What this error means
When your bot encounters the error "-1111 Parameter 'quantity' has too much precision" on Binance, it means the order cannot be placed because the quantity contains too many decimal places for Binance to accept.
Why this happens
Binance enforces strict rules on the number of decimal places allowed in an order quantity. If the calculated quantity exceeds that limit, Binance rejects the order.
