Beginning 2021 found Andrew's book and initially didn't want to spend any money, so used my work laptop on the left running Linux.
I used IB TWS workstation for a few months, but it was quite difficult to get all the hotbuttons to work.
I stopped the paper trading, also due to work until February 2022.
I decided to go with DAS pro, and not wanting to touch windows for the last 15 years, I had no other choice.
So bought a nice new laptop with a second screen attached
Asus zenbook pro Duo
I know it's a bit expensive for £2.5K but I think for my portable solution it is good, certainly because I still have to share my space with my wife and kids on the dining table
I'm also using my son's tablet as a second extended screen, it is a bit small, but once I'm earning money with trading I'll get the latest 14" samsung tablet.
This at the moment is my only system, but same as with the tablet, once I start earning money with trading I'll invest in a fixed setup with multiple large screens, 15" and 14" laptop screens are only goood to look at 1 stock at the time.
Anyways let's see in a year the time what setup I'll have.
