Just started day trading 2 months ago. I've been using TWS but find it super slow. However, I do love it's news triangles on chart which makes me very secure. (Before using that there was once breaking news came in and I was still trading my pattern and strategy and lost some money. (Also didn't have a stop loss hot key.) I also like TWS's sophisticated scanner.
This week I just started trying DAS on Parallel with 8 charts (4 stocks) on one screen (27'' iMac 5K). So far very smooth. I feel like this is easier than back and forth with a couple of screens and extra PC, desk and space since I have everything on one big screen. I also have my laptop next to it for chatroom, news, etc.
I'm in Asia trading at night so prefer dark charts.
I understand there is a risk brought on with extra software. I had my Mac workstation properly setup, and for the time being, I don't see a point in investing extra hardwares and space in my apartment since I'm still on simulation. At this day and age who says trading has to be done on PC and Windows? Of course, this will probably come back and bite me in the long run.
