Parameters

​
Request body

  • type (string, required) — The request type. Must be "maxMarketOrderNtls" to retrieve maximum market order limits.

​
Response

The response is an array of objects containing market order limits for each asset:

​
Market order limit fields

  • coin (string) — Asset symbol (e.g., “BTC”, “ETH”, “SOL”, “AVAX”)
  • maxNtl (string) — Maximum notional value allowed for market orders in USD
  • maxSz (string, optional) — Maximum size allowed for market orders in asset units

​
Understanding market order limits

Notional value limits:
  • Expressed in USD regardless of the asset being traded
  • Prevents single orders from causing excessive market impact
  • Varies by asset based on liquidity and volatility characteristics
Size limits:
  • Expressed in native asset units (e.g., BTC, ETH)
  • May not be present for all assets
  • Provides alternative sizing constraint alongside notional limits
Risk management:
  • Limits protect both traders and the exchange from extreme market movements
  • Larger, more liquid assets typically have higher limits
  • Limits may be adjusted dynamically based on market conditions
