Market making on SX Bet is capital-efficient by design: your balance is not divided across the markets you quote. The same funds can back liquidity everywhere at once.

​
How maker exposure is limited

When you post resting (GTC) liquidity, the exchange checks:
That check runs per market and outcome. Orders on different markets — or on the opposite outcome of the same market — do not draw down each other’s budget. Every market:outcome is allowed up to your full balance. An order that would push a single market:outcome over your balance is rejected.

​
Example

With a $1000 balance you can post up to $1000 of liquidity on any number of markets at the same time:
  • $1000 on market A, outcome 1
  • $1000 on market B, outcome 1
  • $1000 on market C, outcome 2
Each is measured against the full $1000 — there is no shared pool being divided up, so all three rest at once. What you cannot do is exceed $1000 on a single market:outcome: if you already have $600 resting on market A outcome 1, a further order there is capped at $400. Anything larger is rejected.

​
Capital is not locked until a match

Posting an order does not move any funds into escrow, regardless of its timeInForce. Capital is locked only when an order matches — the moment a taker fills your resting quote, or your own order crosses the book. Until then, resting quotes across many markets cost you nothing to keep on the book.

​
Scale-down when your exposure exceeds your balance

When a match locks capital and drops your available balance below what your resting orders still require, the exchange automatically cancels resting orders to bring you back within budget. Cancellation is worst-odds-first, across all your markets:
  1. The orders furthest from 50% implied odds — the least likely to ever fill — are cancelled first.
  2. Larger orders break ties, so the deficit is covered in as few cancellations as possible.
  3. Cancellation stops as soon as every market:outcome is back within your balance. Orders already within budget are left untouched.
Orders removed this way become INACTIVE with inactiveReason: INSUFFICIENT_BALANCE. Watch your account:orders_v3 stream to react — see Order lifecycle for the full list of inactive reasons.

​
Takers work differently

Non-resting (IOC / FOK) orders lock real capital the instant they fill. Unlike maker exposure, taker size is measured globally — the sum of your in-flight taker orders across every market must fit within the one balance, because each fill draws real funds immediately. A taker order that would exceed your balance is rejected with the same Insufficient available balance for this order size error.
