EA API Keys

A key is how your Expert Advisor proves it is yours. It replaces a password, so treat it like one.

Creating a Key

  1. 1Open Settings, then Accounts, and click EA API Key.
  2. 2Create a key. It appears in full, once you ask to see it.
  3. 3Copy it and paste it into the EA’s LedgerrApiKey input in MetaTrader.

Keys do not expire. The list shows each key and lets you copy, rotate or delete it, so you can keep one key per machine and recognise them later.

Rotating and Revoking

RotateIssues a new value for that key. The old value stops working immediately — update the EA before your next session.
DeleteRemoves the key for good. Any terminal still using it stops syncing at once.
Trades already syncedUnaffected by either. Your history stays whatever happens to the key.

A key is a credential

Anyone holding it can write trades into your journal. Do not post it in a screenshot, a support message or a public chat. If it leaks, rotate it — it takes one click and costs you nothing.

Good Practice

  • One key per machine, named so you know which is which.
  • Rotate after selling or reinstalling a VPS.
  • Delete keys for terminals you no longer run, rather than leaving them live.
  • Never reuse the key anywhere other than the Ledgerr EA.
