Here is a step-by-step guide that will help you manage multiple websocket connections to get prices for three cryptocurrency pairs on Binance:

Prerequisites

  • You have a Binance API account and can create an application with app_id and secret_id.
  • You have installed the websocket-client library in your Python project. If not, you can install it using pip install websocket-client.

Code

Here is some sample code that demonstrates how to connect to three different websocket streams on Binance for Bitcoin (BTC), Ethereum (ETH), and Litecoin (LTC) prices:

import websocket

import time




Ethereum: websocket multiple stream python

Replace with API credentials

api_id = "your_api_id"

api_secret = "your_api_secret"


Replace with stream URLs

stream_urls = [

"wss://binance.com/ws?symbol=BTCUSDT&type=limit&stream=order_book&limit=100",

Bitcoin

"wss://binance.us/api/v3 WebSocket API (websocket+limit+24h) ? symbol=ETHUSDT & type=order_book & stream=order_book & limit=10",

Ethereum

"wss://binance.com/ws?symbol=LTCCUSDT&type=limit&stream=order_book&limit=20"

Litecoin

]


Initialize websocket connections

ws_btc = websocket.create_connection(stream_urls[0])

ws_eth = websocket.create_connection(stream_urls[1])

ws_ltc = websocket.create_connection(stream_urls[2])


Function to update price streams

def update_price_stream(symbol, websocket):

while True:

try:


Get the current order book for the symbol

response = websocket.recv()

data = json.loads(response)

price = float(data["price"])

print(f"{symbol}: {price:.2f}")

except websocket.WebSocketException as e:

print(f"Error: {e}")


Start price stream updates

ws_btc.update_price_stream("BTCUSDT")

ws_eth.update_price_stream("ETHUSDT")

ws_ltc.update_price_stream("LTCCUSDT")


Run indefinitely until stopped

while True:

time.sleep(60)

Explanation

This code connects to three websocket streams on Binance for Bitcoin (BTC), Ethereum (ETH), and Litecoin (LTC) prices. It defines an update_price_stream function that retrieves the current price from each stream every minute. The function uses the websocket.recv() method to receive messages from the websocket connection, which contains the current order book data in JSON format.

The main part of the code creates three websocket connections using the ws_create_connection() method and starts the price update loop by calling update_price_stream for each stream.

Note: Make sure to replace your_api_id and your_api_secret with your actual Binance API credentials. Also, keep in mind that this is a simplified example and you may want to add additional error handling and logging depending on your specific use case.
