ETRADE's Developer Platform API allows automated trading, account management, and market data retrieval. Below is a sample Python program to authenticate with ETRADE and place a trade (buy stock).

🔹 Steps to Place a Trade via E*TRADE API

1. Register for API Access on E*TRADE Developer Portal.
2. Obtain OAuth1 Keys (Consumer Key & Secret).
3. Authenticate using OAuth1 to get an access token.
4. Place an Order for a sample stock (e.g., Microsoft - MSFT).

Step 1: Install Dependencies

E*TRADE API uses OAuth 1.0, so install required libraries:

pip install requests requests-oauthlib

Step 2: Python Code to Authenticate & Place a Trade

This script:

• Authenticates with OAuth 1.0.
• Fetches Account Information (for placing an order).
• Places a Market Order for MSFT.

import requests
from requests_oauthlib import OAuth1

# E*TRADE API Keys (Replace with your credentials)
CONSUMER_KEY = "your_consumer_key"
CONSUMER_SECRET = "your_consumer_secret"
ACCESS_TOKEN = "your_access_token"
ACCESS_SECRET = "your_access_secret"

# E*TRADE API URLs
BASE_URL = "https://apisb.etrade.com" # Sandbox URL (Use https://api.etrade.com for Live)
ACCOUNT_LIST_URL = f"{BASE_URL}/v1/accounts/list"
PLACE_ORDER_URL = f"{BASE_URL}/v1/accounts/{'{account_id}'}/orders/place"

# Setup OAuth1 Authentication
auth = OAuth1(CONSUMER_KEY, CONSUMER_SECRET, ACCESS_TOKEN, ACCESS_SECRET)

# Step 1: Get Account ID
response = requests.get(ACCOUNT_LIST_URL, auth=auth)
if response.status_code == 200:
 accounts = response.json()
 account_id = accounts["AccountListResponse"]["Accounts"]["Account"][0]["accountId"]
 print(f"✅ E*TRADE Account ID: {account_id}")
else:
 print("❌ Error fetching account details:", response.json())
 exit()

# Step 2: Place a Market Order for MSFT (Buy 5 Shares)
order_payload = {
 "PlaceOrderRequest": {
 "orderType": "EQ", # Equity Order
 "clientOrderId": "123456789", # Unique ID for Order
 "orderAction": "BUY",
 "quantity": 5,
 "symbol": "MSFT",
 "priceType": "MARKET", # Market Order
 "orderTerm": "GOOD_FOR_DAY",
 "marketSession": "REGULAR"
 }
}

response = requests.post(PLACE_ORDER_URL.format(account_id=account_id), json=order_payload, auth=auth)

# Step 3: Check Response
if response.status_code == 200:
 order_info = response.json()
 print("✅ Order Placed Successfully:", order_info)
else:
 print("❌ Order Placement Failed:", response.json())

🔹 How This Works

1. Authenticates using OAuth1.
2. Fetches your Account ID.
3. Sends a Market Order for 5 shares of MSFT.

✅ Enhancements

• Stop-Loss & Take-Profit:

  "stopPrice": 390.0 # Stop-loss at $390
  

• Trailing Stop Orders for dynamic risk management.
• Paper Trading Mode with Sandbox API before Live Trading.
