ATR (Average True Range) plays a very important role in deciding stop-loss levels in trading. ATR tells us how much a stock or asset usually moves in a day. When we know this, we can set a stop-loss that is not too close (to avoid being triggered by normal movements) and not too far (to protect capital). This helps traders manage risk properly and stay in trades without getting stopped out too early.
What is ATR in Trading?
ATR stands for Average True Range. It is a technical indicator that shows how much a stock or asset moves, on average, in one day. It does not show direction (up or down), but only tells how volatile the stock is. A higher ATR means more movement, while a lower ATR means the stock is more stable.
Traders use ATR to understand market volatility and set stop-loss levels that match the stock’s behavior.
How Does ATR Help in Setting Stop-Loss?
ATR helps you avoid setting stop-loss levels that are too close or too wide. If your stop-loss is too tight, normal price movement can hit it and remove you from the trade. If it is too far, you risk losing more money.
By using the ATR value, you can place your stop-loss at a logical distance, based on how much the asset usually moves. This way, you stay in the trade while still protecting your capital.
How is ATR Calculated?
ATR is calculated using the following steps:
- First, calculate the True Range (TR), which is the highest of:
- High - Low
- High - Previous Close
- Low - Previous Close
- Then, ATR is the average of the True Ranges over a period, usually 14 days.
Most trading platforms automatically calculate and display ATR, so traders just need to look at the chart.
What is a Good ATR-Based Stop-Loss Strategy?
A common method is to set the stop-loss at 1 to 2 times the ATR value below the entry price for long trades, and above the entry for short trades.
Example: If you buy a stock at ₹100 and ATR is ₹2, a 1.5 ATR stop-loss would be ₹97 (₹100 - ₹3). This gives the trade enough room while managing your risk.
This strategy adjusts with the market, so your stop-loss is dynamic based on volatility.
Why is ATR-Based Stop-Loss Better Than Fixed Points?
Fixed point stop-loss levels do not consider how much a stock normally moves. If the stock is very volatile, a fixed stop-loss might get hit too soon.
ATR-based stop-loss is better because it changes based on the stock’s current behavior. It adapts to the market conditions and gives you a smarter, more logical risk control.
Can ATR Be Used in Intraday Trading?
Yes, ATR is very useful in intraday trading. It shows how much a stock is likely to move in a day, so traders can plan their entries, targets, and stop-loss accordingly.
Intraday traders often use 5-day or 10-day ATR to set tighter stop-loss levels based on short-term movements.
