Using Futures Position Data and Turnover Ratios to Guide Trading

Summary

This report examines futures open interest and broker position data as clues to capital flows and possible price behavior, using rebar futures as its main example. It argues that volume or open interest alone may be weak predictors, while the turnover-to-open-interest ratio can help identify active markets and contextualize position changes. The analysis also applies the Bessembinder–Seguin approach to volatility and momentum models, finding that large institution net-position changes in high-turnover conditions are associated with higher volatility and positive price feedback.

A rolling-optimization strategy based on position information is evaluated on rebar futures. The report gives cumulative and annualized returns, drawdown, win rate, and Calmar ratio, and compares versions with transaction costs and stop-loss rules. It reports better drawdown control with a suitable stop and identifies ranges of institution counts, entry thresholds, and stop levels that performed relatively well. These are historical results for one contract strategy; the supplied text omits a turnover threshold in one finding and provides no full methodology or evidence of out-of-sample robustness.

Key ideas

• Open interest and broker positions can provide clues about capital flows in futures markets.
• The turnover-to-open-interest ratio may help interpret the significance of position changes.
• The report links high turnover and rising institutional net positions with volatility and momentum effects.
• A rolling-optimized rebar strategy uses position changes for entries and stop-loss rules for risk control.
• The reported performance is specific to the tested rebar strategy and does not establish robustness elsewhere.
