Asset Price Window Update

Event: asset_price_window_update
Cost: 0.1 credits per delivery

Fires twice per candle for a tracked asset — once when the window opens and once when it closes. The full payload schema is in the auto-generated Asset Price Window Update callback reference; this page documents the filters and matching behavior.

Related guide: Crypto Up/Down feed builds on these window open and close events to resolve Up/Down outcomes.

Notes

This event fires twice per candle — once when the window opens and once when it closes — so expect two deliveries per candle for each subscribed timeframe.
