# List Ownership Signals

`GET /v1/ownership/signals`

Get market-wide ownership signals.

Returns detected signals ordered by date (newest first).
By default excludes trivial signals (tier 3: new_position, exit_below_5pct).
Pass include_trivial=true or filter by specific signal_type to see all.

## Query parameters

- `signal_type` string, nullable — Filter: accumulation_streak, large_step_up, large_step_down, exit_below_5pct, activist_escalation, new_position, pace_acceleration, purpose_drift, coordinated_accumulation, systematic_exit
- `filer_code` string, nullable — Filter by filer EDINET code (e.g. 'E03606' for SBI Holdings)
- `include_trivial` boolean — Include tier 3 (trivial) signals like new_position and exit_below_5pct. Default returns only tier 1 (actionable) and tier 2 (informational).
- `date_from` string, date, nullable — Filter: detected_date on or after
- `date_to` string, date, nullable — Filter: detected_date on or before
- `limit` integer — Results per page
- `offset` integer — Results to skip (ignored when cursor is set)
- `cursor` string, nullable — Opaque cursor for keyset pagination
