Not spirals but geometric nonetheless:-

When I was a child there was a mathematician in my home town that lost his marbles, he used to draw spirals all over the city connecting things with it. He sprayed the city for months with all sort of spirals and comments underneath them.

So every time I see these spirals I think, "ok... another one. First sign of madness."

Was his name gaudi?

LOL= good points
WE used to draw those spirals in geometry class\
they never looked as good as the silk based spirals in a spyder web trap.
I wonder if those spirals marked the $35 low in gold??
Trend lines work well especially those autodrawn that avoid trader bias. NOT that any trend line predicts, they dont.
But there is a good reason they call it weather forecasting, not weather prediction

THAT's logical\orange is in color family red=negative;
blue, is in green family, positive. Typical candle chart colors
[I also use a greenish yellow hi lighter just to hi light]

Gann is always interesting. Especially the connections to the Great Pyramid and the ratios contained therein. Currently doing a deeper dive on the various concepts. He doesn't mention his wheel of time much and more-so the Square of 9. Haven't quite figured out how he built the Square of 9.

Started with a simple multiplication table and placed into quadrants to facilitate calculations of a Unit Circle.

I thought it the Square of 9 would be some derivative of that, but nothing popped out.

However, the Unit Circle got me to Fourier Transforms and their Inverses.

Which brought up this fascinating video of how Tides Cycles were analyzed, calculated and forecast.

I'm going experiment and pu an analog computer. Whether it has any practical application, idk.

Here's an OG Differential Analyzer

Logarithmic Spirals appear in nature and may be helpful to predict if a price bar is a potential turning point.

I represent them similar to the way in this book with a

• Center Point -- x,y coordinate
• First Point -- x,y coordinate
• Growth Rate (greater than one) -- how much the distance to the center is multiplied for each revolution added
• Direction -- counterclockwise or clockwise.

In each the following charts,

• The center point is a +
• Five Wave points defined similar to those in this post are squares
• Each bar is for a calendar day, and when the market is closed, the price is linearly interpolated from the previous market close to the next market open
• Prices are adjusted for splits and dividends, and the prices and times are scaled from 0 through 100 from the actual price and bar index values of the wave points
• The bar the most recent wave point was detected on has an X at the end
• The triangle at the end of a bar is the current bar to be checked. It will always be at or after the X. Bars after that show what happened next
• The dates on the X axis label are for the first wave point and the current bar
• The small diamonds are points on the spiral separated by one degree of arc. To keep the charts readable, the spirals are cut off if they go too much out of the chart time and price range

I wrote software to find a spiral that goes near the wave points. The code uses the scaled x,y coordinates of the wave points and no other market data to create the spirals. When the spiral also goes near the current bar, the current bar seems to often be at or near the next wave point.

Has anyone used logarithmic spirals to help with trading?

Does this book explore these particular fact about fibs?

"Interesting thing about fibs, the last digit of the first sixty in the sequence repeat every 60."

"Various groupings of adjacent above numbers have a symmetry with their opposites across the circle."

What I did is literally curve fitting, since it's trying to fit a curve to the wave points. I would also consider putting just about any markings on a price chart as curve fitting.


Speaking of spirals and madness here is a product with a feature that has its users fit artifacts to price charts like this.

That chart has four golden spirals (logarithmic spiral whose growth rate is =~ 1.618 for each 90 degrees of arc) and four lines that users would manually fit to the candlesticks!

Came across Michael Jenkins work (advocate of Gann), this particular form of analysis comes up, currently just skimming his works but looks substantial.
