1 year ago i guess here is the problem : quantity = round(quantity)
you need to get quantity precision from API first to make the quantity to be precise enough

I'm encountering an issue when placing orders using the Binance Futures API in Python. I'm trying to place an order using the python-binance library, but I keep receiving the error 'APIError(code=-4003): Quantity less than zero.' I have calculated the order quantity based on the current price and the amount I want to trade. I have also rounded the quantity before placing the order, but I still receive the error. I believe my code adheres to the Binance API documentation, but the error persists. Here's the error: ' Calculated quantity for ETHUSDT: 0.0109421162052741 Error executing ETHUSDT BUY order: APIError(code=-4003): Quantity less than zero.'
Could anyone please help me understand what might be causing this issue and suggest a solution? Thank you in advance for your assistance! Find below the code snippet
async def create_market_order(symbol, side, quantity): try: quantity = round(quantity) order = await client.futures_create_order( symbol=symbol, side=side, type=ORDER_TYPE_MARKET, quantity=quantity, newClientOrderId=f'hma_scalpingstrategy{int(time.time())}' ) print(f"{symbol} order {side} executed at {order['avgPrice']}") except BinanceAPIException as e: print(f"Error executing {symbol} {side} order: {e}")
