Buy side output does not make sense

[KobaKhit]

Hello. So I set my code up to execute orders on Binance US and whenever I submit an order to buy ETH for USDT the trade_status response does not make sense to me.

smart_order_response = api_client.create_trade(
            user_id,    # user_id
            account_id, # account_id
           'USDT',            # from_symbol
           'ETH',           # to_symbol
           150.27,         # amount of from_symbol
            True              # enable smart_routing
        )

I would assume that usdValue in 'fills' should sum up close to 150.27. I don not understand why it would not. And when I check my balance after the trade completed the actual amount transfered is 142.87 and I dont see that number in the trade_status response and even nativeValue is wayoff from what I expected.

   'usdValue': 11.905482300000001,

I would like to avoid hitting the balance endpoint after every trade to see what was the actual amount transfered from coin to coin. I am sure there is detail I missing. Looking forward to any help.
