import requests import json import hmac import hashlib import time

API endpoint

url = "https://fapi.binance.com/fapi/v1/order"

API key and secret

api_key = "" api_secret = ""

Request parameters

symbol = "BTCUSDT" side = "SELL" type = "MARKET" notional_value = 30 # Notional value in USD timestamp = int(time.time() * 1000) recvWindow = 5000

Fetch last traded price

ticker_url = "https://fapi.binance.com/fapi/v1/ticker/price" ticker_payload = { "symbol": symbol } ticker_response = requests.get(ticker_url, params=ticker_payload) last_price = float(ticker_response.json()["price"])

Calculate quantity

quantity = notional_value / last_price

Create the timestamp

timestamp = int(time.time() * 1000)

Create the signature

message = f"{timestamp}{recvWindow}".encode('utf-8') signature = hmac.new(api_secret.encode('utf-8'), message, hashlib.sha256).hexdigest()

Create the request payload

payload = { "symbol": symbol, "side": side, "type": type, "quantity": quantity, "timestamp": timestamp, "recvWindow": recvWindow, "signature": signature }

Send the request

response = requests.post(url, headers={"X-MBX-APIKEY": api_key}, json=payload)

Print the response

print(response.json())

Even i am facing the same error any possible solution?

i tried setting useServerTime()

[drinkthere]

check this issue, when useServerTime() returns NaN, timestamp in following request will be invalid. maybe it's the reason. https://github.com/jaggedsoft/node-binance-api/issues/472
