Fractional-Bar Quick Moving Average: Weighted Smoothing and Overshoot

Summary

The document introduces the Fractional-Bar Quick Moving Average (QMA), a price-smoothing indicator presented as comparable to a Jurik moving average. It describes the QMA as both smooth and fast, while warning that it can overshoot substantially, which may make it unsuitable in some situations. The included indicator method applies a triangular weighting profile across a configurable lookback and divides the weighted price total by the sum of the weights; if the denominator is zero, it falls back to the current series value.

The source says the implementation was translated from a MultiCharts version for use in ProRealTime and sets the example period to 50. It supplies no chart, comparison study, performance test, or evidence establishing how QMA behaves across markets or parameter settings. The stated speed and smoothness are qualitative, and overshoot is the main caveat. Traders considering the indicator would need to assess lag, overshoot, and signal behavior on their own data before using it in a strategy.

Key ideas

• QMA uses a weighted average with a triangular weighting profile across its lookback.
• The example uses a period of 50 and applies the calculation to a price series.
• The author characterizes the indicator as smooth and fast, but offers no comparative test.
• Substantial overshoot is identified as a potential drawback.
• The implementation is a translation from MultiCharts for ProRealTime.
