What is Long/short ratio?
The long/short ratio is the number of accounts on an exchange holding a long position in a contract divided by the number holding a short. A reading of 2.0 means two long accounts for every short one. It counts people, not money, and on most crypto perpetuals it sits above 1 nearly all the time.
Perpetual futures exchanges publish the ratio every few minutes, usually in three versions: every account by headcount, the largest accounts by headcount, and the largest accounts weighted by position size. The first two move almost identically — the 'top trader' headcount line is the crowd counted a second time — while the position-weighted line is a genuinely different series that measures where the money leans rather than where the people do.
Because it counts heads and most accounts are small buyers, the ratio's resting state is above 1: over six years bitcoin's crowd had more longs than shorts on about four days in five, and solana's on nearly every day. So a reading above 1 is not bullish on its own, and the same number means different things on different contracts. The ratio is only readable against its own recent history. It also swings mechanically against each big candle — rising after a sharp fall as shorts take profit and dip-buyers arrive, falling after a sharp rise — so its day-to-day change mostly repeats the price move rather than adding to it.
For example
Bitcoin's crowd ratio reads 1.50 and solana's reads 2.50. Both are ordinary: 1.5 is close to bitcoin's median and 2.5 is close to solana's. The reading that has historically carried information is the unusually LOW one for a given contract — the crowd less long than at almost any point in the past year — which has tended to precede a better-than-average month.

It is the most-quoted sentiment number in crypto and the most misread. Knowing that it counts accounts rather than dollars, that its baseline is well above 1, and that the top-trader headcount version adds nothing over the crowd version turns it from a reflex ('everyone is long, fade it') into a gauge you can actually read alongside funding and open interest.
⚠ Following the 'top traders'
The top-trader account ratio tracks the all-account ratio almost one for one, so it tells you nothing the crowd line does not. The position-weighted version is different — but its extremes have shown no consistent direction in six years of data. 'Follow the big accounts' is not a strategy the ratio supports.
