By Daniel P. Collins\u00a0<\/a><\/strong><\/p>\n There are various technical trading indicators to help traders build technical systematic trading strategies. Some, such as the <\/span>Moving Average Convergence Divergence (MACD)<\/span><\/a> indicator, are better as a standalone signal generator. In contrast, others, like <\/span>the Relative Strength Index (RSI)<\/span><\/a>, work best as a filter or overlay with other indicators or systems.\u00a0<\/span><\/p>\n Every indicator is based on some sort of mathematical model or average and provides valuable data. The important thing for traders is to understand what they are showing and what they aren\u2019t. They are not predicting moves but providing specific data that can be studied to find tendencies in the market that can be used to create an edge.\u00a0<\/span><\/p>\n The beauty of most indicators is in their simplicity. This is especially true with the Average True Range (ATR). The ATR falls into the category of a filter or overlay indicator that can be used to measure momentum, trend, and, most of all, volatility.\u00a0<\/span><\/p>\n It is simply an average of the previous period\u2019s (usually 14) true ranges.\u00a0<\/span><\/p>\n Calculation<\/strong><\/p>\n ATR = (Previous ATR * (n – 1) + TR) \/ n<\/span><\/p>\n Where:<\/span> The True Range is the greatest of the following:<\/span><\/p>\n The true range calculation can include the previous day\u2019s close when there is a gap opening.\u00a0 David Wilder explained, \u201cIn this way, both directional and non-directional movement can be captured and quantified, while gap openings are properly accounted for (see \u201cUnlocking the volatility key using ATR,\u201d Futures, December 2008).\u00a0<\/span><\/p>\n Its creator, J. Welles Wilder, wrote, “The one thing that is directly proportional with volatility is range.”<\/span><\/p>\n While there are some much more complicated measures of volatility, the beauty of ATR is in its simplicity. For example, the Cboe Volatility Index (VIX)\u2014the standard measure of volatility for equity markets, which uses a complex combination of options prices to calculate volatility\u2014often doesn\u2019t show upside volatility. Since futures (which Wilder designed ATR for) has no bias between long and short positions, the simplest measure of volatility is the size and trends of market ranges over time.\u00a0<\/span><\/p>\n Ironically, Wilder built his trend-following Volatility System primarily off of readings of the ATR. Today most traders use it in concert with order indicators to help select entries and exits, gauge risk within a trade, and to set stop levels.\u00a0<\/span><\/p>\n
