With the little knowledge I have, I have seen a lot of people scalping and making it than those that does a full trading(hours, days) but they tend to lose so easily can we say it greediness or it's not advisable generally
Full time trading is when you're completely dependant on your trades to earn a living, to put food on your table. It doesn't matter if you do that by scalping or by day trading or swinging. There are pro-traders who earn by just scalping the market and there are those who place trades and forget them for days to hit TP. Choosing any of the methods will depend on the trader's temperament. It's not just always being before a screen or pressing mobile phones that makes one a trader. It's the ability to make profit from it more than incurring losses.
