Trading strategies on thin futures contracts
Strong measured edges on thin contracts need a capacity curve beside them, because a standard gate stack never looks at volume.

The hypothesis, as pre-registered
Less-traded contracts are less efficiently priced, so the same screening process should find stronger edges there.
What the test found
It does find stronger edges there — and they are untradeable. The median thirty-minute regular-session bar on the thinnest of these contracts carries a volume of roughly three contracts.
A standard backtest fills at the bar's price regardless of whether the size existed. No gate in a conventional screening stack looks at volume at all, so a thin market will pass every statistical test and fail the only test that matters, which is whether you can get in and out.
The correct control is a capacity curve: charge square-root market impact against measured depth and re-run. Edges of this kind disappear at a size barely above one contract.
The lesson generalises. Any screen that ranks markets by measured edge without a liquidity floor will rank the thinnest markets first.
What would make this work
The edge would have to survive a market-impact charge at a participation rate the contract can actually support, at a size worth trading.
Every insight ends with this line: the exact condition that would turn the finding into a tradeable edge. That is what makes each entry a next experiment rather than a full stop.
