DepthHouse Volume Flow indicator is used to help determine trend direction strictly based on Negative and Positive volume data.

How to Read:

  • Moving Average crossovers are used to help determine a possible trend change or retracement.
  • The area cloud on the bottom is calculated by the difference of the moving averages. This could be used to help determine the trending volume strength.
  • Bright colored volume bars are large volume spikes calculated by the x factor in the options.

Other changes:

  • DepthHouse is going open source with numerous of its indicators. This is only one of many!
  • Volume is now displayed without being altered for calculations.
