StreamCandle - Stream Live OHLCV Candles
Subscribe to sparse, live Hyperliquid OHLCV bucket snapshots for one coin and interval over the V3 gRPC API.
StreamCandle sends live snapshots of one epoch-aligned OHLCV bucket for a (coin, interval) pair. It is a live view, not the historical candle product.
Request and opening behavior
Both coin and interval are required. Supported intervals are 1s, 1m, 3m, 5m, 15m, 30m, 1h, 2h, 4h, 8h, 12h, and 1d.
If the gateway already tracks the bucket, its current state arrives immediately. A cold subscription waits for the next execution, so its first bucket can be partial. Buckets are sparse: no execution means no frame. A new open_time signals rollover, and the previous bucket's final frame is sent first.
Delivery and recovery
Frames with the same open_time supersede earlier frames. Subscriber lag is recoverable for an open bucket, although a dropped closing frame can only be inferred from a later open_time. FAILED_PRECONDITION means candle streaming is unavailable; ABORTED means the stream state reset. See the gRPC overview for shared errors.
