Orderbook

Orderbooks are not loaded by default to make the load experience faster.

However, it is possible to load the specific orderbook, or subscribe to the changes.

const {asks, bids} = await zoUser.getOrderbook('SOL-PERP')
console.log(asks)

[
  [ 40.43, 0.01 ],
  [ 40.48, 1.65 ],
  ...
]

console.log(bids)

[
  [ 40.38, 31.76 ],
  [ 40.24, 1.65 ],
  ...
]

bids, asks array of arrays where each entry represents [price, size]

here is a simple way to make sure that orderbook data remains up to date

    await zoUser.state.subscribeToOrderbook('SOL-PERP')
    await zoUser.state.subscribeToAllOrderbooks()
    await zoUser.state.unsubscribeFromAllOrderbooks()
