Binance shows a loss where the trader doesn’t

The trader uses something called DCA (Dollar Cost Averaging) to ensure that losing trades are profitable in the end. You can read all about that in the strategy section. Sometimes a losing trade will be held over a daily close or even several days before it turns profitable. If this happens, then Binance will see that as an overall loss for the day since Binance is unaware of what is happening on the trader server internally. So this is nothing to worry about, simply a reporting timing difference between the trader server and Binance, the thing to focus on is the profits and the total amount of money in your exchange assets.
