There is no need to ask how as it was too obvious that the video is fake. In fact, how could you imagine a wrong answer becoming right? How could you imagine that even if you lose, you still win?

Don't overlook the situation not think that all you have seen on YouTube and these social media influencers are true, many of them are fake. Because there is no way to earn money from a losing trade but rather expect losses. That video has no intention to educate people but it made it fool viewers like you. Stop thinking about it as it only bothered your mind instead, help yourself to understand that trading is not always profitable.
