Let's go through an example of an order, worth 0.001 BTC.
The first line displays a 3% service fee. The second line displays a non-refundable new order fee of 0.00001 BTC. The third line displays the amount that was used to pay for your shares. So the total amount of your order is the SUM from these three lines.
Detailed calculation breakdown:
0.001 - non-refundable new order fee 0.00001 BTC = 0.00099 (amount after order submission)
0.00099 - service fee 3% (0.0000297) = 0.0009603 (paid for your shares)
0.00001 BTC + 0.0000297 = 0.0000397 (total fees)
