零和博弈

Today let's talk about a trading strategy that is easily overlooked---the mindset of the opponent. Everyone knows that every penny earned in trading is the cost of the opponent's cognitive bias. The market itself is a zero-sum game arena; there is no gift without reason.

However, most people rarely consider why the opponent is selling before placing an order. Why, when I judge the price to be cheap and choose to buy, does the opponent think it's really expensive and quickly sell to me?

Of course, please believe that the opponent also has sufficient reasons to sell, just like you.

So, it is important to effectively utilize the mindset of the opponent. There is no absolutely correct trade, only unrecognized weaknesses of the opponent. When you place an order, first ask, who is on the other side? Why are they more foolish than me?
