Streamlining OKX API Transactions with Python

Introduction to OKX Trade Tools

OKX Trade Tools simplify interactions with the OKX exchange API by encapsulating frequently used functions for spot trading (SPOT) and perpetual contracts (SWAP). This Python library significantly reduces the complexity of algorithmic trading implementation.

Installation Guide

To install the OKX Trade library:

Ensure Python 3.7+ is installed on your system
Run the following command in your terminal:
```
pip install okx-trade
```

Getting Started

Example 1: Spot Trading BTC-USDT

This example demonstrates placing a limit order to buy BTC at 2% below current market price:

from okx_trade import OkxSPOT
from pprint import pprint

okxSPOT = OkxSPOT(
    key='API_KEY',
    secret='SECRET_KEY',
    passphrase='PASSPHRASE'
)

instId = 'BTC-USDT'
askPx = float(okxSPOT.market.get_ticker(instId)['data']['askPx'])
openPrice = askPx * 0.98  # 2% below current price
result = okxSPOT.trade.open_limit(
    instId=instId,
    openPrice=openPrice,
    openMoney=10000,
    timeout=7200,
    cancel=True
)
pprint(result)

Example 2: Perpetual Contract Trading

This example shows how to place a limit order for BTC-USDT-SWAP with isolated margin and 10x leverage:

from okx_trade import OkxSWAP

def order_callback(information):
    print("Order executed:", information)

okxSWAP = OkxSWAP(
    key='API_KEY',
    secret='SECRET_KEY',
    passphrase='PASSPHRASE'
)

askPx = float(okxSWAP.market.get_ticker('BTC-USDT-SWAP')['data']['askPx'])
result = okxSWAP.trade.open_limit(
    instId='BTC-USDT-SWAP',
    openPrice=askPx * 0.95,
    tdMode='isolated',
    posSide='long',
    lever=10,
    openMoney=10000,
    timeout=7200,
    callback=order_callback
)
