Field notes
The homepage separates research articles, a database, a forum, a shop, and a free-to-play market simulation. Its studies specify date windows, sample counts, and calculation methods—for example, one gold/silver ratio series spans 3,532 trading days, while an A-share liquidity study draws on 5,579 active stocks. The operator says datasets are checked weekly; an in-progress item describes standardizing 46 million market rows into seven fields with documentation and recalculation scripts.
