How licensing works

This guide explains activations and sessions in simple terms.

Key concepts

  • License key: the key emailed to you after purchase/download.
  • Activation slot: one allowed active session.
  • accountNumber: your broker account number.
  • chartId: a unique id per chart (or installation/session id depending on EA).

What counts as an activation?

Typically: one running EA instance bound to an accountNumber + chartId.

Deactivation

Deactivate before moving to a new VPS or reinstalling to free a slot.

Common issues

  • Wrong accountNumber
  • Exceeded slots
  • Clock/VPS reset changed identifiers
