困惑我很久的价格单位终于弄明白了

in cn •  7 years ago  (edited)

这篇可能又会是一篇比较晦涩的文章了。可能也许写完了也就只有我自己能看懂了吧。。

在没有开发恒星做市机器人之前，一直都没有仔细关注过交易市场的价格单位。

由于交易市场之前都是 CNY 和具体的数字货币交易，所以交易所显示的价格都是买一个数字货币需要多少 CNY，我只需要看具体的数值即可，并不影响我判断什么时候买入，什么时候卖出。

在开发第一版的机器人的时候，由于只是在单网关下做 XLM 和 CNY这一个交易对，也就没有在意价格单位的问题。

但是从开发第二版机器人开始，由于加入了多网关多币种之间互相做市的功能，就不得不看看具体的单位到底代表什么意思了。

之前每次扫到类似 BTC/CNY 这样的单位的时候，总以为这是个分数，比如 60000 BTC/CNY 我会以为是每一个 CNY 可以买到 60000 个 BTC，由于这个例子使用的是 CNY ，我们心里清楚目前 BTC 值多少 CNY，因此才知道我刚才的阅读单位的方式是错误的。

目前我开发机器人过程中，会出现两个陌生币种之间的交易，这个时候，如果不能真正了解价格单位的意义，开发出来的机器人肯定会是有问题的。

所以到底类似 BTC/CNY 这样的交易对价格单位该如何正确解读呢？

在说正确方法之前，还要再插一句，就是 BTS 内盘的价格单位其实在很长一段时间都是给我有误导作用的。我们看一下在内盘抵押 BTS 的时候，出现的喂价和强平触发价的单位。

这里的单位就真的是分数式的解读啊！比如强平触发价 2.97143 BTS/bitCNY，就是当 1 个 bitCNY 可以买到 2.97143 个 BTS，也就是 1 个 BTS 值大约 0.3365 bitCNY 的时候爆仓。

下面就来说下到底该如何解读交易所的交易对的价格单位。

我以 base currency and counter currency 作为关键词，在 Google 上搜索了下，发现了这个解释 https://www.investopedia.com/terms/b/basecurrency.asp。

简单来说，这是外汇市场的一个约定俗成的表示方法，而 不是 一个分数形式的表示，只是通过先后顺序来表示关注程度。一个交易对的价格使用类似 base currency/counter currency 的格式来表示，意味着我更关注 base currency 的价值是升了还是跌了，也就是我买一个 base currency 要花多少 counter currency 或者 卖一个 base currency 能得到多少 counter currency。就是这么简单的按照顺序阅读即可。

举个例子，比如说 BTC/CNY 这个交易对，之前 60000 BTC/CNY 应该解读为我购买 1 个 BTC 需要花费 60000 个 CNY，如果购买一天后价格变为了 70000 BTC/CNY，就意味着我关注的这个 base currency 即 BTC 升值了。

总结一下，其实 counter currency 就是你手里的筹码。base currency 是你想持有的。

这样一来，你关心哪个币的涨跌，就把哪个币设置为 base currency 就可以轻松的了解是否升值了。

以上就是完整的价格单位如何解读的内容了，下面是吐槽内容，选读：

除了恶心的价格单位外，再说一下 bid 和 ask，这个也是让我头疼的东西。
放狗搜索了下，发现了这篇文章，https://www.bitcoinmarketjournal.com/difference-bid-ask-buy-offer-cryptocurrency-trading/，发现老外也真是够了。
原来 bid price 代表了最高的买价，ask price 代表了最低的卖价，而 buy price 和 sell price 只是代表最终的成交价。。。
WTF，为啥要多搞出来两个名词，对于中文来说都是买价卖家，无非加上最低和最高这样的形容词罢了。。。
我还要吐槽的是，恒星币的接口返回的 orderbook 里用 buy 和 sell 来表示买单列表和卖单列表并没有不严谨吧，反而用的是 asks 和 bids 来表示卖单列表和买单列表。每次我都是要反应半天！只能说还是我的英语学的不好。
说到 orderbook，又想起了另外一个槽点，就是在恒星币的 API 体系里清一色的都是 offer，而这里却是 orderbook，你咋不叫 offerbook 呢？
吐槽完毕！

                              It's easy to get starting with one day. If you want to learn a framework, like Vue.js, it may take about 1 to 3 months.
