Ethereum: Trading Latest Futures Prices on Binance WebSocket
As a developer working with Ethereum and the Binance API, getting real-time price data is essential for building effective trading strategies. In this article, we will explain how to get the latest futures prices using the Binance WebSocket API.
Prerequisites
- You have created a Binance account and obtained an API key.
- You have installed the required libraries: python-binance and websocket-client.
Step-by-step guide
- Initialize Binance Socket Manager
import binancesocket as bss
BinanceWS = bss.BinanceSocketManager(binance_info=binance_info)
`
Replace binance_info with your actual Binance API key and secret.
- Establish a connection to the WebSocket server
conn_key = 'your_api_key_here'
conn_secret = 'your_api_secret_here'
bss.connect(wss='wss://api.binance.com/truehost', key=conn_key, secret=conn_secret)
Replace ‘wss’ with your Binance WebSocket server URL.
- Subscribe to the futures market
symbol = 'BTCUSD'
subscribes = bss.Subscribed(symbol=symbol)
subscribes.subscribe()
This will subscribe to the Bitcoin USD futures market on the Binance exchange.
- Get the latest prices for trading
latest_prices = subscribes.get_all_tickers()
for ticking with latest prices:
print(f"{ticker.ymbol} last price: {ticker.price}")
Remember that we are only interested in futures whose columns end in “_USD” (e.g. “BTCUSDT”, “ETHUSDT”, etc.). If you want to get all futures, uncomment this line:
all_tickers = subscribes.get_all_tickers()
ticker in all_tickers:
print(f"{ticker.ymbol} last price: {ticker.price}")
Sample Output
BTCUSDT last price: 40000.0
ETHUDT last price: 42000.0
...
- Close the subscription and disconnect from the WebSocket server
subscribes.close()
bss.disconnect()
Remember to close the subscription when you are done using it to avoid unnecessary API requests.
After following these steps, you should get the latest futures prices on the Binance WebSocket server. Happy trading!
