PDAX charges 0.5% trading fee for market orders (taker) and 0.4% trading fee for limit orders (maker).
If you’ve placed a buy limit order that’s above the market price or a sell limit order that’s below the market price, your limit order will automatically be converted into a market order.
When this happens, you will be charged the 0.5% trading fee for market orders accordingly. You will also see a message informing you that your order may fill immediately.
To avoid this from happening, please make sure that the limit order that you will place is below the market price for buy limit orders and above the market price for sell limit orders.
