We are all aware that business is entirely different from trading but you can't compare the losses you get from trading to that of a business, but then if you chose to take trading as a business there's no problem cause some persons actually see gambling as a business amidst the fact that they get high counts of losses and as well get addicted so it's possible for trading as well but it's demanded that you be very watchful of your trades and again be patient enough to understand that it's not a get rich quick scheme.
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.
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.
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.
