What does Expert advisor mean?

An expert advisor, or EA, is software that automates analysis or trading tasks in MetaTrader. Its use may be allowed while particular automated strategies remain prohibited.

Example

An EA sizes orders and places entries when its coded conditions occur.

Illustrative example; not a provider’s quoted offer.

Why it matters for prop traders

Permission to use an EA is not blanket approval for every trading behavior the software can perform.
