Trends/Fibonacci and harmonic patterns

Fibonacci time zones

Vertical lines spaced by Fibonacci numbers of bars from a starting point, to see whether turns happen near them.

Illustration of the Fibonacci time zones shape. It is a sketch, not real price data.

What it shows

Time zones are vertical lines placed 1, 2, 3, 5, 8, 13, 21, 34 and 55 bars after a chosen start bar. The spacing gets wider with each line.

They are a way of asking whether turning points line up with the sequence. There is little evidence that they do, but the tool is common on charting platforms.

How we find it

The same code that draws it on your chart follows these steps, with the same result every time.

Pick a start bar: the most recent major swing low or high.
Draw vertical lines at 1, 2, 3, 5, 8, 13, 21, 34, 55 bars after it.
Count how many swing points fall within 2 bars of a line.
Show the counts.

Starting values: Numbers 1, 2, 3, 5, 8, 13, 21, 34, 55; Hit distance 2 bars. These are proposed and will be tuned on real price data before launch.

How to read it

Each cyan line is a Fibonacci number of bars from the start.
A swing point near a line counts as a hit.
The ratio of hits to swing points is shown.

Status labels you may see

Label	What it means
Next zone ahead	The next line is in the future.
On a zone	The last bar is within 2 bars of a line.

What cancels it

Nothing cancels it. The lines are redrawn if the start bar changes.

What traders check next

How many swing points lined up compared with chance.
Whether the start bar is a clear turning point.
Whether other tools show a turn around the same date.

Limits

Hits are easy to find by chance, because the lines are dense at the start.
The result depends on the start bar.
There is limited evidence that time zones work.

Questions

Why vertical lines?

They mark time instead of price.

Does it work?

We show it because it is common. We make no claim that it works.
