Note: Question is SPECIFICALLY to experienced day traders who have been day trading for several years and spend AT LEAST four hours a day trading.
If you're day trading full time and you have all the time in the world for it...and you can only choose one of those devices, which would you choose...and most importantly, why that one instead of the others?
I will go for a laptop because it saves me the time for unnecessary back testing. Using Android will require back testing to see if price action has obeyed the set-up I'm about to trade which will require me to trade and most times even after the back testing the picture might still not dispi clearly. But with a laptop I can instantly view view previous price action just in one glance
The speed of visible was high in laptop as compared to phone and tab. The reason behind is Windows OS and it had huge processor. Which is not available in the android based tab or mobile. The transaction is also fast in laptop as compared to the phone. So use the laptops for better trading experience.
