Error Placing Ethereum Futures Order with Binance Webhook Trigger

You may encounter issues when integrating a Python script to place Ethereum futures orders using the Binance API and running it via a webhook in TradingView. In this article, we will address the error “The signature for this request is not valid” that occurs when trying to place a futures order in Binance.

Problem

In our previous setup:

• We wrote a Python script on Heroku to run a webhook via TradingView.

• The webhook sends a request to Binance’s API, which we then used to retrieve the necessary data to place a futures order.

• Unfortunately, when we try to place an order using the official Binance library (python-binance), it throws the error The signature for this request is not valid.

Solution

To resolve this issue, let’s focus on the following steps:

• Verify your TradingView API credentials: Make sure you have correctly set up your TradingView API credentials in your Heroku environment.

• Check Binance API speed limit: Refer to Binance’s official documentation for API speed limits and futures order limits to ensure we are not exceeding any limits.

Code Example

Below is an example code snippet showing how to place a futures order using the python-binance library:

import os
from binance.client import Client

Set the Binance client credentials
client_id = "YOUR_CLIENT_ID"
client_secret = "YOUR_CLIENT_SECRET"

Set the TradingView API credentials
trading_view_token = "YOUR_TRADE_VIEW_TOKEN"

Create a new Binance client instance
binance_client = client(client_id, client_secret)
def place_order(symbol, side, quantity, price):

Place a futures order
result = binance_client.placeOrder(
symbol=symbol,
side=side,
type="limit",
timeInForce="gTC"
)

Check if the order was successful entered
if not result["isSuccess"]:
print(f"Error placing order: {result['errorDetails']}")
else:
print ("Order placed successfully!")

Usage example:
place_order("ETHUSDT", "buy", 10, 1000)

Additional Tips

• Make sure to update your Heroku environment variables with the correct TradingView API credentials.

• Refer to Binance’s official documentation for updates on futures order limits and restrictions.

• Consider using a retry or error handling mechanism to handle cases where the order cannot be placed due to rate capping or other reasons.

Following these steps should help you resolve the “Signature for this request is not valid” error when placing a futures order on Binance using the Python-binance library.
