Programmatic API

import { BinanceSkill, getBinanceSkill } from '@openclaw/binance';

// Create skill instance
const skill = getBinanceSkill('default');

// Check connection
const connected = await skill.isConnected();

// Get prices
const price = await skill.getPrice('BTCUSDT');
const prices = await skill.getPrices(['BTCUSDT', 'ETHUSDT']);
const ticker = await skill.get24hrTicker('BTCUSDT');

// Get balances
const balances = await skill.getBalances();
const btcBalance = await skill.getBalance('BTC');

// Place orders
const buyOrder = await skill.marketBuy('BTCUSDT', '0.001');
const sellOrder = await skill.marketSell('BTCUSDT', '0.001');
const limitOrder = await skill.limitBuy('BTCUSDT', '0.001', '50000');

// Manage orders
const openOrders = await skill.getOpenOrders();
const order = await skill.getOrder('BTCUSDT', 12345678);
const cancelled = await skill.cancelOrder('BTCUSDT', 12345678);

// Get order history
const history = await skill.getOrderHistory('BTCUSDT', { limit: 50 });

// Get local trade history
const trades = await skill.getLocalTradeHistory({ symbol: 'BTCUSDT', limit: 10 });

// Add notes to trades
await skill.addTradeNotes(12345678, 'Entry point for long position');

// Get candlestick data
const klines = await skill.getKlines('BTCUSDT', '1h', { limit: 100 });

// Cleanup
await skill.close();

Order Types

Market Orders

• Execute immediately at the best available price
• Use marketBuy() and marketSell() methods
• No price control, guaranteed execution

Limit Orders

• Execute only at the specified price or better
• Use limitBuy() and limitSell() methods
• Price control, but no guaranteed execution
• Time in force options: GTC (Good Till Cancelled), IOC (Immediate or Cancel), FOK (Fill or Kill)

Advanced Order Types

The skill also supports STOP_LOSS, STOP_LOSS_LIMIT, TAKE_PROFIT, and TAKE_PROFIT_LIMIT orders via the createOrder() method.

Data Storage

Trade history is stored locally in SQLite:

• Location: ~/.openclaw/skills/binance/trades.db
• Tables:
  • trades: Local copy of all orders with notes
  • price_history: Historical price snapshots

Safety Considerations

1. Testnet First: Always test strategies on testnet before using real funds
2. API Permissions: Use API keys with minimal required permissions
3. IP Restrictions: Consider restricting API keys to specific IP addresses
4. Withdrawal Disabled: For trading-only keys, disable withdrawal permissions

Environment Variables

This skill uses the binance-auth skill for credentials. No direct environment variables required.

Error Handling

Common errors and solutions:

• "Not connected to Binance": Run binance-auth-cli connect first
• "Account does not have trading permissions": Your API key lacks SPOT trading permission
• "Invalid API key": Check your API key in binance-auth
• "Insufficient balance": Not enough funds for the order

Dependencies

• @openclaw/auth-provider: Authentication provider
• @openclaw/binance-auth: Binance authentication skill
• sqlite3: Local database for trade history
