In the context of similarity it is clearly different because business and trading have different levels of risk.
If someone treats trading like a business and they do not have good knowledge then it will not last long because every time we trade we need money and if someone is losing continuously then it is impossible to stay in that position.
You will never be good at something only by learning that is good but not enough. Without knowledge, you are like a blind person wants to try, bet and wait for luckiness to succeed. There is very small chance or nearly impossible to succeed like this, without knowledge, be greedy enough, and ready to take high risk.
The principle is you must learn first, practice a lot, before you can master in something and start to succeed and in trading it's time to get profit. However, trading is more dangerous, and even you have knowledge, experience in trading, you can still be a loser and can not be a winner because in a market, 80% or up to 90% of traders lose money in trading.
Trading plays on psychology and tends to force someone to see the potential to enter or take profit and if the trading skills are bad then it will be problematic.
Mastering the
psychology of market cycle is a good start with learning, to help you control your emotion and psychology better in this volatile market.
The biggest mistake because some people think they can get rich in a short time in trading so they force to achieve it all with limited knowledge and end up losing.
They will understand that they are wrong with their trading experience, and with money loss in trading.
