AMM orders

AMM orders execute instantly at the calculated price.

​
CLOB orders

CLOB orders support different execution strategies through time-in-force options.

​
Time-in-force options

  • GTC (Good Till Cancel) — stays on the book until filled or manually cancelled. Default for limit orders.
  • FAK (Fill and Kill) — execute as much as possible immediately, cancel any unfilled portion.
  • FOK (Fill or Kill) — execute entirely or cancel completely. No partial fills.
  • GTD (Good Till Date) — remains active until a specified expiry time.

​
Order types

  • Limit orders — specify the max price you’ll pay (buy) or min price you’ll accept (sell). Execute at your price or better.
  • Market orders — execute immediately at the best available price.

​
Order statuses

  1. pending — order received and being validated.
  2. open — active on the book, waiting for matches.
  3. partial_filled — some shares executed, remainder still on book (GTC/GTD only).
  4. filled — completely executed.
  5. cancelled — cancelled by user or system.
  6. rejected — failed validation.
  7. expired — GTD order reached expiry time without filling.

​
Amending an open order

CLOB orders in open or partial_filled status can have their price, their size, or both mutated in place via batch amend. The order keeps its identity (orderId stays the same) and its current filledSize — the new size is the new TOTAL, so the new remaining becomes newSize − filledSize.
  • Independently optional fields — supply newPrice only, newSize only, or both. The omitted field keeps its current value. Items with neither field are rejected with BAD_REQUEST.
  • Time priority — preserved when the new (price, size) is unchanged or shrunk at the same price level. A price move (up or down) puts the order at the new tail of the new level, identical to a cancel-and-replace.
  • Funding — BID amends that grow the lock check wallet balance; ASK amends that grow the lock check the user’s free share balance. Either can be rejected per-item with INSUFFICIENT_BALANCE or INSUFFICIENT_SHARES.
  • Self-trade prevention — fixed server policy: any same-user resting crosser at the new price is auto-cancelled (CANCEL_OLDEST). The order’s resting stpMode set at placement governs matching, not amend. Crossers being amended in the same batch are skipped (no self-cancel). If you want an amend to fail rather than cancel a crosser, cancel + re-place instead.
  • Terminal orders — amend is rejected with NOT_FOUND once the order reaches filled, cancelled, expired, or rejected.
  • AMM orders — cannot be amended; cancel and re-place to change price/size.
