Crypto Taker-Buy Volume: Null vs Zero - Handle Missing Fields Correctly

Binance publishes taker-buy volume inside every kline and as a separate ratio series. A zero taker-buy volume and a missing record are different signals.

Short answer

Each Binance kline includes taker-buy base and quote volume; taker-sell volume is total volume minus taker-buy. The separate takerlongshortRatio endpoint returns buySellRatio, buyVol and sellVol for the latest 30 days. Taker-buy "0" in a bar with positive volume means every aggressive trade was a sell — a real observation. A ratio record that is missing is a gap. And a buySellRatio computed with sellVol 0 is undefined, not infinite: guard the division.

Illustrative: a bar with 120 BTC volume and 0 taker-buy volume is a one-sided sell bar, not missing data. A ratio of 0 would be correct; a ratio of null would hide the signal.

Questions readers ask

Is taker-buy volume zero ever valid?

Yes; all aggressive trades were sells.

How do I get taker-sell volume?

Total volume minus taker-buy volume.

What if sellVol is 0?

The ratio is undefined; handle it explicitly.

Sources and methodology

Field definitions come from DEX Screener's API reference, CoinGecko's onchain API documentation and Binance's Spot API documentation, read 17 October 2026. Where a schema was not visible in the documentation, this guide says so and describes defensive handling rather than asserting field behaviour.
