Getting Started

Getting started with bingx-python is a straightforward process. This section will guide you through the installation of the library and the initial setup of the client.

Installation

The library can be easily installed using pip, the Python package manager. Open your terminal or command prompt and enter the following command:

pip install bingx-python
Enter fullscreen mode Exit fullscreen mode

Alternatively, if you want to work with the latest development version, you can clone the repository from GitHub and install it from the source:

git clone https://github.com/tigusigalpa/bingx-python.git
cd bingx-python
pip install -e .
Enter fullscreen mode Exit fullscreen mode

Obtaining API Keys

Before you can start using the library, you will need to obtain an API key and secret key from the BingX website. Here is how you can do that:

  1. Log in to your BingX account and navigate to the API settings page.
  2. Click on the "Create API" button.
  3. Give your API key a descriptive name and configure the necessary permissions. For security reasons, it is recommended to only grant the permissions that are absolutely necessary for your application.
  4. Click on the "Create" button. Your API key and secret key will be displayed. Make sure to save them in a secure location, as the secret key will only be shown once.

Initializing the Client

Once you have your API key and secret key, you can initialize the BingXClient. The client is the main entry point for interacting with the BingX API. Here is how you can initialize it:

from bingx import BingXClient

# Initialize the client
client = BingXClient(
    api_key="your_api_key_here",
    api_secret="your_api_secret_here",
)
Enter fullscreen mode Exit fullscreen mode

Make sure to replace "your_api_key_here" and "your_api_secret_here" with your actual API key and secret key. It is highly recommended to use environment variables or a configuration file to store your API keys, rather than hardcoding them in your code.

Usage

Now that you have installed the library and initialized the client, let's explore some of the common operations you can perform with bingx-python. The library is organized into a number of services, each of which corresponds to a different area of the BingX API.

Market Service

The Market Service provides access to a wide range of market data, including real-time prices, order book depth, and candlestick data. Here are some examples of how you can use the Market Service:

Getting the Latest Price

You can get the latest price of a trading pair using the get_latest_price() method:

# Get the latest price of BTC-USDT
price_data = client.market().get_latest_price("BTC-USDT")
price = price_data['data']['price']
print(f"The latest price of BTC-USDT is: {price}")
Enter fullscreen mode Exit fullscreen mode

Getting the Order Book

The order book, or depth, provides a snapshot of the current buy and sell orders for a trading pair. You can get the order book using the get_depth() method:

# Get the order book for BTC-USDT
depth = client.market().get_depth("BTC-USDT", 20)
print(depth)
Enter fullscreen mode Exit fullscreen mode

Getting Candlestick Data

Candlestick data, or klines, provides a historical view of the price of a trading pair. You can get candlestick data using the get_klines() method:

# Get the last 100 1-hour candles for BTC-USDT
klines = client.market().get_klines("BTC-USDT", "1h", 100)
print(klines)
Enter fullscreen mode Exit fullscreen mode

Account Service

The Account Service allows you to manage your BingX account, including checking your balance, viewing your open positions, and setting your leverage.

Getting Your Account Balance

You can retrieve your account balance using the get_balance() method:

# Get your account balance
balance = client.account().get_balance()
print(balance)
Enter fullscreen mode Exit fullscreen mode

Getting Your Positions

To see your current open positions, you can use the get_positions() method:

# Get all open positions
positions = client.account().get_positions()
print(positions)

# Get positions for a specific symbol
btc_positions = client.account().get_positions("BTC-USDT")
print(btc_positions)
Enter fullscreen mode Exit fullscreen mode

Setting Leverage

You can adjust the leverage for a specific symbol using the set_leverage() method:

# Set leverage for BTC-USDT to 10x for both long and short positions
client.account().set_leverage("BTC-USDT", "BOTH", 10)
Enter fullscreen mode Exit fullscreen mode

Trade Service

The Trade Service is the heart of any trading bot, and bingx-python provides a comprehensive set of methods for placing and managing orders.

Placing an Order

You can place a new order using the create_order() method. This method accepts a dictionary of order parameters, including the symbol, side (buy or sell), type (market or limit), and quantity.

# Place a market buy order for 0.001 BTC
order = client.trade().create_order({
    "symbol": "BTC-USDT",
    "side": "BUY",
    "type": "MARKET",
    "quantity": 0.001
})
print(order)

# Place a limit sell order for 0.01 ETH at a price of 3000 USDT
limit_order = client.trade().create_order({
    "symbol": "ETH-USDT",
    "side": "SELL",
    "type": "LIMIT",
    "quantity": 0.01,
    "price": 3000
})
print(limit_order)
Enter fullscreen mode Exit fullscreen mode

The library also provides convenient "quick methods" for placing common order types:

# Place a spot market buy order
client.trade().spot_market_buy("BTC-USDT", 0.001)

# Place a futures market long order
client.trade().futures_long_market("BTC-USDT", 100, 10) # 100 USDT worth, 10x leverage
Enter fullscreen mode Exit fullscreen mode

Managing Orders

Once you have placed an order, you can manage it using the methods provided by the Trade Service.

