   Filter out what cannot be traded cleanly

   Baseline quality rules run before anything is scored. This removes illiquid, far-dated, deep out-of-the-money and wide-spread contracts that can look cheap but are hard to get in and out of.

   Score what survives

   A base value, then points added or subtracted for chain quality and catalyst context. The weights below are the maximum each input can contribute.

   Gamma / $18 pts Convexity per dollar of premium — more potential movement for the price paid.

   Fresh flow16 pts Volume against open interest. Volume above OI suggests new positioning rather than churn.

   Liquidity12 pts Higher volume, so the contract is actually executable.

   IV rankweighted Lower implied volatility is rewarded — cheaper vol leaves more room for expansion.

   Catalystsadjusts Filings, analyst target changes, insider activity, earnings timing, news sentiment, macro risk and repeat flow can move the final score either way.

   Promote only the cleanest to the header cards

   The top cards run stricter rules than the table below them. They are meant to show clean, directional setups — not everything that passed the scanner.

   Threshold	Why it is there
   Score ≥ 80	Keeps weak setups out of the header entirely.
   IV rank ≤ 35	Prioritises lower-priced volatility.
   V/OI ≥ 2×	Requires meaningful fresh demand, not routine volume.
   Side bias ≥ 70%	The ticker’s premium bias must match the contract side.
   Gamma/$ ≥ 0.002	Keeps genuine convexity in the setup.
   $ flow ≥ $15K	Filters out prints too small to mean anything.

ConvexRadar is research software. These rules describe how contracts are ranked for review — they are not a prediction of direction and not a recommendation to trade. Options trading involves risk, including total loss of premium.
