Is probability the core of trading?

The core of trading is mathematical logic, not probability. Some people say that the profit-loss ratio is not very accurate, but should be the comprehensive result of "profit-loss ratio", "probability" and "operation method".

Suppose your winning rate is 90%, you make 9 out of 10 times and only lose 1 time, you make 1% when you make money and lose 20% when you lose, and you are losing overall. Suppose your winning rate is only 10%, you make 20% when you make money. When you lose, you lose 1%, you still make money.

If you have studied the operation methods of some trading masters, especially those who operate large funds, you will find that many masters have a very low winning rate, less than 1%. Because they use a kind of profit-making position increase and a fund management method to protect the principal with profits. For example, if you find that a product is about to fall sharply, you may only place a 10% position at the beginning, and try it out 30 times. Each time you only lose 2% of this 10%, that is, the total loss is less than 6%. You will find a big top and then make a profit and increase your position. If the market is good, you can add all your positions and make a profit of tens or hundreds of percent. If the market is not good, you can use the profit to protect the principal and save it with a small profit.

The final profit depends on the market, not personal prediction. #币安合约锦标赛
