🪃Order Life Cycle

Every state an order can be in, and how transitions happen

Track your orders' states in the Order History tab of the Portfolio page. An order passes through one or more of seven states:

State	Applies to	Meaning
Open	Limit	Resting on the book, waiting for a match
Partially Filled	Both	Part executed; remainder rests (limit priced inside the circuit-breaker range) or is terminated (market, or limit priced beyond the range)
Filled (final)	Both	Fully executed — now a position
Killed (final)	Market / crossing limit	Could not fully execute due to insufficient liquidity
Blocked (final)	Market / crossing limit	Execution stopped by the Circuit Breaker price range
Cancelled (final)	Limit	Cancelled by you before full execution
Expired (final)	Limit	Still unfilled when the market reached maturity; allocated funds return to your deposit balance

Combined states such as Partially Filled & Killed or Partially Filled & Cancelled record that part of an order executed before the remainder terminated.

Order status transitions

Behind the scenes: a filled order becomes a position (Future Value), and an auto-rolled position is tracked in Genesis Value terms

Scenario walkthrough

Consider this order book (last price 90; circuit-breaker range for the next block: 88–92, simplified for illustration):

Price | Amount
---------------
  93  |  0
  92  |  0     <- upper limit (this block)
  91  |  10
  90  -- last price
  89  |  5
  88  |  0     <- lower limit (this block)
  87  |  10

Market orders

• Buy 10 at market → fills 10 at 91 → Filled

• Buy 20 at market → fills 10 at 91; no more liquidity within the limit → Partially Filled & Killed

• Sell 10 at market → fills 5 at 89; the rest would execute below the lower limit → Partially Filled & Blocked

Limit orders (overlapping — price crosses existing orders)

• Buy 10 at 91 → Filled immediately

• Buy 15 at 92 (at the upper limit) → fills 10 at 91; the remaining 5 rest on the book at 92 → Partially Filled, then later Filled / Cancelled / Expired

• Buy 15 at 93 (beyond the upper limit) → fills 10 at 91; the remaining 5 would execute beyond the circuit-breaker limit, so they are blocked and the allocated funds return to your deposit balance → Partially Filled & Blocked

Limit orders (non-overlapping)

• Buy 10 at 89 → Open, waiting for a counterparty

• Market matures with the order unfilled → Expired, funds returned

Common questions

What's the difference between Killed and Blocked?

Killed = not enough liquidity to fill the remainder. Blocked = the remainder would have executed outside the circuit breaker's allowed price range. Both are final states for the taker side of an execution — market orders, or limit orders that cross the book; the filled portion (if any) remains as a position.

What happens to open orders when the market matures?

They expire automatically and the allocated funds return to your deposit balance. Filled portions become positions and are subject to Auto-Roll.

Can I modify an order?

No. Cancel the order and place a new one — this preserves fair price-time priority for everyone.
