W.D. Gann traded commodities and stocks in the first half of the twentieth century and left behind a body of methods — angles, squares, cycles — presented as a hidden geometry linking price, time and natural law. He is either a forgotten genius or the market’s most successful myth, depending on who is selling the course. This lesson takes him seriously enough to say clearly which.
What the tools actually are
- Gann angles — trendlines drawn at fixed price-per-time rates from a high or low; the 1×1 (45°) is the "balanced" trend, with steeper and shallower angles marking stronger and weaker ones.
- The square of nine — a spiral of numbers used to relate prices and dates by their angular position on the spiral.
- Time cycles — anniversaries of past highs and lows (the 30-, 60-, 90-, 360-day counts) expected to mark future turns.
Where the objectivity leaks out
The 1×1 angle rises "one unit of price per one unit of time" — but what is one unit of price on a stock trading at ₹47 versus one at ₹4,700? That scaling is a choice the analyst makes, and different choices produce different angles on the identical chart. A tool whose output depends on a free parameter you tune until it looks right is not measuring the market; it is measuring your tuning.
The one idea worth keeping
Strip away the mysticism and one modest, sensible notion remains: time matters, not just price. A stock that has gone nowhere for two years is in a different situation from one that reached the same price yesterday, and marking the calendar anniversaries of major turns as dates to pay attention — not to obey — is a harmless way to stay alert. That is a footnote to Gann, not a system, and it needs none of the geometry to be useful.
Why does the square of nine so often appear to "work" when you look back at a chart?
Gann kehta hai price aur time ek fixed geometry mein chalte hain — angles, square of nine, cycles. Sunne mein rahasyamayi, par ek dikkat: 1x1 angle "ek price unit per time" pe banta hai — par ₹47 wale stock pe ek unit kya, ₹4,700 pe kya? Woh scaling aap khud chunte ho, toh same chart pe alag-alag angle. Itni saari lines aur numbers daalo ki kisi bhi turn ke paas kuch na kuch fit ho hi jaata hai — yeh prediction nahi, hindsight hai. Gann ki "crores" bhi kabhi verify nahi hui, estate mamooli thi. Bas ek kaam ki baat rakho: time bhi maayne rakhta hai, sirf price nahi — baaki geometry chhod do.
- Gann claims price and time move in fixed geometric proportion — a claim that resists any clean test.
- The angles depend on a price-scaling choice, so the same chart yields different lines.
- Overlaid tools always fit in hindsight; the honest test is a level and date stated in advance.
- Gann’s legendary wealth is unverified and his estate was modest — ask where the proof is.
- Keep only the modest idea that time, not just price, matters — and drop the geometry.

Common questions
Short, direct answers to what people ask about this topic.
- what is gann theory in stock market
- Gann theory is a set of trading techniques from the early-1900s trader W.D. Gann, built on the idea that price and time move in fixed geometric and numerical proportions — most famously the 45-degree "1×1" angle and the spiral of numbers called the square of nine. It claims these tools forecast both the level and the date of future turns. The methods are elaborate and have a devoted following, but no independent test has shown they predict prices better than chance once you account for how flexibly they are applied.
- what is a gann angle
- A Gann angle is a trendline drawn at a fixed rate of price per unit of time from a significant high or low — the central one, the 1×1, rises one price unit per one time unit and is meant to represent a balanced trend. Steeper angles (2×1, 4×1) mark stronger trends and shallower ones (1×2, 1×4) weaker ones. The practical difficulty is that "one price unit" is a scaling choice the analyst makes, so the same chart yields different angles depending on that choice — which is where objectivity leaks away.
- does gann theory actually work
- There is no credible evidence that Gann’s forecasting methods work, and Gann’s own legendary returns have never been independently verified — the often-quoted fortune is not supported by his estate, which was modest. The methods survive because they are so flexible that a skilled user can always find an angle, a square or a cycle that fits after the fact. Treat Gann as market history and a lesson in unfalsifiable systems, not as a forecasting tool to risk money on.
- what is the square of nine in gann
- The square of nine is a spiral of numbers, starting from a centre and winding outward, that Gann used to relate prices and dates by their position on the spiral — numbers a quarter or a full turn apart are treated as significant support, resistance or timing points. It can look uncannily accurate in hindsight because a dense spiral of numbers will always sit near any price you choose. That density is exactly why it fails as a forward test: it can hit almost anything, so hitting something proves nothing.
