Trading fees are based on your Tier level and relevant maker and taker fees. 

To view your current Tier level, go to Settings > Profile. 

• Tier levels vary depending on the volume you have traded over the past 30 days.
• Staking $TOMB in your Felix exchange wallet would also unlock higher Tier levels, enabling discounted trading fees of up to 0.02% Maker Fees and 0.04% Taker Fees on your account. Please see here for further details on $TOMB staking. 

Everyday at 00:00 AM (UTC), your trading volume over the past 30-day period will be evaluated. Your Tier level and corresponding maker/taker fees are updated at 01:00AM (UTC).

• When you place an order that is immediately filled in its entirety (for example a market or stop order) you are a “taker,” and you pay a “taker” fee for this. The idea is that you are “taking” the price you want, right now, by buying or selling limit orders sitting on the books.

Limit Immediate or Cancel (IOC) and Limit Fill or Kill (FOK) orders (accessible via the API) are also considered taker orders.

• Meanwhile, when you place an order that doesn’t fill immediately (like a limit order), you are a “maker,” and you can expect to pay a reduced “maker” fee for this. As noted above, this terminology comes from the fact that placing limit orders on the books helps to “make the market,” (it makes you a “market maker”).
