Hi, @yanweidong
This problem arises from a precision error. When we try to buy using all USDT, sometimes the calculated amount to buy multiplied by the price exceeds the total USDT available (e.g., 1000 / 20.5 = 48.7804878049, and then the bot tries to validate: 48.7804878049 * 20.5 > 1000).

As an easy fix in the paper wallet mode, you can buy using all USDT(quote) minus $1 here

amount := quotePosition / closePrice // calculate amount of asset to buy
