下面用一个实例来说明如何看技术分析图表， 我们以IBM过去六个月的交易为例：

先看看价格走势图：

Price
整个价格曲线图由一组每天一根的价格条来组成， 价格条通常用红色来画， 每一根价格条的最下端代表当天的最低价， 而它的最上端则代表当天的最高价， 每根价格条的右侧有一条小横线代表当天的收盘价。 如果收盘价接近于当天的最高价的话， 我们说这天是“牛”市(bullish)， 如果收盘价接近于当天的最低价的话， 我们说这天是“熊”市(bearish)。

5 EMA ( 5-day exponential moving averages )
13 EMA ( 13-day exponential moving averages )
50 EMA ( 50-day exponential moving averages )
上面这三条移动平均线代表了一支股票的大致走向， 最重要的是我们必须密切注意当前价格是位于13 EMA和50 EMA的上面还是下面.

Bollinger Bands
Bollinger Bands, created by John Bollinger, are a type of envelope (or trading band) plotted at standard deviation levels above and below a moving average. Because standard deviation measures volatility, the bands widen during volatile markets and contract during calmer periods.

In Achelis' Technical Analysis from A to Z (Chicago: Irwin, 1995), Bollinger has this to say about his indicator:
- Sharp price changes tend to occur after the bands tighten, after volatility lessens.
- When prices move outside the bands, a continuation of the current trend is implied.
- Bottoms and tops made outside the bands followed by bottoms and tops made inside the bands call for reversals in the trend.
- A move that originates at one band tends to go all the way to the other band. This observation is useful when projecting price targets.

Bollinger Bands, displayed in two bands plotted at standard deviation levels above and below a moving average, provide a view of the current trading range. They can be used with other indicators to determine when to buy or sell.
