Pros: Raw, unfiltered, authentic. You see what Gann actually wrote. Cons: Almost impossible to decipher alone. Gann used "lawyer language" and hid the math inside parables. A raw 1927 PDF is useless without a modern interpreter.

Squaring Price and Time: Finding the mathematical point where price and time are equal to predict trend changes.

Time Cycles: Analyzing historical cycles (e.g., 30, 45, 90, 144 days or 10–20 years) to forecast future trends. Where to Find Official & Modern Courses

But ask yourself: If his methods were completely worthless, why are hedge fund quants still studying time/price geometry 80 years later?

• Practical use: Finding price targets. If a stock is trading at $54 and breaks resistance, the Square of 9 predicts the next stop is $61, then $72.
• Cardinal Cross vs. Ordinal Cross: Understanding the difference between 90-degree increments and 45-degree increments.
• What a good course teaches: How to overlay a stock's price directly onto the Square of 9 to calculate "Gann support."
