Dataset
FreeTrading Rules Reference
The change history of trading rules — per row: rule domain, rule key, effective date, end date, prior value, new value, market, and description; sourced from the TWSE.
Download without registration: sample data using one of the five no-key symbols (2330 TSMC) as the example.
What this data is
Each row is one change to one trading rule, carrying rule_domain / rule_key / effective_date / end_date / prior_value / new_value / market / description (rule domain, rule key, effective date, end date, prior value, new value, market, and description). Sourced from the TWSE, graded reference / master. 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
- Recover the rule parameters (e.g. price limit) in force on any date via effective_date.
- Track the history of tick, day-trading, and odd-lot rules.
- Give backtests a point-in-time-correct rule baseline.
Why it matters for stock analysis
Rule parameters change over time; applying today's rules to the past distorts backtests. This dataset serves rule history with effective/end dates, point-in-time safe.
