Because most people are gambling, gambling on luck, gambling on luck, trading by feeling, and they don't know anything. This is not a guess, there are a pair of invisible hands supporting the bottom. Stocks, futures and foreign exchange temper minds and real traders. They must have a more thorough, in-depth and direct view of things. There are only two directions for trading, and if you choose the wrong direction, you will face losses. They are always trying to find the best time to make a good deal, so they are better at waiting like wolves grabbing food, so this makes them very calm in reality, or trading makes them remove some weaknesses in human nature. Traders are philosophers. They don't wait for a very boring entry signal. For these signals, they are only used as their own evaluation indicators and do not completely constitute the necessary conditions for their entry. They never explain what they have done with entertainment or "speculation", because in their eyes, this is an awesome market, because nothing can show their strength and value better than winning in this cruel market.
