现货白银点差怎么算
关键词：现货白银点差怎么算
在现货白银的报价中，买入价与卖出价之间有一个差价，其中买价会较高，卖价会较低，这个差价是我们常说的点差，是在建仓的一刻，系统自动收取的费用，该费用是做市商的利润。那么这个点差是怎么计算的呢？现在，小编就为大家讲一讲。
一、什么是点？
在金融市场中，点是对投资产品非整数价格公布对最后一位小数的描述。在如现货白银市场中，白银报价目前报价为16.703美元/盎司，最后一位小数是3，就被称为3点，若白银价格随着市场变化运行到16.683美元/盎司，那么银价就波动了20个点。
二、点差怎么算
1、点差计算公式
点差是买入价与卖出价的差值，因此点差的计算公式为：
点差=买入价-卖出价
2、点差的计算
假设目前现货白银报价为买入价16.760美元/盎司、卖出价16.730美元/盎司，那么点差=16.760-16.730=0.030美元/盎司。
一手现货白银2500盎司的点差就是0.030×1×2500=75美元。
三、为什么会存在点差
因为现货白银有一个做空机制，即买跌都能买涨那样获得盈利，但是交易所不会无利益给大家提供一个平台让大家赚钱，因此就有了点差这个说法，这个点差就是给予交易所的利润，同时也是交易所的一个防控措施，避免出现刚刚下单就平单的刷手数情况。另外，由于点差是每一次的交易都会收取的，因此累积的金额会很大，那么当市场出现危机的时候，其存在就成为解决危机的关键之一。因此，点差的存在对于现货白银的投资来说是必要的。
