+
+### 简介
+OkCoin的比特币交易接口，基于Websocket API开发，实现了以下功能：
+
+1. 发送、撤销委托
+
+2. 查询委托、持仓、资金、成交历史
+
+3. 实时行情、成交、资金更新的推送
+
+### 特点
+相比较于[OkCoin官方](http://github.com/OKCoin/websocket/tree/master/python)给出的Python API实现，vn.okcoin的一些特点：
+
+1. 同时支持OkCoin的中国站和国际站交易，根据用户连接的站点会在内部自动切换结算货币（CNY、USD）
+
+2. 采用面向对象的接口设计模式，接近国内CTP接口的风格，并对主动函数的调用参数做了大幅简化
+
+3. 数据解包和签名生成两个热点函数使用了更加高效的实现方式
+
+### 参数命名
+函数的参数命名针对金融领域用户的习惯做了一些修改，具体对应如下：
+
+* expiry：原生命名的contract_type
+* order: 原生命名的match_price
+* leverage：原生命名的lever_rate
+* page：原生命名的current_page
+* length：原生命名的page_length
