`compare_funding_rates_across_venues`

Compare funding rates across exchanges · read-only, idempotent, no account needed · scopes: read

Current perpetual futures funding rate for one coin on every exchange TradeHub supports, per interval and annualised, with the age of each reading. Use when choosing where to hold a long or a short, or to check a funding spread. Not a forecast: rates change every interval. Input: symbol (base coin). Rates are fractions; positive means longs pay shorts. Sorted by annualised rate, highest first; TradeHub takes no rebates from any exchange. Next: get_perp_contract_rules(venue, symbol) or size_position_by_risk.
