Contrarian trading - market activity
Fade extremes when price stretches from fair value; trends can keep stretching longer than your margin account.
Overview
Bells and whistles can be added to the above “basic” mean-reversion strategy by incorporating volume and open interest filters. Let Vi be the total volume for the futures labeled by i over the last week (i.e., the sum of daily volumes over the last week), and V′ i be the total volume over the prior week.
Contrarian trading - market activity sits in the Futures chapter of the systematic catalog. On QUSXFI we treat it as a testable hypothesis: specify entries, exits, sizing, and costs—then ask whether edge survives out-of-sample scrutiny.
Discretionary traders often arrive at similar ideas intuitively; the quantitative version forces you to write the rule before you see the next bar. That discipline is what makes results reproducible—or exposes them as luck.
