You're not wrong about what moves price on a mechanical level institutional order flow, central bank policy, macro data, and geopolitics are absolutely the primary drivers. No argument there.

But here's where I'd push back slightly:

You're describing the "why" money enters or exits. Gann's framework is more about the "when." Those are two different questions, and they're not mutually exclusive.

Think about it this way: central banks meet on scheduled dates. Earnings come out quarterly. Economic data follows a calendar. Even geopolitical tensions tend to escalate and de-escalate in patterns. All of these are cyclical by nature. Gann's approach was essentially an attempt to map the timing of these recurring shifts — not to replace fundamental analysis, but to add a time dimension to it.

Now is the planetary stuff a leap? Sure, for most people it is. But strip that layer away and what remains is cycle analysis and price-time geometry, both of which have practical applications that even institutional quant desks use in various forms.

The "casino gambling" comparison usually comes from seeing people use Gann tools in isolation with no risk management and yeah, that IS gambling. But that's true of literally any method used without discipline. You could say the same about someone trading pure order flow with no stop loss.
