Trends/Reversal patterns

V bottom

A sharp fall followed by an equally sharp rise, so the low is a single narrow point.

Reversal patternsBest on 3M, 6M, 1YAlso called spike low, V-shaped recovery

Illustration of the V bottom shape. It is a sketch, not real price data.

What it shows

A V bottom has no pause at the low. Price drops quickly, hits a low, and rises just as quickly. The chart makes the letter V.

Our code finds it by measuring how fast price fell and rose around a swing low.

How we find it

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

Find a swing low.
Require a fall of at least 15% in the 10 bars before it.
Require a rise of at least 15% in the 10 bars after it.
Mark the low as the bottom of the V.

Starting values: Fall before the low 15% in 10 bars; Rise after the low 15% in 10 bars. These are proposed and will be tuned on real price data before launch.

How to read it

The teal dot is the lowest point.
Steep sides mean fast moves in each direction.
Both sides are of similar length and slope.
