I dont know whats worse, your statement or that so many people liked it.
Trading is a serious and difficult business, it leaves little room for errors.
How can you 'see a real good opportunity' while you are distracted doing those other two things?
I understand this might not work for many or most. It depends on your personality and your type of trading.
I am a person who likes to be busy and to have fun. In a trading environment like 2008 or even 2015, where I had a possible trade every few minutes in FESX and FDAX, it was not necessary for me to utilize any distractions like videogames to not get bored. The market was like a fast videogame himself, very fun, with lots of action to trade.
These days there are also fantastic opportunities, but only maybe 5-10 during my full trading day, which gives me on average a trade every 1-2 hours.
My style is VERY simple, I dont need to rethink or analyze my trading opportunities once they are there. I just click the mouse. Enter. Click again. Exit. Thats it.
Because of this combination, the simplicity of my approach, the frequency of opportunities in the market and myself wanting to be engaged in some kind of action, I chose the distractions I mentioned before, among others. Reading and posting on Elitetrader is another welcome distraction between trades. Thats one of the reasons why I am on this forum.
I understand that this is not for everybody. If you have a different trading style or personality, what I do might seem or be complete nonsense or even dangerous for your account. So be it the market or Battlefield... play at your own risk
