There are two fee models in Bitso, those that are calculated in markets traded against BTC and those that are calculated in markets traded against Mexican Pesos, MXN. In both cases, the fee you pay decreases as your volume increases within a 30-day range. These are both based on a Maker-Taker scheme. If you want to know the fess you are paying, select the pair you are interested in (BTC/MXN or ETH/BTC) and it will display; your current fee, as well as how much volume you need to reach the next level.
The orders denominated as Taker, are those that take the liquidity of the market to consume a purchase order or sale order previously placed by a Maker.
