# Supported Ticket Sizes

> The largest firm quote available right now in each direction, per pair, and the limits that apply.

There is no fixed trade size. The size a firm quote covers right now is in every answer, and this table reads
it from `GET /levels` once a minute.

\<table><thead><tr><th>Pair</th>
              
                  \<th>You buy the coin
largest firm quote now</th>
                  \<th>You sell the coin
largest firm quote now</th></tr></thead>
          \<tbody /></table>

## How sizes work- **The largest firm quote now** is `maxFirmSize` on `GET /levels` (per direction) and on `GET /quote` (at the
  rate you were just quoted), in USDC and in the coin. A request above it answers `400 over-size` with the
  maximum in the detail; below the minimum, `400 amount-too-small` with the minimum.
- A quote at or below the size shown fills at exactly the quoted amounts or reverts: no slippage, no partial
  fill.
- The size is bounded by the maker's wallet balance for the coin it pays, its allowance to the order
  protocol, the largest trade its book allows and the quotes it is holding for other takers. It moves as fills
  happen and as makers rebalance, so read it at runtime rather than copying it.
- A dash with a reason means the direction is not quoted at this moment: *maker funding* (the maker's
  balance or allowance cannot cover a trade), *no midmarket rate*, *paused*.## Venue limits on stagingThe staging gateway also caps trades for testing: a maximum per trade, per wallet per day and across all
wallets per day. The live values are under the table and in `GET /config` → `limits`.## Need more?For a size that must always be available, or a pair not listed, write to
