Prices and ticks

Prices are expressed in ticks, the smallest price increment for a market. Each market defines its tick_size in quote asset native units. See Markets.

To convert a dollar price to ticks:

ticks = (price_in_dollars * quote_native_units) / tick_size

For example, BTC-USDC has a tick_size of 1,000,000 (i.e. $1.00 per tick). A limit order at $50,000:

ticks = (50,000 * 1,000,000) / 1,000,000 = 50,000

Quantities and step sizes

Quantities are in base asset native units and must be multiples of the market’s qty_step_size.

Asset	Native unit	Units per 1 token
BTC	satoshi	100,000,000
ETH	gwei	1,000,000,000
SOL	lamport	1,000,000,000
USDC	micro-USDC	1,000,000

For example, to place an order for 0.001 BTC:

qty = 0.001 * 100,000,000 = 100,000

Both ticks and qty are transmitted as integers (or integer strings) in JSON. Large numeric fields accept either format: "qty": "100000" or "qty": 100000.
