FAQ

Questions Mass Index Calculator owners ask.

  • 01

    What is the Mass Index?

    The Mass Index is a momentum oscillator that identifies market reversals by measuring volatility compression using smoothed price ranges.

  • 02

    How do I detect a reversal?

    You can use the detect_reversal_signals capability to identify when the Mass Index crosses above the upper threshold and subsequently falls below the lower threshold.

  • 03

    What is a bulge formation?

    A bulge is a period of sustained high Mass Index values, which can be identified using the identify_bulge_formations capability.
