What is the difference between a sophisticated trader and a gambler? (contract mentality)

Mature traders are not like gamblers, but more like casinos. It's the same in every way except that I can't pump water. Gamblers go to casinos to play. Sometimes they make money, sometimes they keep them company, but they basically leave the casino with nothing. Because most gamblers have no rules and no system, they can play whatever they want and how big they want, just on their whim. And how does the casino work? First of all, the odds range of each gambling game is well known. Secondly, each gambling game has a betting limit, so there will be no chance of losing money to the point of closing the door. Thirdly, the funds are dispersed to multiple independent gambling games related to the account. , the probability of losing every bet is extremely low. Therefore, the casino has created a system for itself that does not produce large losses and balances the winning rate, odds, and frequency of different gambling risks. Under this system, daily profits and losses fluctuate within a safe range, which will definitely happen as the number of rounds continues to increase. Daying takes funding to a new level. The capital curve of mature traders is basically the same. #交易哲学 #合约
