### Initialize Trading Agent and Clients

Source: https://docs.o2.app/trading-agent/core-logic.html

This TypeScript code initializes the main trading agent. It loads configuration, sets up logging, and initializes clients for Bitget (price fetching) and O2 (order execution). It uses top-level await for asynchronous operations.

```typescript
import { loadConfig } from './config';
import { BitgetClient } from './bitget';
import { O2Client } from './o2';
import { createLogger } from './utils/logger';
import { BotConfig, MarketConfig } from './types/config';
import Decimal from 'decimal.js';
import { OrderSide } from '../lib/index';
import { scaleUpAndTruncateToInt, calculateBaseQuantity } from './utils/numbers';
import { shortenAxiosError } from '../lib/rest-api/utils/httpRequest';

// Constants
// Symbol for USDC/USDT pair on Bitget - used when converting prices to USDC
const USDC_USDT_SYMBOL = 'USDC/USDT';

// Load configuration from YAML file
const configPath = process.env.CONFIG_PATH || 'config.yaml';
const config: BotConfig = loadConfig(configPath);

// Main logic - wrapped in async IIFE for top-level await
(async () => {
  // Create logger with configured log level (defaults to 'info')
  const logger = createLogger(config.general?.log_level?.toLowerCase() || 'info');

  // Initialize Bitget client for fetching external price data
  const bitgetClient = new BitgetClient();

  // Initialize O2 client for placing orders on the exchange
  const o2Client = new O2Client(config.o2.base_url, config.general.network_url, logger);

  // Initialize the O2 client with session key and market contract
  await o2Client.init(config.o2.account.private_key, config.o2.market.contract_id);

  // Worker function - executes a single trading cycle (buy + sell)
  async function marketWorker(marketConfig: MarketConfig, isRunningRef: { value: boolean }) {
    // Prevent overlapping cycles - skip if previous cycle still running
    if (isRunningRef.value) {
      logger.warn(
        `Previous job still running for market ${marketConfig.base_symbol}/${marketConfig.quote_symbol}, skipping this cycle.`
      );
      return;
    }
    isRunningRef.value = true;

    logger.debug(`Starting worker for market ${marketConfig.base_symbol}/${marketConfig.quote_symbol}`);
    try {
      // Fetch market metadata from O2 (decimals, precision, etc.)
      const market = await o2Client.getMarket(marketConfig);
      if (!market) {
        logger.error(`Market not found on O2: ${marketConfig.base_symbol}/${marketConfig.quote_symbol}`);
        throw new Error('Market not found');
      }

      // Fetch reference price from Bitget
      let price: Decimal;
      try {
        // Get base price from Bitget (e.g., ETH/USDC)
        price = new Decimal(await bitgetClient.fetchPrice(marketConfig.bitget_symbol));

        // Convert to USDC if needed (e.g., FUEL/USDT -> FUEL/USDC)
        if (marketConfig.convert_to_usdc) {
          logger.debug('Converting price to USDC using USDC/USDT pair');
          const usdc_usdt_price = await bitgetClient.fetchPrice(USDC_USDT_SYMBOL);

          // Convert: (FUEL/USDT) / (USDC/USDT) = FUEL/USDC
          price = price.div(usdc_usdt_price);
        }

        // Apply reciprocal rate if needed (e.g., USDC/USDT -> USDT/USDC)
        if (marketConfig.reciprocal_rate) {
          logger.debug(`Applying reciprocal rate: 1/${price} = ${new Decimal(1).div(price)}`);
          price = new Decimal(1).div(price);
        }

        logger.info(`Fetched Bitget price for ${marketConfig.base_symbol}/${marketConfig.quote_symbol}: ${price}`);
      } catch (err) {
        logger.error(
          { err },
          `Failed to fetch Bitget price for ${marketConfig.base_symbol}/${marketConfig.quote_symbol}. Skipping this cycle.`
        );
        return;
      }

      // Calculate adjusted buy price (increase by adjustment factor to ensure fill)
      const buyPrice = scaleUpAndTruncateToInt(
        price.mul(1 + marketConfig.price_adjustment_factor),
        market.quote.decimals,
        market.quote.max_precision
      ).toString();

      // Calculate adjusted sell price (decrease by adjustment factor to ensure fill)
      const sellPrice = scaleUpAndTruncateToInt(
        price.mul(1 - marketConfig.price_adjustment_factor),
        market.quote.decimals,
        market.quote.max_precision
      ).toString();

      logger.info(
        `Final buy/sell prices: ${new Decimal(buyPrice).toString()}/${new Decimal(sellPrice).toString()} with adjustment ${marketConfig.price_adjustment_factor}`
      );

      // Calculate order quantity based on USDC value and current price
      const usdcValue = new Decimal(marketConfig.order_usdc_value);
      const quantityDecimal = calculateBaseQuantity(usdcValue, price, market.base.decimals, market.base.max_precision);
      const quantity = quantityDecimal.toString();

      // Place buy order on O2
      let buyOrderSuccess = false;
      try {
        const start = Date.now();

### Place Buy and Sell Orders on O2

Source: https://docs.o2.app/trading-agent/core-logic.html

This snippet demonstrates the process of placing buy and sell orders using the O2 client. It includes error handling for both buy and sell operations and logs the latency of each order. The sell order is attempted even if the buy order fails. Dependencies include an 'o2Client', 'marketConfig', 'OrderSide', 'logger', and a 'shortenAxiosError' function.

```typescript
buyOrderSuccess = await o2Client.placeOrder(market, buyPrice, quantity, OrderSide.Buy, marketConfig.order_type);
logger.info(
  `Buy order placed for ${marketConfig.base_symbol}/${marketConfig.quote_symbol}; price ${buyPrice}, quantity ${quantity} with latency ${Date.now() - start} ms`
);
} catch (err) {
logger.error(
  { err: shortenAxiosError(err) },
  `Buy order failed for ${marketConfig.base_symbol}/${marketConfig.quote_symbol}. Trying the sell anyways.`
);
}
if (!buyOrderSuccess) {
logger.error(
  `Buy order unsuccessful for ${marketConfig.base_symbol}/${marketConfig.quote_symbol}. Trying the sell anyways.`
);
}

// Wait between buy and sell orders (order_interval_seconds)
await sleep(marketConfig.order_interval_seconds * 1000);

// Place sell order on O2 (continues even if buy failed)
let sellOrderSuccess = false;
try {
  const start = Date.now();
  sellOrderSuccess = await o2Client.placeOrder(
    market,
    sellPrice,
    quantity,
    OrderSide.Sell,
    marketConfig.order_type
  );
  logger.info(
    `Sell order placed for ${marketConfig.base_symbol}/${marketConfig.quote_symbol}; price ${sellPrice}, quantity ${quantity} with latency ${Date.now() - start} ms`
  );
} catch (err) {
  logger.error(
    { err: shortenAxiosError(err) },
    `Sell order failed for ${marketConfig.base_symbol}/${marketConfig.quote_symbol}`
  );
}
if (!sellOrderSuccess) {
  logger.error(`Sell order unsuccessful for ${marketConfig.base_symbol}/${marketConfig.quote_symbol}`);
}
```

    let client = Client::new();
    let response = client.get(&format!("https://api.o2.app/v1/accounts?owner={}", owner_address))
