Dataset
ProMargin System Statistics
Market-wide margin and short-sale system statistics — per row: total margin balance, total short balance, short-to-margin ratio, margin net flow, and maintenance ratio; sourced from the TWSE.
What this data is
Each row is one trading day of system statistics, carrying margin_purchase_balance_total / short_sale_balance_total / short_to_margin_balance_ratio / margin_net_flow / maintenance_ratio (total margin balance, total short balance, short-to-margin ratio, margin net flow, and maintenance ratio). Sourced from the TWSE, graded derived (computed from official data). Keyed on the data as-of date and point-in-time safe; The backend /v2/datasets meta exposes only grade / tier / point-in-time and no coverage window, so none is stated here.
Use cases
- Watch market leverage and margin-call risk via short-to-margin and maintenance ratios.
- Track margin net flow as a retail-leverage sentiment read.
- Use as the systemic-risk monitor for margin trading.
Why it matters for stock analysis
Margin/short system stats span several daily reports; this dataset consolidates leverage metrics (incl. maintenance ratio) one row per day, point-in-time safe.
