What the ratio counts
In futures, every open contract has one buyer and one seller, so total long contracts always equal total short contracts. The long/short ratio does not count contracts. It counts accounts (or positions) leaning one way or the other.
A ratio of 2.5 means that for every account net short, 2.5 accounts are net long. Because the contracts must balance, it also means the short side is held by fewer, larger accounts on average.
The versions you will see
Binance’s futures trading data, for example, publishes several related ratios:
- Long/short ratio (accounts): share of all accounts net long vs net short. This mostly reflects smaller traders.
- Top trader long/short ratio (accounts): the same, but only for the largest accounts by margin balance.
- Top trader long/short ratio (positions): weighted by position size, so it shows where the big money actually sits.
- Taker buy/sell volume: how much traded via aggressive market buys versus market sells. This is a flow measure, closer to CVD.
How traders read it
- Very high ratio: many small accounts are long. If price starts to fall, their stop-losses and liquidations can fuel a sharp drop, which is why many traders read extreme readings as contrarian.
- Very low ratio: the crowd is short, which can fuel a short squeeze if price turns up.
- Retail vs top traders disagreeing: when the all-accounts ratio is high but the top-trader positions ratio is falling, smaller accounts are buying what larger ones are selling.
The ratio describes positioning, not timing. A crowded market can stay crowded for days. Always wait for price to confirm.
Why funding and open interest are often clearer
The account ratio treats a $50 position and a $5 million position the same. Two numbers fix that:
- Funding rate is what the crowded side is actually paying to stay in. It is weighted by money, not head count. See funding rate explained.
- Open interest shows whether that crowd is still growing or already leaving. See how to read open interest.
CryptoScanX scans funding and open interest across 900+ perpetuals rather than the account ratio, because those two can be combined with price and volume into one condition:
Crowded longs still piling in
Longs paying well above the baseline while new positions keep opening. The kind of crowd that unwinds hard.

Frequently asked questions
Why is the long/short ratio not 1 if every long has a short?
Because it counts accounts or positions, not contracts. A ratio of 2 means twice as many accounts are long as short, so the short side is held by fewer, larger accounts.
Is a high long/short ratio bullish?
Not on its own. It shows that many accounts are long. Many traders read extreme readings as a contrarian warning, because crowded longs can be forced out quickly.
Where can I see the long/short ratio?
Exchanges publish it in their futures trading data. Binance, for example, shows the all-accounts ratio, top trader ratios and taker buy/sell volume per contract.
