⚖️ Long/Short Ratio & Open Interest

Chart Binance futures long/short ratios, top-trader positioning, open interest and taker flow against price, read as new longs or short covering.

–

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.

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.

Reading the screen, section by section

Coin, period and open-interest unit

The dropdown lists the top 100 Binance crypto perpetuals by 24-hour volume (stablecoins and stock or commodity perpetuals are left out). The period buttons (5m, 15m, 1H, 4H, 1D) set both the candle length and the spacing of the long/short and open-interest statistics. Binance publishes these statistics for the last 30 days only, so up to 200 points are loaded, about 180 on 4H and about 30 on 1D; the 'N points · ~D' note on the right is the span actually covered. 5m covers about 17 hours, 15m about two days and 1H about eight days. The unit buttons only switch the chart between USDT value and coin quantity; the reading always uses coin quantity, because the USDT value rises with price even when positions do not change.

Price chart

The first pane is the Binance perpetual candle chart, and its legend shows the close and in-bar change of the bar under the cursor (or the latest bar). The chart set reloads every 30 seconds, so the rightmost, still-open bar changes shape every 30 seconds. All four panes share one time axis: dragging or zooming one moves the others, and a crosshair in one pane appears at the same time in the rest. Long/short ratios and open interest are snapshots taken when a bar closes, so the open bar has no value and the latest figure sits on the last closed bar. That is why the lower panes only catch up with a big move in the open bar after it closes and the statistic is published.

Open interest chart

The second pane draws open interest, the total of futures contracts not yet closed, as an area. Each value is the snapshot Binance records once per period, shown in USDT or in coins depending on the unit button. It rises when new positions open and falls when positions are closed or liquidated. Read it against the price pane: did open interest grow or shrink while price moved? A sharp drop in open interest on a big candle is the footprint of positions being unwound in bulk. A common mistake is to read a rise in the USDT chart as fresh entries; the value grows with price alone, so switch to coins to see real changes. Anything older than 30 days is blank.

Long/short ratio chart

The third pane has three lines. The two solid lines are the all-accounts ratio (accounts net long ÷ accounts net short, mostly retail) and the top-trader position ratio (long size ÷ short size among the top 20% of accounts by margin balance); the dashed line is the top-trader account ratio (the same top 20%, counted by accounts). The dotted horizontal line is 1.0: above it longs outnumber shorts, below it shorts do. A ratio r converts to a long share of r ÷ (1 + r), so 1.5 means 60% long. When watching live, the moment worth noticing is when the all-accounts line and the top-position line split to opposite sides of 1.0. These ratios measure crowding by headcount or size, not trading volume, and every long has a short on the other side, so the number of contracts is always equal on both sides.

Taker buy/sell chart

Each bar in the fourth pane is market-buy volume ÷ market-sell volume for that period. Bars rising above the 1.0 baseline had more market buying; bars below it had more market selling. Takers trade immediately instead of waiting in the order book, so this shows the direction of urgent orders coming in or getting out. Each value is stamped at the start of its period, so it lines up with the matching price candle. Watch whether bars above 1 keep coming while price rises, or whether price rises while the bars stay below 1. A single spike is often one or two large orders, so the 24-bar total in the right-hand panel is the steadier read.

Current positioning

The three bars at the top of the right-hand panel show the latest all-accounts, top-trader position and top-trader account ratios with their long and short shares, and the heading shows that snapshot's time (when its bar closed). The six tiles below give the current price (close of the open bar) with a KRW conversion, open interest in USDT and in coins, the change in open interest over the last 24 bars (in coins, with the USDT change beside it), price change between the same two moments, the last bar's taker ratio and the 24-bar total (buy and sell volumes summed separately, then divided), and the current funding rate with its next settlement time. 24 bars means two hours on 5m, a day on 1H and 24 days on 1D. The price updates every 30 seconds, but the two change tiles compare closed-bar snapshots and only move when a period ends.

Reading paragraph

The paragraph at the bottom of the panel is written by fixed rules. First it picks one of four cases from the signs of the 24-bar price change and open-interest change in coins: price up with OI up is new longs dominating, price up with OI down is short covering, price down with OI up is new shorts dominating, and price down with OI down is long liquidation. If price moved less than ±0.5% or open interest less than ±1%, it adds 'weak' and drops the confident explanation. It then notes when all accounts are at 1.05 or above while top positions are at 0.95 or below (or the reverse), meaning retail and whales sit on opposite sides; adds the 24-bar taker total; flags a ratio in the top or bottom 10% of loaded values (with at least 20 values); and notes when open interest is at the high or low of the loaded period. The four case names are common readings of each combination, not calls on what comes next.

Top 15 by volume table

The table compares the 15 crypto perpetuals with the highest 24-hour volume. Price and 24h change come from Binance's 24-hour ticker; the all-accounts and top-position ratios are the latest 5-minute snapshot; Open interest is in USDT; 'OI 24h' and the '24h reading' compare coin quantity now with 24 hours earlier from 25 hourly snapshots. The reading's price change is derived from open-interest value ÷ quantity at those two snapshots, so it compares exactly the same two moments. Funding is the current estimate. The table rescans every 60 seconds and cells update as each coin arrives while the progress bar fills; because the statistics pass through a 60-second cache, fresh values actually land every one to two minutes. Click a header to sort, or a row to load that coin into the charts above.

Keeping it open

With the page open, the charts and right-hand panel reload every 30 seconds and the table every 60 seconds. Long/short, open-interest and taker statistics are only produced when a period ends, though, so the latest value can be up to one period old; what changes within 30 seconds is mostly the open candle and funding. For live watching the 5m and 15m periods suit best, while the bigger picture is better checked a few times a day on 1H or longer. Switching tabs pauses refreshing, and it resumes immediately when you return. Scan in the order below, and keep a funding-rate ranking or live liquidation monitor in a nearby tab to see whether crowding spills into liquidations.

Table: find coins in the top 15 whose reading has changed
Crowding: have all accounts and top positions split apart?
Flow: 24-bar change in open interest and price
Orders: are taker bars staying on one side?

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 180 points and 1D about 30. 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.
