So the question is, can one becomes addicted to trading same way gambling can be addictive?
If yes what are the sign to know that one is becoming a trading addicts?
Yes, trading is also addictive as gambling, just that the damage trading does to your mental health is way more higher than gambling, and the losses is even more severe, and due to the losses and the mental stress in trading, it's more easier to stop than gambling, but you will hardly see someone talking about it, because is quiet easy to forgo the habit.
In some cases it may be but it is not that easy to give up trading. You look at your portfolio several times a day and see how much your wealth is increasing or decreasing. It is a kind of addiction. It can be in between your daily work or in your free time. If you do not have the need to look at your portfolio, then maybe you can keep yourself in long term investments but I think you should trade regardless of profit or loss because your understanding and experience about the market will grow and with time your mental performance will become great in trading. To stay mentally calm, the amount allocated for trading should be kept in such a way that even if you lose that amount it will not negatively affect your daily activities. I do short term trading as well as long-term investments which increases the profit as you gain experience about the market conditions.
