There is no minimum and maximum time to spend in trading per day, it all depends on the type of trader and the strategy you are using. If you swing and trade regularly, you spend 2-3 hours the first time you trade to learn charts and other things and less time thereafter to check orders regularly, but the daily trader spends a lot of time every day because he orders and close it on the same day. and now i am a beginner so we have to give more and more time. But I am a student so I took this business first time. But I take it next time full. A time trader must give 6 hours in this business. And full-time traders must be 12 hours. I think that's enough for all. If anyone gives 12 hours with his strategy and destroys it, then he will earn here more and more money obediently.
