  • $.getAmountPrecision(Currency)

交易对基础币种计数精度(小数点后位数) 返回值 number类型

  • $.getPricePrecision(Currency)

交易对报价的精度(小数点后位数) 返回值 number类型

  • $.getMinOrderAmount(Currency)

交易对最小下单量 返回值 number类型

  • $.getMaxOrderAmount(Currency)

交易对最大下单量 返回值 number类型

  • $.getValuePrecision(Currency)

交易对交易金额的精度(小数点后位数) 返回值 number类型

  • $.getMinValue(Currency)
