import { Account, Connection, PublicKey } from '@solarti/web3.js';
import { Market } from '@project-serum/serum';

let connection = new Connection('https://testnet.solana.com');
let marketAddress = new PublicKey('...');
let programAddress = new PublicKey("...");
let market = await Market.load(connection, marketAddress, {}, programAddress);

// Fetching orderbooks
let bids = await market.loadBids(connection);
let asks = await market.loadAsks(connection);
// L2 orderbook data
for (let [price, size] of bids.getL2(20)) {
  console.log(price, size);
}
// Full orderbook data
for (let order of asks) {
  console.log(
    order.orderId,
    order.price,
    order.size,
    order.side, // 'buy' or 'sell'
  );
}

// Placing orders
let owner = new Account('...');
let payer = new PublicKey('...'); // spl-token account
await market.placeOrder(connection, {
  owner,

}

// Settle funds
for (let openOrders of await market.findOpenOrdersAccountsForOwner(
  connection,
  owner.publicKey,
)) {
  if (openOrders.baseTokenFree > 0 || openOrders.quoteTokenFree > 0) {
    // spl-token accounts to which to send the proceeds from trades
    let baseTokenAccount = new PublicKey('...');

    await market.settleFunds(
      connection,
      owner,
      openOrders,
      baseTokenAccount,
