Don’t Reinvent the Market. Model What Already Works.
I did exactly what Dr. Van Tharp recommended. I modeled a system that already worked.
Instead of trying to reinvent trading and spending years trying to figure out the markets, I modeled a proven system. In my case, that was CANSLIM.
Once you start with something that already has an edge, the goal shifts. You are no longer guessing. You are proving positive expectancy. You are learning consistency. You are building skill within a framework that has already stood the test of time.
Only after that do small adjustments make sense.
That is how a system becomes personal. Not by guessing. Not by shortcuts. By first getting results.
This is exactly how many great traders developed.
William O’Neil learned from Jesse Livermore, Nicolas Darvas, and Gerald Loeb. Later, traders like Mark Minervini, David Ryan, Dan Zanger, and many other Investing Champions followed the same core principles. Over time, they drifted from doing things exactly like O’Neil.
That part matters.
They did not drift first. They learned first. They proved results first. Then they adapted.
There is a proven system for you to model. You do not need to waste countless years losing money trying to invent one from scratch. That painful path is not a requirement.
Dr. Van Tharp put it perfectly:
“Right now, I consider myself to be an expert modeler. By that, I mean that if someone can do something well, then I can figure out how they do it and teach those skills to anyone else.”
That is the real advantage beginners have, if they choose to use it.
Model what works. Prove consistency. Then make it your own.
