How to Get Real-Time Prices for Perpetual Contracts Using Python and ccxt with OKX API

·

To fetch real-time prices for perpetual contracts using Python with the ccxt library and OKX API, follow these steps:

Step 1: Install the ccxt Module

pip install ccxt

Step 2: Write Python Code to Fetch Real-Time Prices

import ccxt

# Initialize the OKX exchange object
exchange = ccxt.okx({
    'apiKey': 'YOUR_API_KEY',
    'secret': 'YOUR_SECRET',
    'enableRateLimit': True,
})

# Fetch all trading pairs' current prices
tickers = exchange.fetch_tickers()

# Filter for perpetual contracts (symbols containing 'SWAP')
perpetual_tickers = {
    symbol: ticker['last'] 
    for symbol, ticker in tickers.items() 
    if 'SWAP' in symbol
}

# Output current prices for perpetual contracts
for symbol, price in perpetual_tickers.items():
    print(f"{symbol} Current Price: {price}")

In this example, we:

  1. Create an OKX exchange object with rate limiting enabled
