I saw a sentence today, and I think it is necessary to share it.
Many brothers in the square will think that if they make a little profit every day, it will accumulate over time.
I have always disagreed with this kind of thinking. I think it is no different from tender leeks. I saw a sentence when I was reading today, which accurately described what I wanted to express.
"Linear thinking requires high-frequency sampling in the time domain. High-frequency processes must be random, and random processes cannot be superimposed."
"Operations that make a few points of profit each time are random processes, but stable profits are deterministic, and the superposition of infinite random processes cannot produce deterministic results."
What is linearization? Derivatives and integrals know it. If I want to calculate the length of a random curve, I can divide it into infinite parts, and the calculation of each part is the result. However, this kind of thinking is completely contradictory in trading, because trading introduces more time concept costs, which is why you think that you will run away after making a little profit every day, but the result is often a complete loss.
