Fired when a trade occurs at a near-certain-outcome price. At least one of min_probability or max_probability is required. Use min_probability (e.g. 0.95) to trigger when YES is near-certain; use max_probability (e.g. 0.05) for NO near-certain. Optional filters: position_outcome_indices — restrict by outcome index (0 = Yes/Up, 1 = No); condition_ids — restrict to specific markets; position_ids — restrict to specific outcome tokens; outcomes — restrict by outcome name (e.g. "Yes", "No"); event_slugs — restrict to specific events.