# Get a list of your open orders
open_orders = client.trade().get_open_orders("BTC-USDT")
print(open_orders)

# Cancel a specific order
client.trade().cancel_order("BTC-USDT", "order_id_to_cancel")

# Cancel all open orders for a symbol
client.trade().cancel_all_orders("BTC-USDT")
Enter fullscreen mode Exit fullscreen mode

WebSocket Streaming

For applications that require real-time data, bingx-python provides a powerful and easy-to-use WebSocket client. The WebSocket client allows you to subscribe to a variety of data streams, including trades, klines, and order book depth.

Here is an example of how you can use the MarketDataStream to subscribe to real-time trade and kline data for BTC-USDT:

from bingx.websocket import MarketDataStream

# Define a message handler
def on_message(data):
    print(f"Received: {data}")

# Create a market data stream
market_stream = MarketDataStream()
market_stream.connect()

# Subscribe to trade and kline streams
market_stream.subscribe_trade("BTC-USDT")
market_stream.subscribe_kline("BTC-USDT", "1m")

# Set the message handler and start listening for messages
market_stream.on_message(on_message)
market_stream.listen_async()
Enter fullscreen mode Exit fullscreen mode

The library also provides an AccountDataStream for receiving private account updates, such as balance changes and order updates.

Error Handling

Robust error handling is crucial for building reliable trading applications. bingx-python provides a set of custom exceptions that make it easy to handle different types of errors that may occur when interacting with the BingX API.

The base exception class is BingXException, and all other exceptions inherit from it. This allows you to catch all library-specific errors with a single except block. The library also provides more specific exceptions for common API errors, such as AuthenticationException, RateLimitException, and InsufficientBalanceException.

Here is an example of how you can use a try...except block to handle potential errors when fetching your account balance:

from bingx.exceptions import (
    BingXException,
    APIException,
    AuthenticationException,
    RateLimitException,
    InsufficientBalanceException
)

try:
    balance = client.account().get_balance()
except AuthenticationException as e:
    print(f"Authentication Error: {e}")
except RateLimitException as e:
    print(f"Rate Limit Exceeded: {e}")
except InsufficientBalanceException as e:
    print(f"Insufficient Balance: {e}")
except APIException as e:
    print(f"API Error: {e}")
except BingXException as e:
    print(f"An unexpected error occurred: {e}")
Enter fullscreen mode Exit fullscreen mode

By using these custom exceptions, you can write more granular and effective error handling logic in your applications.

Advanced Features

Beyond the core functionalities, bingx-python also supports more advanced features for sophisticated trading strategies.

Coin-M Perpetual Futures

In addition to the standard USDT-margined futures, the library provides full support for Coin-M perpetual futures. These contracts are margined and settled in cryptocurrency (e.g., BTC, ETH) instead of a stablecoin. The coinm client provides a dedicated set of methods for interacting with these markets.

# Get the ticker for a Coin-M contract
ticker = client.coinm().market().get_ticker("BTC-USD")
print(ticker)

# Place a market order for a Coin-M contract
order = client.coinm().trade().create_order({
    "symbol": "BTC-USD",
    "side": "BUY",
    "positionSide": "LONG",
    "type": "MARKET",
    "quantity": 100
})
print(order)
Enter fullscreen mode Exit fullscreen mode

Sub-Account Management

For traders who manage multiple portfolios, the Sub-Account Service is an invaluable feature. It allows you to create and manage sub-accounts, transfer assets between them, and manage their API keys programmatically.

# Create a new sub-account
sub_account = client.sub_account().create_sub_account("MyNewSubAccount")
print(sub_account)

# Transfer assets from the main account to a sub-account
client.sub_account().internal_transfer(
    "main_account_uid",
    "sub_account_uid",
    "USDT",
    100
)
Enter fullscreen mode Exit fullscreen mode

Architecture and Project Structure

Understanding the architecture of bingx-python can help you use it more effectively and contribute to its development. The library is organized into a clean and logical structure, with a clear separation of concerns between the different modules.

The main package is located in the bingx/ directory and is organized as follows. The client.py file contains the main BingXClient class, which is the primary entry point for the library. The coinm_client.py file contains the CoinMClient class, which provides access to the Coin-M perpetual futures API. The exceptions.py file contains the custom exception classes. The http/ directory contains the base HTTP client, which handles request signing and other low-level HTTP operations. The services/ directory contains the individual service modules, one for each area of the BingX API. Finally, the websocket/ directory contains the WebSocket client modules.

This modular architecture makes the library easy to extend and maintain. If BingX adds new features to its API, it is straightforward to add new methods to the existing service modules or create new ones.
