Max Retries times, waiting Retry Delay milliseconds between each attempt before reporting a connection error.

Enable Auto-Update / Update Check Interval

Default: true / 24 hours

The EA periodically checks for new versions. When an update is available, a notification appears in the EA's chart comment. Disable this if you prefer manual update control.
