Binance Spot OHLCV: Event Time vs Retrieval Time
Binance spot klines carry an open time and a close time. The last kline in a response is usually still open — its close time is in the future.
Short answer
Binance spot klines are 12-field arrays starting with open time and including close time; a kline is identified by its open time, and a timeZone parameter can shift interval boundaries. The most recent kline in a response is typically the live, unfinished bar: its close time is later than your retrieval time and its values will change. Record retrieval time, drop or flag klines whose close time is after it, and fix the timeZone setting.
Which times the data carries
| Time | Present? | Meaning |
|---|---|---|
| Open time | Yes | Kline identity |
| Close time | Yes | End of interval |
| Retrieval time | No | Record it |
| timeZone param | Request | Shifts boundaries |

Example
Illustrative: a daily dataset stored at 13:42 includes today's kline with only 13 hours of data; treated as complete, it shows an artificially small range.

Interval boundaries.
Sources and methodology
Field definitions come from DEX Screener's API reference and CoinGecko's onchain API documentation, read 17 October 2026. Where a schema doesn't document a timestamp, this guide says so and recommends recording retrieval time yourself.
