区班量化

> Strategy Description

前面文章讨论过，小卖部策略在特定情况下，可以做到130%的年化收益。不过这是在特定情况下，就是该商品的月度均线，从长期看是上升的，且经过了很长一段时间。如果在进入市场的短期3个月里，都处于下跌市里，那可能遭到重大打击。
究其原因，最重要的是，该策略没引入做空机制。犹如在A股市场里，只能做多，那下跌来时，只能空仓或者被动挨揍。还好数字货币是提供做空机制的，通过合约交易，我们就可以把下跌风险规避掉。
今天区班主做的策略是牛熊小卖部策略。主要思想是牛市来了，就做多，同时抬高公允价格的预期；熊市来了，就做空，同时降低公允价格的预期。猴市来了则高抛低吸。牛熊猴的判断参考之前的文章，就是以短期高低点和长期高低点的关系，决定当前市场状态。
本策略应用于ETH，这里需要指出两个坑：1、本策略基于ETH，ETH在OKex期货里，是10刀一张的；需要BTC的朋友请自己修改一下除数；2、合约下单后，如果是相同多单，会合并成一个Position，所以Position的长度最多为2，这也是导致区班主当时反复调试的地方，还好最后解决了。
