Binance: “Order’s notional must be no smaller than 5”

The “Order’s notional must be no smaller than 5” error message on Binance’s API means that the total value of the order you are trying to place is less than the minimum amount allowed, which is 5 USDT. This means that you will need to increase the size of your trade order to meet the minimum threshold. You cannot place an order with less than 5 USDT

Example:
In the following Trade we have OrderContract = 5 and Order Price = 0.1513, which give us Total Order Size = 5 * 0.1513 = 0.7565. Which is much less than 5 USDT.

Solution: Increase the order size to have Total Order Size greater than 5 USDT
