New Parameter: `metricType` for Futures Long/Short Ratio

March 31, 2026

The Futures Long/Short Ratio endpoint now supports an optional metricType parameter, giving you more granular control over which ratio metric is returned.

Value	Description
default	Long/short ratio across all accounts on the exchange. Available for all supported exchanges.
topTraderPositions	(Binance only) Dollar-weighted long/short ratio among the top 20% of traders by margin balance. Reflects where the largest capital is allocated.
topTraderAccounts	(Binance only) Account-count-based long/short ratio among the top 20% of traders. Each account is counted once regardless of position size, reflecting how many large traders are bullish vs bearish.

When metricType is omitted, the endpoint behaves as before and returns the default metric.

Note: topTraderPositions and topTraderAccounts are only supported for binance. Requests using these values with other exchanges will return a 200 OK with an empty data array.

Why does this matter?

Tracking sentiment across all accounts can be noisy. Retail traders make up the majority and often trade in the opposite direction of the market’s eventual move. By isolating top trader data, you can cut through that noise and focus on the positioning of the participants most likely to have an informed edge. Use topTraderPositions to see where the largest capital is actually deployed, or topTraderAccounts to gauge directional consensus among experienced traders independent of position size.
