Data And Licensing
The source market inputs are not redistributable. This repository contains no raw data, private SQLite database, cache, token, or licensed Orient report. Equivalent data must be obtained lawfully by the user. The supplementary Chinese PDF is an author-produced replication report, not the original source publication.
Replication Scope
The daily main/sub-main selection is a volume-based approximation. Spot and warehouse-receipt coverage are limited by available inputs. Some member-position, stock-inventory, and other components needed by the intended combinations are unavailable; the public multi-factor summary records those gaps in its missing factors field.
Trading Realism
Headline results are gross of commissions, bid-ask spread, market impact, roll execution, margin financing, exchange price limits, position limits, liquidity capacity, and operational constraints. Contract mapping and rebalance execution are simplified. Results are therefore research diagnostics, not a deployable strategy estimate.
Inference
The published period is historical and the results are primarily in-sample replication evidence. Multiple factor variants, parameter grids, and data definitions create selection risk. A production study should use frozen specifications, rolling or holdout validation, realistic execution modelling, and capacity analysis.
