Ninja Trader Supplied Indicators

ATR Indicator

ATR Indicator

The Average True Range (ATR) Indicator on NinjaTrader is a technical analysis tool used to measure market volatility. It was developed by J. Welles Wilder Jr., the creator of several trading indicators, and it's particularly useful in providing insights into the degree of price volatility over a given period.


Here's how the ATR works:

1. Calculation:

- The ATR calculates the "true range" for each period, typically a day for daily charts. The true range is the greatest of the following:

- The difference between the current high and the current low.

- The difference between the previous close and the current high.

- The difference between the previous close and the current low.

- The ATR is then the moving average (usually a 14-day period) of these true range values.


2. Purpose and Interpretation:

- Measuring Volatility: The primary function of the ATR is to measure the volatility of a market. Higher ATR values indicate greater volatility, while lower values suggest less volatility.

- Non-Directional: The ATR does not indicate the price direction, only the volatility level.

- Adaptive to Market Conditions: It adapts to changes in volatility over time, making it useful for adjusting trading strategies according to market dynamics.


3. Use in Trading:

- Setting Stop Losses: Traders often use the ATR to place stop-loss orders. For example, a stop loss might be set at a certain multiple of the ATR below the current price for a long position.


- Position Sizing: The ATR can help in determining the appropriate position size based on market volatility.

- Entry/Exit Points: Though not a directional indicator, the ATR can inform traders about the best times to enter or exit trades based on the current volatility.


4. NinjaTrader Platform:

- On NinjaTrader, the ATR is available as one of the standard indicators. Traders can apply it to their charts and customize the period settings (e.g., 14-day ATR) to suit their trading strategy and analysis needs.


5. Limitations:

- The ATR is a lagging indicator, meaning it is based on past price data and might not accurately predict future market movements.

- It should be used in conjunction with other analysis tools to make more informed trading decisions.
