Submitting a HIP-4 Order

The order entry UI is the same as Polymarket.

1. HIP-4 Markets can be access via Predict from the top navigation bar, Hyperliquid tab.

2. Pick an event and an outcome. Each event has a price-history chart and one or more outcomes (typically Yes/No, but Hyperliquid sometimes uses labels like A/B or custom names defined by the market creator).

3. Choose an order type. The supported types are the same as Polymarket:

   • Market executes immediately against the best available prices.

   • Limit sets the price (in cents, where 1 cent = 1% probability) you're willing to pay or receive.

   • VWAP spreads the order over time at volume-weighted average pricing.

   • TWAP and Aggressive Maker are also available.

4. Enter trade size, eitehr by dollar amount or by number of shares. Your available balance shows next to the field and turns red if you exceed it.

Hyperliquid enforces a 10 USDH minimum per order placement on HIP-4. Your order size needs to be large enough that every placement clears 10 USDH — not just the total margin. Undersized trades will result in rejected placements or an idle bot.
