Seeing someone post about the uselessness of academic qualifications really makes me laugh. Academic qualifications do not equal understanding, but reading more can definitely improve understanding.

In other fields, deep thinking may not be a necessary condition, but in the case of secondary trading, it seems to involve just pressing the buy and sell buttons, yet behind that are countless instances of deep thinking and practice, which can form the basic underlying logic and dynamic thinking (what is the structure?) rather than static thinking (is it rising or falling?)

Traders who achieve long-term stable profits (not the kind that get rich today and go bankrupt tomorrow) usually do not have very low academic qualifications.
