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?
If i am day trader, so i must be online much and not much doing something outside my house so my device is laptop. Beside that, laptop is like PC when we need to do it outside, and i think as a trader, bring laptop anywhere is not be a matter. But for price alarm i use mobile phone, laptop only if want to see chart and make an order.
