I have a friend is a trader, he's good trader with big account in hotforex, and he uses 4 monitors (3 PC and 1 laptop) for trading. If prepare for your trading better, your trading would be better for sure. Don't know whether he use smart-phone for trading or not.
Haha!
My post meant using smartphone to trade is not good. The smartphone-screen is smaller than monitor. And one good trader has even 4 monitor for his trading, that means using a lot of monitor with large screens, it's sure good for your trading.
now this makes me feel like my monitor is not enough! LOL but i guess the bigger the better, I might as well try hooking my PC to a smart TV and see how it works i mean, if you got a 52 inch screen that would be really awesome
