数字货币手动期现对冲策略

鉴于期现对冲策略对冲频率并不是特别高，实际上是可以手动操作的。但是如果纯手动去操作，切换各个交易所页面，观察价格，计算差价就很不方便，并且有时候还可能想多看几个品种，弄好几个显示器显示行情也是没太大必要。这样是不是用一个半自动的策略能实现手动操作的这个需求呢？最好还是多品种的，哦！对，最好还有一键开仓、平仓。哦！对，还要有仓位显示…

有了需求，马上动手！

设计一个数字货币手动期现对冲的策略

写的比较啰嗦，代码600行不到。

由于多品种策略比较适合使用IO来设计，所以代码中用到了名为MultiSymbolCtrlLib的一个模板类库（封装，通过IO调用交易所接口）。所以策略是不能回测的，不过可以用模拟盘测试（虽说实盘也跑了有2个月了，测试、熟悉阶段还是用模拟盘跑跑）。

参数

在上手测试之前首先说说参数设计方面。

策略参数不多，比较重要的参数有：

• 对冲控制表

  LTC-USDT-211231|LTC_USDT,BTC-USDT-211231|BTC_USDT
  

  这里就是设置策略都监控那些组合，例如以上的设置是监控期货交易所的莱特币合约（LTC-USDT-211231）和现货交易所的莱特币（LTC_USDT）。一个组合期货合约和现货交易对用|符号隔开，形成一个组合。不同组合使用,符号隔开。注意这里的符号都是英文输入法状态哦！
  那可能你问我合约代码要怎么找，这些合约代码、现货交易对使用的都是交易所定义的。并非FMZ平台上定义的。
  例如LTC-USDT-211231这个合约目前是次季度合约，在FMZ上叫next_quarter，OKEX的接口系统就是叫它LTC-USDT-211231。WexApp模拟盘对于莱特币/USDT交易对写法就是LTC_USDT。所以这里具体怎么填写，就看交易所里定义的名称。

• 交互控件对冲的对冲量
  点击状态栏控件按钮，对冲的量。单位是币数，策略会自动换算成合约张数下单。

  

其它的都是设置模拟盘、重置数据、使用OKEX V5接口（因为也兼容V3）等功能，不是特别重要。

测试

第一个交易所对象添加期货的交易所，第二个添加现货交易所对象。

期货交易所使用OKEX的V5接口模拟盘，现货交易所使用wexApp模拟盘。

点了下BTC组合的正套按钮，开仓了。

又点了下正套平仓。

亏了！！！看来利润差价小的时候平仓覆盖不了手续费，需要算下手续费、大概滑点，然后合理规划平仓的差价，再平仓。
