Evaluate futures liquidity before contract selection
A listed-futures ranking multiplies contract point value, a three-year maximum price motion, open interest, and a volume adjustment so each candidate can be compared on a shared dollar, activity, and margin scale before a contract is chosen.
- A listed-futures liquidity ranking multiplies contract point value, a three-year maximum price motion, open interest, and a volume adjustment so candidates can be compared before a contract is chosen.
- Equal-dollar contract count uses tick dollar value and the three-year maximum price excursion so different futures sit on one potential dollar scale.
- Open interest is applied after that scaling, and a volume factor reduces thin activity and raises heavy activity, with a floor at one.
- Effective percent margin and other column scores are proportional and can be read only against other contracts in the same column.
Judge a contract by whether a comparable exposure can be implemented
A listed-futures liquidity ranking can be formed by multiplying contract point value, a three-year maximum price motion, open interest, and a volume adjustment for unusually thin or heavy activity.
Futures contract selection then means choosing among listed futures by placing each market on a shared dollar-profit and margin-efficiency scale instead of treating every contract as interchangeable.
Posted vs effective percent margin, June 2020 futures list

The source ranks rows by relative contract liquidity (contracts-to-trade times open interest times a volume factor). That composite is not printed as a number, so this chart keeps the published row order and plots the two margin columns. Effective percent margin uses a three-year lookback.
Form one ranking from size, range, and activity
Relative contract liquidity is a descending comparison score equal to the equal-dollar contract count times total open interest times a volume factor. The volume factor is an activity adjustment, typically in a narrow integer band and floored at one, that reduces very thin volume and raises very heavy volume.
Relative activity marks order contracts so the most marked markets are treated as easier to buy and sell, while a single mark or none indicates thin activity. A liquidity filter keeps contracts whose size, historical range, activity, and costs imply they can be entered and exited, and sets aside names whose activity marks show a thin book.
Scale open interest to a common dollar exposure
An equal-dollar contract count is tick dollar value times the three-year maximum price excursion, so different futures can be compared at a common potential dollar scale. It states how many contracts of one future must be traded to match another future's three-year dollar price excursion.
Open interest analysis weights how easily a market can be traded by outstanding contract inventory, after scaling for how many contracts are needed to match a common dollar exposure.
Compare margin intensity only inside its column
Effective percent margin is posted margin dollars divided by the contract's three-year dollar range, expressed as a percentage so margin intensity can be compared across markets with different ranges.
Each liquidity or margin column is a proportional score that is interpretable only against other contracts in the same column.
In listed shares, period volume as a percentage of shares outstanding is used as a turnover-rate proxy for trading liquidity. Editorial: that share-turnover proxy is a listed-share stand-in for trading liquidity. It is not the futures ranking described here.
