Evaluate futures liquidity before contract selection

Contract choice as an execution exam

TradersWeek editorial reading: contract choice is an execution exam. Convert a three-year range into an equal-dollar contract count, then let open interest and a volume factor decide whether that size is bookable. A market is eligible only when the book can carry the implementation implied by its own history.

A listed-futures liquidity rank can be formed by multiplying contract point value, a three-year historical maximum price move, open interest, and a volume adjustment usually set between 1 and 4.

Build an equal-dollar unit

An equal-dollar column multiplies contract value by the largest price change observed in the prior three years so every entry in that column represents the same dollar unit.

The contracts-to-trade count equals tick dollar value times the three-year maximum price excursion. That count is the equal-dollar unit: the number of contracts required to match the same three-year historical dollar swing as other listed markets.

In this workflow, futures contract selection means choosing among listed markets and expiries only after candidates have been restated on one equal-dollar unit and ranked by how readily that unit can be implemented.

Test the book with open interest

Relative contract liquidity equals that contracts-to-trade count times total open interest times a volume factor. The product is a cross-market ranking of how readily an entire listed complex can be bought or sold, built from the equal-dollar unit, open interest, and the volume factor.

Open interest analysis uses outstanding contracts as the capacity term in that liquidity product so a wide historical range cannot disguise a book too small to absorb the implied size.

The volume factor is the greater of 1 and the exponential of the natural log of volume divided by the natural log of 5000, minus 2. It is a multiplier floored at one that reduces the liquidity product when volume is thin relative to a 5000-contract logarithmic benchmark.

A liquidity filter keeps only listed contracts whose activity, book size, and implementation cost can support an executable order over the life of that order.

Activity marks on the 2018 listing

Relative activity is marked on a comparative scale. More marks indicate more trading, and one mark or none indicates a thin book treated as less suitable for speculative use.

On the 2018 listing, equity-index and Treasury-note futures occupied the highest relative-liquidity ranks, while several agricultural, metal, and currency contracts sat at a single mark.

Effective percent margin

Effective percent margin equals posted margin dollars divided by the contract's three-year dollar price range, then multiplied by 100. It expresses posted margin as a percentage of the same three-year dollar range used to size the equal-dollar unit.

Equity turnover as a contrast

Equity trading liquidity is framed as period volume divided by shares outstanding, a turnover rate used as a proxy for how easily a stock can be traded.

TradersWeek editorial note: that turnover rate is a stock-market contrast. It is not the futures product of equal-dollar unit, open interest, and volume factor.

Editorial reading

TradersWeek editorial reading: a listed market clears this exam only when its book can carry the equal-dollar unit implied by its own three-year range. Open interest and the volume factor decide whether that size is bookable. The liquidity filter is the gate. Futures contract selection comes after.

The same three-year dollar range that sizes the equal-dollar unit is the denominator for effective percent margin, so implementation size and posted margin stay on one historical unit. Highest ranks for equity-index and Treasury-note futures on the 2018 listing record books that cleared that test more readily than contracts left at a single mark.
