Quant Force: an adaptive baseline built on Kaufman's Efficiency Ratio

How a baseline that reacts to the character of a move — not a fixed lookback — filters chop before it reaches the confluence layer.

Abstract

Fixed-lookback moving averages face an unavoidable dilemma: fast enough to catch moves means whippy in chop; smooth enough to ignore chop means late to moves. Quant Force sidesteps this by adapting its responsiveness to Kaufman's Efficiency Ratio, then wrapping the baseline in an ATR envelope and confirming direction only after a configurable run of closes beyond the band. This paper describes the construction and the noise-rejection logic.

01The fixed-lookback dilemma

A 10-period average is responsive but noisy; a 50-period average is smooth but late. No single fixed lookback is right across regimes, because the market's character changes — trending one week, ranging the next. The baseline needs to adapt to that character rather than to the calendar.

02Kaufman's Efficiency Ratio

The Efficiency Ratio (ER) measures directional movement relative to total path length over a window: net change divided by the sum of absolute bar-to-bar changes. ER near 1 means a clean, directional move; ER near 0 means the market covered a lot of ground going nowhere. Quant Force uses ER to scale a smoothing constant, so the baseline accelerates and hugs price in efficient moves and flattens in chop.

03The ATR envelope and confirmation run

The adaptive baseline is wrapped in an envelope scaled by Average True Range, so the band widens in volatile conditions and tightens in calm ones. A directional flip is only confirmed after a configurable number of consecutive closes beyond the band — single-candle pokes are rejected before they ever reach the confluence layer.

04Where it sits in the pipeline

Quant Force is one of the six Confluence checks and also contributes to the Quality gate through its efficiency reading. It is deliberately upstream: by filtering single-candle noise at the baseline, it reduces the false starts the rest of the pipeline would otherwise have to handle.

// Key findings

  • 01Fixed-lookback averages cannot be simultaneously fast and smooth across regimes.
  • 02The Efficiency Ratio scales responsiveness to the character of the move.
  • 03An ATR envelope adapts band width to volatility.
  • 04Confirmation requires consecutive closes beyond the band, rejecting single-candle noise.

Frequently asked

Is Quant Force just a moving average?

It is an adaptive baseline: its smoothing changes with Kaufman's Efficiency Ratio, and its direction only confirms after consecutive closes beyond an ATR-scaled envelope. That noise-rejection step is the key difference from a plain MA.

What is the Efficiency Ratio?

Net directional change divided by the total path length over a window. Near 1 = clean trend; near 0 = choppy. It is used to scale how tightly the baseline tracks price.

Why an ATR envelope?

So the confirmation band adapts to volatility — wider when the market is volatile, tighter when calm — instead of using a fixed distance.
