Below is a basic Python script to get you started with placing trades using the Binance WebSocket Spot API.

First, ensure you have the necessary libraries installed. You can install them using pip:

pip install websocket-client
pip install hmac
pip install hashlib

Here’s a simple script to connect to the Binance WebSocket API and place a trade:

import json
import hmac
import hashlib
import time
import websocket

API_KEY = 'YOUR_API_KEY'
SECRET_KEY = 'YOUR_SECRET_KEY'

def on_message(ws, message):
    print(f"Received message: {message}")

def on_error(ws, error):
    print(f"Error: {error}")

def on_close(ws):
    print("### closed ###")

def on_open(ws):
    def run(*args):
        # Creating a payload for placing an order
        payload = {
            "method": "order.place",
            "params": {
                "symbol": "BTCUSDT",
                "side": "BUY",
                "type": "MARKET",
                "quantity": 0.001  # Specify the quantity you want to buy
            },
            "id": 1  # ID can be any unique identifier
        }
        
        # Creating the signature
        timestamp = int(time.time() * 1000)
        query_string = f'timestamp={timestamp}'
        signature = hmac.new(SECRET_KEY.encode('utf-8'), query_string.encode('utf-8'), hashlib.sha256).hexdigest()
        
        # Adding the signature and API key to the payload
        payload["params"]["signature"] = signature
        payload["params"]["timestamp"] = timestamp
        payload["params"]["apiKey"] = API_KEY
        
        # Sending the payload to the WebSocket
        ws.send(json.dumps(payload))
        print("Order placed")

    run()

if __name__ == "__main__":
    websocket.enableTrace(True)
    ws = websocket.WebSocketApp("wss://ws-api.binance.com:443/ws-api/v3",
                                on_open=on_open,
                                on_message=on_message,
                                on_error=on_error,
                                on_close=on_close)
    ws.run_forever()

Replace YOUR_API_KEY and YOUR_SECRET_KEY with your actual Binance API key and secret key. This script places a market buy order for 0.001 BTC/USDT when the WebSocket connection opens.
