In dynamic display board, “changes” is also an indicator that traders often pay attention to.
In the stock market:
changes = (latest price - yesterday's closing price) / yesterday's closing price * 100%
But, In the futures market:
changes = (latest price - yesterday settlement price) / yesterday settlement price * 100%
The settlement price is not the transaction price corresponding to a certain moment, it is calculated by weighted average.
【example】
The weighted average of the first 10 minutes is calculated as follows:
Weighted average = (10.2*50+10.3*40+10.6*70+...9.8*80)/(50+40+70+...80)
Calculation result ≈ 9.846
In the setting of many trading analysis software, the calculation method of the "changes" can be adjusted (using the closing price of the previous trading day as the benchmark or the settlement price of the previous trading day as the benchmark), and the trader can conveniently use it.

在前面的文章中,交易者了解到股票指数包含了两个因素,一个是样本股,另一个是计算方法。随着时间的推移,股票指数不可避免的会碰到一个棘手的问题:某些样本股对应的上市公司由于各种原因停止交易或者退出市场,这对指数存在的连续性提出了考验。这里以道琼斯工业平均指数(DJIA)为例,进行详细...
