Binance Perpetual OHLCV: Event Time vs Retrieval Time

Binance USD-M klines share the spot format, and the same live-bar trap. Mark, index and premium klines add placeholder fields with their own timing.

Short answer

USD-M futures klines return open time, OHLC, volume, close time, quote volume, trade count and taker-buy volumes. As with spot, the last kline is usually live. Mark-price, index-price and premium-index klines use the same layout with 'Ignore' slots. For event time, use open and close times; for freshness, record retrieval time and compare. When joining trade klines with mark or premium klines, join on open time.

Illustrative: a basis series joins trade and index klines on close time; because the live bar's close time is the scheduled end, not the last update, the join pairs values read at different moments.

Sources and methodology
