The BigDipperOptions score is a composite metric at each strike or spread. It summarizes where positioning, volatility, and participation cluster—not whether a trade is “good,” “bad,” or likely to profit.
Not a trade signal. In the Learn track, score is a tie-breaker for attention, never a reason to enter. See Wheel Module 3.

​
What goes into the score

The score blends many strike-level inputs, including (not limited to): BigDipperOptions is built to make options research easier than scanning dozens of raw broker columns (IV, IV Rank, OI, delta, gamma, volume, …) strike by strike. Instead, IV and the other inputs above are combined into one score so you can compare strikes and shortlist faster. A higher score means more combined engagement at that level relative to other strikes—not a higher win rate.

Score on BigDipperOptions, then your broker

Typical workflow: narrow and compare here first → confirm live details at your broker before any order.
Chart data on BigDipperOptions is delayed. Score already blends IV with OI, gamma, and other signals for screening. Your broker is where you verify live vol and prices right before you trade.
Common mistake: jumping straight to broker chains and sorting IV/OI/delta manually when score + Wheel filters already narrowed the field—or the reverse, placing an order from a high score without a live broker check.

​
Score scale

Score is a decimal (not 0–100). On a given symbol and refresh, values typically run from 0 up to roughly 5–6—the exact ceiling depends on the name and how much activity is in the chain. The number under each strike on the bias heatmap is the score for that cell—darker green (calls) or pink (puts) means a larger magnitude on the legend scale. Compare scores relative to other strikes and expiries on the same symbol, not to a fixed “good” threshold.

​
How to read the bands

Use score for relative comparison on the same symbol—not as standalone buy/sell zones. Bands below assume a typical ceiling near ~5.5; your heatmap legend shows the live max for that chain.
The score is experimental and continually refined. Use it on BigDipperOptions for screening, then GEX, walls, and your Module 3 checklist—and confirm live IV and quotes at your broker before you trade.
