A market mover is anything that just shifted hard: a probability that jumped, platform volume that accelerated, or a bucket of activity that spiked above its neighbors. Struct exposes three REST endpoints that cover these angles. markets.getPriceJumps finds sharp probability moves inside one market’s candle history, analytics.getChanges reports platform-wide percentage momentum, and analytics.getDeltas returns a per-bucket activity series you can render as a sparkline.

When to use this

  • Movers rails and “biggest moves today” widgets.
  • Alerting when a market’s implied probability swings past a threshold.
  • Dashboard headline numbers that show whether the platform is heating up or cooling down.
  • Sparklines that summarize recent platform activity at a glance.

Sharp price moves in a market

Use GET /v1/polymarket/market/price-jumps to detect candles where a market’s probability moved more than a threshold. Pass either condition_id or market_slug (one is required). The resolution is the candle size in minutes ("1", "5", "15", "30", "60", "240", default "15"), min_change_pct is the minimum move to report (default 10.0), and lookback is how many candles back to scan (default 1440, max 2500).
Each PriceJump row describes one move: from and to are the start and end timestamps (epoch seconds), price_before and price_after are the probabilities at each end, change_pct is the magnitude of the move, direction indicates whether it rose or fell, and volume and trades_count quantify how much trading drove it. The condition_id echoes the market so you can key the row in a list.

Platform-wide momentum

Use GET /v1/polymarket/analytics/changes for a single snapshot of how the whole platform is trending. The only parameter is timeframe ("1h", "24h", "7d", "30d", "1mo", "1y", default "24h").
The AnalyticsMetricPctChange response returns percentage changes for the headline platform metrics: volume_usd, unique_traders, txn_count, fees_usd, and related fields. Each value is the percentage move over the chosen timeframe, so positive numbers mean the platform is heating up. These map directly onto dashboard headline tiles.

Per-bucket activity sparkline

Use GET /v1/polymarket/analytics/deltas for a time series of platform activity you can plot as a sparkline. The resolution controls bucket size ("60", "240", "D", "W", "M", default "60"), and from, to, and count_back bound the window.
Each AnalyticsTimeBucketRow uses compact keys to keep the series small. They expand as follows: Plot v for an activity sparkline, or compare bv against sv to show whether buying or selling pressure dominated each bucket.

Push-based movers

The endpoints above are pull-based: you call them to find what already moved. For push-based movers that arrive as they happen, subscribe to the websocket spike alerts instead. The relevant alerts are price_spike for sharp probability moves, market_volume_spike and event_volume_spike for surges in trading volume, and position_volume_spike for individual positions. Use REST to seed a movers list, then keep it live with the spike alerts.
