The first person that I checked that has opened a position for 90 days is making money. Some people that copied him is making money also but some people are losing money while copy him. There are people that copied him but make no money but not losing yet at the time I snapped this.
Let a trading position opens for 90 days is very bad in my opinion.
In this volatile market, one of most important principle is don't let your trading position opens like forever and only wait to get profit from it. You must identify when you have to close your position, before you open it. If you are trading with leverage, this principle is more important as it can help you to exit the market and proactively avoid liquidations.
