# 平台费用规则

## 费用计算规则：

* 未匹配的交易不收取上架或下架费用。
* 交易费用率：交易双方的交易量收取 2% 的交易费用。 
* 现金提取费用率：现金提取量收取 0.5% 的费用。
* 退款费用率：当双方未能执行结算时，退款量收取 0.5% 的费用。

## 计算公式：

* 匹配订单的买卖双方交易费用

                                                            交易费用 = 2% × 交易量

* 只有一方结算的匹配订单交易费用

                                                           交易费用 = 2% × 交易量（买家 + 卖家）

* 对于买卖双方未执行结算的交易（按抵押资产计算）

                                                            退款抵押费用 = 0.5% × 交易量

* 对于现金提取订单：

                                                            现金提取费用 = 0.5% × 交易量
