The long/short ratio is often read backwards. Lots of longs is not a reason to buy; it is a reason to check where those longs would be liquidated.

What the ratio shows

An exchange splits its clients into those with a net long and those with a net short position and publishes the proportion. A reading of 1.5 means there are one and a half times as many longs as shorts. The data comes from the exchanges themselves: Binance, OKX, Bybit and others.

Accounts and money are different numbers

The account ratio counts people: each account gets one vote, whether it holds a hundred dollars or ten million. The position ratio is weighted by money.

The interesting moments are when they disagree. If 70% of accounts are long but only 45% of the money is, many small traders are long while large money is short. Historically that kind of split has more often ended with a move against the crowd.

Top traders

Exchanges also publish how their largest clients are positioned, usually the top twenty percent by margin balance. The top trader page shows their positioning by accounts and by money and how far it differs from the whole market. Big accounts are not always right, but they tend to turn earlier than the crowd.

Why a crowded long is a risk

Every leveraged long is a future sell order if price goes down. When the crowd is heavily long, liquidation levels pile up below price, and a drop into them turns into a cascade. That is why many traders read extreme ratios as a warning, especially when funding is high at the same time.

Taker volume

The long/short page also shows taker buy and sell volume: whether market buyers or market sellers were the aggressors. Positioning tells you how the market is set up; taker volume tells you who is pushing right now.
