How does the fee reduction feature works? For a non-collateralize exchange, the basic fee is 0.3 but I can apply a fee reduction of 0.3. How would that calculate? Would it end-up been a 0.0 fee or no fee?
Which fee reduction are you referring to?
In the user details, there is a Trading Fee discount Adjust % at the top of the page and when you click on it, you can set a percentage discount.
It wouldnt go below the minimum fees set. The minimum fees supersedes the discount.
