# Average True Range Percent (ATRP)

## Average True Range Percent (ATRP) <a href="#average_true_range_percent_atrp" id="average_true_range_percent_atrp"></a>

The ATRP is a variation of the ATR indicator. ATRP measures volatility, similar to the Average True Range (ATR), but there's a difference. ATRP is scaled as a percentage, which means you can use it to compare ATR values of different securities.&#x20;

## Calculating ATRP

The ATRP is calculated by dividing the ATR by the closing price and multiplying the value by 100.

```
ATRP = (ATR / Close) * 100
```

## The Bottom Line <a href="#the_bottom_line" id="the_bottom_line"></a>

ATRP is not a directional indicator like MACD or RSI. Instead, it's a unique volatility indicator that reflect the degree of interest or disinterest in a move. Large ranges or True Ranges often accompany strong moves in either direction, which can be volatile. This is especially true at the beginning of a move. Relatively narrow ranges can accompany low-volatility moves. ATRP can validate the enthusiasm behind a move or breakout. A bullish reversal with increased ATRP would show strong buying pressure and reinforce the reversal. A bearish support break with increased ATRP would show strong selling pressure and reinforce the support break. The ATRP can help you compare the ATR of different securities to determine which securities are more volatile than others.

## Charting with ATRP

### Using with StockChartsACP <a href="#using_atrp_with_stockchartsacp" id="using_atrp_with_stockchartsacp"></a>

In StockChartsACP, you can [view multiple charts simultaneously](https://help.stockcharts.com/charts-and-tools/stockchartsacp/multi-chart-layouts-in-stockchartsacp), making it simpler to compare the ATRP for different securities. For example, to compare the ATR for four semiconductor stocks, select the four chart layouts in StockChartsACP and add the four symbols. The example below shows a chart of Advanced Micro Devices (AMD), Intel Corp. (INTC), NVIDIA (NVDA), and Micron Technology (MU). You'll notice that out of the four stocks, AMD and NVDA are more volatile than INTC and AMD.
