# Market Parameters

> Min order size, lot size, tick size, and precision for all live Decibel markets

Each market has precision parameters that control valid order sizes and prices, returned from `GET /api/v1/markets`.
For conversion formulas, see [Formatting Prices and Sizes](/developer-hub/on-chain/overview/formatting-prices-sizes).

<Info>
  These values reflect mainnet at the time of writing. Always fetch live values from `GET /api/v1/markets` — parameters can change via governance.

## Order Size

`human = chain_value / 10^sz_decimals` — sizes must be a multiple of **Lot Size** and at least **Min Size**.

| Market   | sz\_decimals | Min Size              | Lot Size              |
| -------- | :----------: | --------------------- | --------------------- |
| APT/USD  |       5      | 1 APT `(100,000)`     | 0.1 APT `(10,000)`    |
| BNB/USD  |       7      | 0.002 BNB `(20,000)`  | 0.001 BNB `(10,000)`  |
| BTC/USD  |       8      | 0.00002 BTC `(2,000)` | 0.00001 BTC `(1,000)` |
| DOGE/USD |       4      | 20 DOGE `(200,000)`   | 1 DOGE `(10,000)`     |
| ETH/USD  |       8      | 0.0005 ETH `(50,000)` | 0.0001 ETH `(10,000)` |
| HYPE/USD |       6      | 0.05 HYPE `(50,000)`  | 0.01 HYPE `(10,000)`  |
| SOL/USD  |       7      | 0.02 SOL `(200,000)`  | 0.001 SOL `(10,000)`  |
| SUI/USD  |       5      | 1 SUI `(100,000)`     | 0.1 SUI `(10,000)`    |
| XRP/USD  |       5      | 1 XRP `(100,000)`     | 0.1 XRP `(10,000)`    |
| ZEC/USD  |       7      | 0.005 ZEC `(50,000)`  | 0.001 ZEC `(10,000)`  |

## Price

`human = chain_value / 10^6` (prices are in USDC, `px_decimals = 6`) — prices must be a multiple of **Tick Size**.

| Market   | Tick Size          |
| -------- | ------------------ |
| APT/USD  | \$0.0001 `(100)`   |
| BNB/USD  | \$0.01 `(10,000)`  |
| BTC/USD  | \$0.10 `(100,000)` |
| DOGE/USD | \$0.00001 `(10)`   |
| ETH/USD  | \$0.10 `(100,000)` |
| HYPE/USD | \$0.001 `(1,000)`  |
| SOL/USD  | \$0.01 `(10,000)`  |
| SUI/USD  | \$0.0001 `(100)`   |
| XRP/USD  | \$0.0001 `(100)`   |
| ZEC/USD  | \$0.01 `(10,000)`  |

## Fetching Live Values

```typescript theme={null}
import { DecibelReadDex, MAINNET_CONFIG } from "@decibeltrade/sdk";

const sdk = new DecibelReadDex({ config: MAINNET_CONFIG });
const markets = await sdk.getMarkets();

for (const market of markets) {
  const minSize = market.min_size / 10 ** market.sz_decimals;
  const lotSize = market.lot_size / 10 ** market.sz_decimals;
  const tickSize = market.tick_size / 10 ** market.px_decimals;

  console.log(`${market.market_name}: min=${minSize}, lot=${lotSize}, tick=$${tickSize}`);
}
```
