Parameter
 Explanation
minerFee
This value is for deposited tokens that utilize SWFTC for the exchange fee, SWFTC exchange fee = deposited amount * minerFee
receiveCoinFee
 This value is the amount of network fee deducted after successful transfer, the units are displayed in the token type the user is receiving/buying, this can be used to calculate the approximate amount of tokens that the user will receive, or it will be used to display the amount of network fees deducted to complete the transfer.
Important Items：
 For advanced trading, user's fee method is the deposited tokens, not SWFTC, therefore parameter "minerFee" can be ignored, the transaction fee is fixed at 0.1% (ex.: if depositing 0.1 BTC, the actual amount deducted is 0.0001btc as the transfer's transaction fee, when actually exchange, only 0.0999btc will be transferred)
