Stock Of The Day: Two Indicators Suggest Proctor And Gamble May Have Reversed
Stock Of The Day: Two Indicators Suggest Proctor And Gamble May Have Reversed
Trading models typically contain a set of parameters or conditions that must be met to give trade signals. Some human traders may only use one or two in their models while some quantitative ones may use hundreds.
交易模型通常包含一組參數或條件，必須滿足這些參數或條件才能發出交易信號。一些人工交易者在他們的模型中可能只使用一兩個，而一些量化交易者可能使用數百個。
On the Procter & Gamble Co (NYSE:PG) chart, two possible parameters can be used as part of a model: the Bollinger Bands and the RSI Indicator. This makes it our "Stock of the Day."
在寶潔公司（紐約證券交易所代碼：PG）圖表上，可以使用兩個可能的參數作爲模型的一部分：布林帶和相對強弱指數指標。這使其成爲我們的 「每日股票」。
The red line on the price chart is a Bollinger Band. It is two standard deviations above the 20-day moving average.
價格圖表上的紅線是布林帶。它比20天移動平均線高出兩個標準差。
This is important. Standard deviations are a statistical concept and many trading algorithms and strategies are based on statistics and probability theory. And they suggest that 95% of all trading should be within two standard deviations of the mean.
這很重要。標準差是一個統計概念，許多交易算法和策略都基於統計和概率論。他們建議，所有交易的95％應在平均值的兩個標準差以內。
If a stock exceeds this threshold to the upside like Proctor and Gamble, it is considered overbought. This will draw sellers into the market because they expect a reversion to the mean or a move lower.
如果某隻股票像寶潔公司一樣超過這個上行門檻，則被視爲超買。這將吸引賣家進入市場，因爲他們預計會回歸均值或走低。
Their selling could push the stock lower. It could be a self-fulfilling prophecy.
他們的拋售可能會推動股價走低。這可能是一個自我實現的預言。

The bottom half of the chart is the Relative Strength Index (RSI). This is another tool that traders use to determine if a stock is overbought. If the blue line exceeds the horizontal red line, it indicates overbought conditions. This could also draw sellers into the market.
圖表的下半部分是相對強度指數（RSI）。這是交易者用來確定股票是否超買的另一種工具。如果藍線超過水平紅線，則表示超買情況。這也可能吸引賣家進入市場。
A possible trading signal to sell could be when the Bollinger Bands and the RSI simultaneously show a stock to be overbought.
可能的賣出交易信號可能是布林帶和相對強弱指數同時顯示股票處於超買狀態。
As you can see on the chart, in late April the stock's price exceeded the upper Bollinger Band. However, the RSI did not indicate overbought conditions. This means there would have been no sell signal.
正如你在圖表上看到的那樣，4月下旬，該股的價格超過了布林帶的上限。但是，RSI並未顯示超買情況。這意味着本來不會有賣出信號。
Earlier this month the price exceeded the upper Bollinger Band but RSI did not move above the horizontal line. This means there was no reversal or sell signal.
本月早些時候，價格超過了布林帶上限，但RSI並未突破水平線。這意味着沒有反轉或賣出信號。
On Sept.10, both indicators showed the stock to be overbought at the same time. And as you can see, it looks like a reversal has begun and a move lower could follow.
9月10日，這兩個指標都顯示該股同時處於超買狀態。正如你所看到的，反轉似乎已經開始，隨後可能會走低。
Using two parameters to trigger sell signals can be a profitable way to trade. The chart of Proctor and Gamble is an illustration of this.
使用兩個參數觸發賣出信號可能是一種有利可圖的交易方式。寶潔公司的排行榜就是一個例子。
