I don't think trading is a job. Because for me real job is where you can make money daily from your hard work and effort. But trading is different, there's no guarantee that you can always make money, and you must always used capital for every trade and aside from that there's a risk of losing it. So for me, it's better to say trading is a business because it always has a risk same with trading. Despite of that, if the trader is not profitable and keep losing funds because they trade out of nowhere from the chart then it's called gambling, not a business.
Indeed, there is no guarantee that trading can produce the profits we want, the risk of losses is that you will definitely lose there. I think the term trading is the same in my opinion, whether it's work or business, it's just a term, but both terms are the same as doing a target analysis to be able to make a profit. I think if we want to make money we don't always have to look in real life, but with advances in technology like today, making money can be done anywhere, whether in the virtual world (internet).
