一些交易者成功地使用和精通其中一些指標。
The red line on the chart is called a Bollinger Band. It is two standard deviations above the 20-day moving average. This is important because according to statistics and probability theory, 95% of all trading should be within two standard deviations of the mean.
圖表上的紅線被稱爲布林帶。它是20日移動平均線的兩個標準偏差。這很重要，因爲根據統計學和概率論，95%的交易應該在均值的兩個標準偏差範圍內。
If a stock exceeds this threshold, as Expedia has done, it will draw sellers into the market. They will be expecting a reversion back towards the average and their selling could put pressure on it.
如果一支股票超過這個閾值，就像Expedia所做的那樣，它會吸引賣家進入市場。他們會預計價格會回歸到平均水平，他們的賣出可能會給股價施加壓力。
