Binance publishes long/short and open-interest statistics for the last 30 days only. Each value is the snapshot taken when the bar closes and is drawn on that bar. The taker ratio is market-buy volume ÷ market-sell volume within each bar.

L/S = longs ÷ shorts (above 1 means more longs).

What this tool does

See which side of the futures market positions are leaning toward, and whether new money is coming in or existing positions are leaving, on one screen. The tool overlays Binance USDⓈ-M perpetual long/short ratios (all accounts and top traders), open interest (OI) and the taker buy/sell ratio on the same time axis as price, then reads the price and OI move as new longs, short covering, new shorts or long liquidation.

How it is calculated

Binance's public futures statistics are fetched per period (5m, 15m, 1H, 4H, 1D), up to 200 points; Binance publishes only the last 30 days. Long share = ratio ÷ (1 + ratio); short share = 100% − long share. The all-accounts ratio is accounts holding longs ÷ accounts holding shorts; top traders are the top 20% of accounts by margin balance ('positions' compares position size, 'accounts' compares account count). OI and long/short values are snapshots taken when a bar closes, so they are drawn on that bar. Changes use the last 24 bars: OI change = latest coin quantity ÷ quantity 24 bars earlier − 1, and price change compares the closes at the same two times. OI in USDT grows with price even when positions are unchanged, so the reading uses coin quantity. Price up & OI up = new longs dominate, price up & OI down = short covering, price down & OI up = new shorts dominate, price down & OI down = long liquidation; if price moved less than ±0.5% or OI less than ±1% the signal is marked weak. When the all-accounts ratio is 1.05 or more while the top-trader position ratio is 0.95 or less (or the reverse), the tool notes that retail and whales are on opposite sides. Taker ratio = market-buy volume ÷ market-sell volume; the 24-bar total sums each volume before dividing. A long/short ratio in the top or bottom 10% of the loaded values is flagged as unusually one-sided. KRW figures are the USDT price times Bithumb's USDT/KRW rate, for reference.

Pick a coin and a period. 5m and 15m cover the last few hours to two days, 1H about a week, 4H and 1D the last month.

In 'Current positioning' compare the long/short split of all accounts and top traders, then read how price and OI moved over the last 24 bars.

Hover or tap a chart: all four panes show price, OI, long/short ratios and the taker ratio for the same bar.

Things to know

When the long/short ratio is heavily one-sided, many traders expect a sharp move the other way to trigger a chain of liquidations. The imbalance alone does not tell you the next direction.

The all-accounts ratio counts people; the top-trader position ratio weighs money. When they disagree, neither side is automatically right, so read them alongside price.

Rising OI with a strongly positive funding rate is read as leverage building on the long side; rising OI with negative funding, as leverage building on the short side.

Frequently asked questions

What does a long/short ratio above 1 mean?

More of the counted side holds longs than shorts. A ratio of 1.5 means 60% long and 40% short (long share = ratio ÷ (1 + ratio)). Every futures long has a short on the other side, so total contracts always match; this ratio measures the lean by account count or by top traders' position size.

How do the all-accounts and top-trader ratios differ?

The all-accounts ratio compares the number of accounts holding longs with those holding shorts, so it mostly reflects retail sentiment, where small accounts are numerous. Top traders are the top 20% of accounts by margin balance; their 'positions' ratio compares long and short position size, and their 'accounts' ratio compares how many of them are long or short.

What does rising or falling open interest mean?

Open interest is the total of contracts not yet closed. It rises when a new long and a new short open a contract together and falls when existing positions are closed or liquidated. Read with price, it suggests whether a move was driven by new positions or by existing ones closing. The reading uses coin quantity so that price changes do not distort it.

Why only 30 days, and how often does it update?

Binance publishes these statistics for the last 30 days only, so 4H shows about 186 points and 1D about 31. Charts refresh every 30 seconds and the table every 60 seconds. The statistics gain one new value each time the chosen period ends (every 5 minutes on 5m, every hour on 1H), so the latest value can be up to one period old. Updates pause while the tab is hidden and resume as soon as you return.

How are the table's 24h reading and funding calculated?

The last 25 hourly snapshots compare OI (coin quantity) and price (OI value ÷ quantity) now and 24 hours earlier, giving one of the four readings, or 'Small change' when below the thresholds. Funding is the current funding rate Binance publishes: when positive longs pay shorts, when negative shorts pay longs.
