What a rebate service pays instead
A rebate service is an affiliate funded separately, on top of the exchange's automatic discount.

What to check before you trust a rebate service
- Exchange-reported commission, or a made-up number?
- Can you see your accrued amount?
- What happens on a reversed or cancelled trade?
