What Is ATR and Why Should Traders Follow It?

Any stock for Example

ATR (Average True Range) is a technical indicator developed by J. Welles Wilder that measures the average volatility of a stock, index, commodity, currency, or crypto asset. Unlike indicators that predict whether price will go up or down, ATR tells traders how much an instrument typically moves over a given period. For example, if a stock has an ATR of ₹20, it indicates that the stock has been experiencing an average daily movement of roughly ₹20. A higher ATR means higher volatility, while a lower ATR indicates relatively calmer price action. Traders should follow ATR because volatility is essential for setting realistic Stop Losses and Targets. A Stop Loss placed too close to the entry can get triggered by normal market fluctuations even when the trade direction is correct. ATR helps traders give the trade enough breathing room according to the instrument's actual volatility. ATR can also help with position sizing and risk management. When volatility increases, traders can reduce their position size to keep the rupee risk under control. When volatility decreases, position size can potentially be adjusted accordingly. Another important use is identifying unusually strong price movement. If a stock moves significantly more than its normal ATR, it may indicate increased momentum, news-driven volatility, or a potential breakout. However, ATR should not be used alone to decide BUY or SELL trades. It works best alongside price action, support and resistance, trend, volume, moving averages, and momentum indicators. In simple words: ATR tells you how much the market is moving, helping you decide where to place your Stop Loss, Targets, and position size more intelligently.
