Answer

Remember to clear your interval

const [seconds, setSeconds] = useState(60);
useEffect(() => {
    const intervalId = setInterval(() => {
      setSeconds((prevState) => {
        if(prevState === 1) clearInterval(intervalId)
        return prevState - 1;
      });
    }, 1000);
}, [state.Trade.length]);
