What the rebate depends on
The rate is not the same for every broker or account type. Check the broker, account, market and unit together. DualNet’s API data shows the recorded rates for each account type.
A real example
Axi lists 1.92 USD per lot for Forex on its Standard account and 0.64 USD per lot on Pro. These are different account terms, not a statement about profit or total trading costs.
