Your sell trade value is lower than your buy trade because Binance deducts the trading fee directly from your open position amount. This means a small portion of your coins gets used to pay the fee, so the full amount is never sold. The leftover amount is called "dust" — a balance too small to trade.
Solutions
There are two ways to handle this:
Use BNB to pay trading fees
On Binance, you can set your account to pay trading fees with BNB instead of deducting them from your position. This keeps your position amount intact and saves you 25% on trading fees. You do need to hold BNB on your Binance account for this to work.Convert dust to BNB with the Wallet scrubber
If you already have dust balances, you can convert them to BNB using the Wallet scrubber. Go to your Dashboard, scroll down, and on the right side you'll find Current assets. Open the Wallet scrubber tab and select Convert dust to BNB.
