What is the wheel score used in the OptionIncomeTools wheel screener?

The wheel score is a 0–100 composite that ranks an underlying for the wheel strategy by combining annualized yield, liquidity, delta quality, and implied-volatility regime; it is a screening heuristic, not a forecast.

Calculation type: Heuristic score Method version: 2.0 Effective date: 2026-07-16 Date reviewed: 2026-07-16

Formula

A weighted linear combination of four sub-scores (each normalized to 0–1), returned on a 0–100 scale:
  40% × yield (min(1, combinedYield / 1.5))
  25% × liquidity score (0–1)
  20% × delta quality (peaks at delta = 0.27; falls off linearly)
  15% × IV regime (penalty applied when IV > 80%)

Reference implementation: wheelScore() in worker/src/index.js. This page is generated from the canonical scoring registry — if the code diverges from these weights, the deployment lint (Preflight Gate 13) will fail the build.

Worked example

SOFI shows an annualized combined yield of ~45% (yieldNorm = 0.30), a liquidity score of 78 (liqNorm = 0.78), a short-put delta of 0.30 (deltaQ = max(0, 1 − |0.30 − 0.27| × 2) = 0.94), and IV of 55% (ivPenalty = 1.0 because IV < 80%). Composite: 0.40(0.30) + 0.25(0.78) + 0.20(0.94) + 0.15(1.0) = 0.65 × 100 = 65.

Common misinterpretation

Treating wheel score as a quality score or a prediction of profit. It is a relative ranking inside our screened universe under the current snapshot. A wheel score of 75 today may be 55 tomorrow if implied volatility falls or assignment risk rises.
