Volume & Order Flow

AMT Delta Efficiency

Volume-to-delta conversion efficiency oscillator

Measures how efficiently volume converts into directional delta on both the bid and offer sides. Features smoothed efficiency lines, min/max swing levels, an efficiency midpoint, and crossover signals. Designed for volume charts with per-product volume settings.

AMT Delta Efficiency on a Sierra Chart

The Concept

Not all volume is equal — sometimes heavy volume produces a large delta (efficient conversion), and sometimes heavy volume produces little directional movement (absorbed by passive orders). Delta Efficiency measures how effectively volume translates into directional commitment on each side of the market. High offer efficiency with rising price confirms genuine buying pressure; low efficiency during a rally warns of potential absorption.

How to Read It

Two efficiency lines (bid in red, offer in cyan) oscillate relative to each other.

  • Offer Efficiency rising above Bid Efficiency = buyers are converting more volume into delta (bullish)
  • Bid Efficiency rising above Offer Efficiency = sellers are converting more volume into delta (bearish)
  • Cross-Up dots (cyan) mark bullish crossover — offer efficiency crosses above bid
  • Cross-Down dots (red) mark bearish crossover — bid efficiency crosses above offer
  • Max/Min lines lock in the prior swing's high/low efficiency for range context

Practical Tips

Place this on a volume chart (not time-based) for best results. Recommended volume settings per product: ES=1300, NQ=500, RTY=175, CL=375, GC=135. The MA Period smooths the raw efficiency ratio — shorter periods are noisier but more responsive. The efficiency crossover signals work similarly to MACD crosses but are purely order-flow based.

Input & Settings

1Efficiency MA Period

Smoothing period for the bid and offer efficiency ratios. Default: 14. Range: 1–200.

2Volume Setting

Volume setting for the chart. Product-specific; affects efficiency calculation precision. Default: 500.
