what does goat funded trader add-on mean?

An add-on is an extra feature you can purchase for some extra money. For example goat funded trader profit split is 80% but you can purchase a 100% profit split as an add-on.

An add-on is an extra feature which you have to purchase. Think of it like an in-app purchase you make for games.

It's like an in-app purchase in a computer game. After paying for your evaluation/challenge, you can still purchase additional custom features called add-ons

An add-on is an optional extra feature you can purchase when buying a challenge to customize your account.

Think of it like buying a phone and choosing extra options such as:

extra storage,

insurance,

faster charger.

The phone still works without them — but add-ons give extra benefits.

It’s the same idea in prop firms.
