Although part-time traders have short trading hours, if they can analyze correctly and have a trading strategy, they can also trade successfully and make good profits.
Indeed! even they spend lesser time but if they have the right sets of knowledge, they are very capable of earning decently,
No question about that. What matters the most is how you perform your trade and how you set your plan to take advantages.
The only downside is the starting point, otherwise when you are already a trader then there isn't really a big deal left for you. When starting out it is obvious that the more time you have the more you can study and test and then you can become a better trader. Without having any proper time that will end up being not so great for you and the results would not be a great situation neither. So, I would say that it is wiser to end up studying as much as you can with as many hours of the day as you can spend, no fun, no TV, no books, no entertainment of any sorts and then you will end up with something a lot better.
But after you are already good, then you can relax and just spend 3-4 hours a day max and you could still end up making a good profit, surely no matter how great you are there will be times when you lose money so do not be worried about that part, just focus on being better in the long term.
