Binance not trading full balance

[truamd]

Hi Guys

i have been having moderate success with the bot,but am finding a strange issue, i am trading in USDT/BTC, but when the bot creates a sticky buy and fills it, so buys btc with usdt, there is always a balance left behind in the usdt account, it never seems to do a 100% buy.

Any ideas?


Thank you in advance
