You Don’t Need Your Own Trading System Yet
I received a few comments from people who thought this contradicted something I have said before: every trader eventually needs to find their own way.
It does not.
What I am saying is that beginners can find enormous success by first learning and following someone else’s proven system as closely as possible.
Look at David Ryan.
Ryan learned directly from William O’Neil, worked as his assistant, and achieved extraordinary success applying O’Neil’s methodology. Decades later, Ryan said:
“I have never really deviated from the basic high-growth stock approach I’ve used since working at William O’Neil & Co.”
That is important because developing a completely original trading style is not a requirement.
Some traders eventually branch off, make adjustments, and develop a style that becomes distinctly their own. Others may continue trading the same proven methodology for their entire careers.
Both paths are legitimate.
The key distinction is that successful traders usually do not begin by changing rules they barely understand.
They first learn the system. They follow it. They gain experience across different market environments. They study their trades and understand why the rules exist.
Only then are they qualified to decide whether a change is actually an improvement.
Beginners often reverse that process.
They start with a proven strategy, immediately alter the entries, exits, filters, position sizing, and risk rules, and then blame the original system when their modified version fails.
They believe they are expressing their individual trading style. In reality, they may be removing the very components that gave the strategy positive expectancy.
There is nothing wrong with adapting a system, but every meaningful change creates a new version of that system, and that new version must be tested and validated.
You need to know whether it works over a meaningful sample of trades, across different market environments, and after accounting for losses, drawdowns, and execution mistakes.
Until you have that evidence, the modification is not an improvement. It is an unproven idea.
Many traders learned that lesson by blowing up accounts, suffering years of unnecessary losses, or abandoning strategies that would have worked if they had simply followed the rules.
You do not have to learn that lesson with your entire account.
Test your changes with small amounts of capital. Track the results. Compare them against the original system. Prove that the adjustment improves expectancy rather than merely making the strategy feel more comfortable.
Yes, every trader may eventually find their own way.
But that does not mean every trader must invent a new methodology.
For many traders, the smarter path is to first master a system that has already been proven to work.
Saying, “I trade my own way,” does not automatically make that way valid. A personal trading style is not a real edge simply because it feels natural or makes sense to you. Unless you have tracked it over a meaningful sample of trades, measured its expectancy, studied its drawdowns, and verified that it works across different market environments, you are not trading a proven personal system. You are trading an untested idea.
You may eventually adapt a proven methodology, or you may never need to, but do not use “finding your own way” to justify ignoring proven rules without doing the work required to prove that your changes actually work.
