I am trying to create a market order with coin futures ETH USD pair. I have 0.02 ETH in my account,

main error quantity is less than zero from binance but when ccxt calls binance we are passing quantity 0, so it looks precision and limits is problem

limits for ETHUSD : {‘amount’: {‘min’: 1.0, ‘max’: 100000.0}, ‘price’: {‘min’: 0.01, ‘max’: 100000.0}, ‘cost’: {‘min’: None, ‘max’: None}, ‘market’: {‘min’: 1.0, ‘max’: 100000.0}}

Precision for ETHUSD: {‘base’: 8, ‘quote’: 8, ‘amount’: 0, ‘price’: 2}

it looks it fails below condition: Order amount >= limits[‘min’][‘amount’]

does that mean we can’t create an order for ETHUSD for less than 1 ETH?

It was working earlier with 1$ also. Binance suddenly changed the rule. We got panicked in the team. It got clarified now.
