Fired when a position’s price moves significantly. Use min_price_change_pct to set the minimum move (e.g. 10 for 10%). Use window_secs to observe moves within a specific time window. Use spike_direction ("up" | "down" | "both") — defaults to "up" when not provided. Filter by position_ids or outcomes to narrow scope.
