  • Wire-equal to POST api.hyperliquid.xyz/info with {"type": "maxMarketOrderNtls"}.
  • Each entry is a [leverage, maxNotionalUsd] tuple; the notional is a decimal string.
  • This is a global, non-user-keyed type. Buckets are ordered from highest leverage to lowest.
Returns the maximum market-order notional permitted at each leverage bucket. Each element is a [maxLeverage, maxNotional] tuple: a position running at up to maxLeverage may place a single market order of at most maxNotional USD. The cap tightens as leverage rises, bounding slippage on aggressive market orders.

Field descriptions

The notional value in each tuple is returned as a decimal string, preserving upstream precision. Do not parse it as a float - keep it as a string or use a fixed-precision decimal type.
