Chronological before/after events after a stable forward-publication cursor. By default returns only stance, target-size and actionable risk changes; set material_only=false to include mark and score updates. Supports one-symbol filtering and pagination. Requires an active subscription. Completed end-of-day data, not real-time or investment advice.
