# HIP-3 — Perpetual DEXs (/providers-market-data/hyperliquid/hip-3)



HIP-3 uses `hyperliquidf` and a `{dex}:{coin}` symbol.

## Discover [#discover]

```bash
mlab markets --exchange hyperliquidf --refresh
mlab markets --exchange hyperliquidf --symbol xyz:TSLA
```

## Read market data [#read-market-data]

```bash
mlab source orderbook --exchange hyperliquidf --symbol xyz:TSLA --depth 20
```

## Python V2 [#python-v2]

```python
candles = history.source("xyz:tsla@candles@hyperliquidf:timeframe=60")
```

There is no `--hip 3` flag. The exchange and DEX-scoped symbol identify HIP-3. Core perpetuals also use `hyperliquidf`, with a base symbol such as `BTC`.
