We have the same spread as BitBy, our data provider. Since our platform does not support partial fills, if your order can't be filled for the full amount at your limit order price due to the spread, it will not be filled at all. 

To remedy this, we recommend splitting up your limit orders and/or checking the depth of market tool in our CPX platform to see the available liquidity at a given price level.To address this, we suggest that you break up your limit orders and/or use the depth of market tool on our CPX platform to view the liquidity that is available at a particular price
