AM Detector is a technical indicator that singles out the amplitude modulation component out of the market data spectrum. Based on signal processing techniques, this indicator can help estimate current volatility.

AM Detector is calculated as follows:

  1. The absolute value of the difference between the close and open is calculated for each bar during the indicator period.
  2. The highest calculated absolute value is registered.
  3. The result is smoothed with a moving average of choice (by default, simple moving average).

AM Detector values are always positive. High readings of AM Detector may signify strong volatility.
