Managing Orders

Take full control of your PrediX Limit Orders. Easily view statuses, execute batch cancellations, track partial fills, and manage your portfolio with automated notifications.

After placing a limit order, you can monitor it, cancel it, or wait for it to fill. PrediX gives you full control over your resting orders - single cancel, batch cancel, and automatic cleanup when markets resolve.

Viewing Open Orders

Navigate to Portfolio → Orders to view all your active orders across every market. Each row shows:

You can also view orders for a specific market on the market detail page, under the Orderbook tab → My Orders.

Cancelling Orders

How to Cancel a Single Order

1. Step 1: Locate Your Order

   • Navigate to your Portfolio and select the Orders tab.
   • Alternatively, go to the specific market’s detail page and find the My Orders tab.

2. Step 2: Initiate Cancellation

   • Find the specific order you wish to close.
   • Click the Cancel button located next to the order details.

3. Step 3: Confirm in Wallet

   • A prompt will appear in your wallet (e.g., Biometric scan for Passkeys or a pop-up for MetaMask).
   • Confirm the transaction to authorize the cancellation.

4. Step 4: Funds Released

   • Once the transaction is processed, your locked USDC or tokens are immediately returned to your wallet balance within the same transaction.

Note

No protocol fee on cancel. Gas is paid by the user; paymaster sponsorship applies if you qualify (both Passkey and EOA wallets eligible).

Cancel Multiple Orders

Select multiple orders with checkboxes, then click Cancel Selected:

Wallet Type	Behavior
Passkey + Smart Account	All cancels bundled into 1 UserOp - single confirmation, single gas (or sponsored)
Web3 Wallet (EOA)	One transaction per order - N confirmations

---

Cancel All Orders

Click Cancel All at the top of the Orders tab to cancel every open order across every market in one click.

Wallet Type	Behavior
Passkey + Smart Account	1 UserOp bundles all cancels atomically
Web3 Wallet (EOA)	Sequential transactions (one per order)

Caution

Cancel All is irreversible. Once confirmed, all your resting limit orders are gone. If you change your mind, you’ll need to re-place each order manually.

Programmatic Cancel (API)

For bots and automated strategies, the same cancel functions are available via API:

• Cancel a single order
• Cancel orders in batch
• Cancel all orders in a market

---

Editing Orders

PrediX does not support direct order editing. To change an order’s price or size, you must:

1. Cancel the existing order
2. Place a new order with the updated parameters

For bots that frequently update quotes, the API supports cancelAndReplace - a single atomic operation that cancels and re-places in one transaction. See API → Replace Order.

---

Partial Fills

A limit order can be filled incrementally as different takers hit it:

BUY YES @ $0.45, 100 USDC
  → taker 1 fills 40 USDC at $0.45
  → taker 2 fills 30 USDC at $0.45
  → 30 USDC remains on the book
  → Status: PARTIAL

You have two options for the remainder:

Option	When
Wait	Let the rest fill at the same price
Cancel	Take what’s filled, get the remaining 30 USDC back

Filled portions are immediately yours - you don’t need to wait for the order to be 100% filled before holding the shares.

---

Automatic Cancellation

Orders are automatically cancelled in two scenarios - you don’t need to do anything:

Scenario	What happens
Market reaches endTime	All open orders for that market cancel; locked funds return
Market enters refund mode	All open orders cancel; locked funds return

You’ll receive a notification when this happens. Check Portfolio → History to see the OrderCancelled event with reason MARKET_ENDED or REFUND_MODE.

Note

You’ll be warned before endTime. The app sends a notification 24h, 1h, and 5 minutes before market endTime if you still have open orders. Decide whether to cancel manually or let them auto-cancel.

---

Order Status

Status	Meaning
OPEN	Resting on the orderbook, no fills yet
PARTIAL	Filled in part, remainder still resting
PENDING	Match in progress (block not yet confirmed)
FILLED	Fully matched - appears in History, not in Open Orders
CANCELLED	Cancelled by you or auto-cancel - funds returned

---

Order Limits

Parameter	Value
Max open orders per user	50 per market
Max total open orders	500 across all markets
Min order size	1 USDC (BUY) or 1 share (SELL)
Tick size	$0.01 (prices like 0.45, not 0.455)

If you hit these limits, you’ll need to cancel existing orders before placing new ones.

---

Notifications

The app notifies you when:

• An order fills (full or partial)
• An order is cancelled (manual, auto, or refund mode)
• An order is nearing endTime (24h / 1h / 5min warnings)
• An order is stale (more than 7 days old with no fills)

Toggle notification settings in Notifications & Alerts.
