However, this is a profession that requires a lot of things, you need to have experience, knowledge, skills and always learn.
Many people mistakes trading for gambling, although they have some similarities which has to do with speculating (making prediction), still that of trading is different since it can be duplicated in the sense that, provided it has happened before, there's a chance it'll repeat itself again which is why it's said the market moves in circles.
We have the bear, that has to do with the price dumping and we have the accumulating stages that involves the market recovering then the bull which comes with spikes and project achieving new all time highs. If the charts are studies careful any professional traders would be able to spot this phases when they're about to start.
