This is pure psychology and it is probably the hardest thing to master.
People shouldn't even attempt to master it. It's way better to focus on reliable forms of income rather than something so flashy and tricky as trading.
Trades in most cases end up being a disappointment, regardless of the outcome. If you buy at $100 and the price falls to $70 you are disappointed. If you buy at $100 sell at $120 but the price goes up to $150 you are yet again disappointed. In other words, the nothingness in trading continues for as long as you keep traing.
I do occasionally watch all these bigshots on youtube pulling out their charts and draw lines in all sorts of directions. You know what my thought is? Get a life. Seriously. Some times they have drawn so many lines and triangles, that you can't even see the base chart anymore, lol.
trading is a game of mind and patience so if you dont have any patience to do it then dont go because in the end you have a huge chance that you might lose most of your capital in trading. You are right whatever movement that market goes a trader will get disappointed.
