If you become a "pro" you will have many advantages in the office, provided that it's a good place and your peers are ok. One disadvantage is the inherent presure to trade every day. You are coming in every day and paying a desk fee. Everyone around you trades so you must do something. I find that for me there are opportunities not every day buy one a week maybe more but I wish do to other things in my life that stare at a screen. You could scalp every day as well we know "things move". But may not be a sustainable strategy if you pay commission. All in all for a swing trader or even a system or position trader an office will be no advantage but a hinderance. If you are a 1/4-1/2 point scalper you can trade a lot and maybe go for a bit larger moves in size well you can make more money that in any paying job if successful.
Onsite (now AB Watley) followed this unstated policy, through all sorts of stupid stategies, that caused those whom I saw, blow out their funded accounts, and other blow out their own accounts. Seems that through time, the atmosphere was caustic, abrassive, and they shrewdly rewarded (through attention, praise and other non-verbal communications) those whom generated large tickets through frequency totally irrespective of whether you were net positive on the day, week, month, quarter, year of lifetime. well said
