Examples

Generate a Kagi Chart for a Data Series for a Stock

Load the file SimulatedStock.mat, which provides a timetable (TMW) for financial data for TMW stock. This Kagi chart is for closing prices of the stock TMW for the most recent 21 days. Note that the variable name of asset price is be renamed to 'Price' (case insensitive).

load SimulatedStock.mat
TMW.Properties.VariableNames{'Close'} = 'Price';
kagi(TMW(end-20:end,:))
title('Kagi Chart for TMW')

Input Arguments

Data — Data for a series of prices

matrix | table | timetable

Data for a series of prices, specified as a matrix, table, or timetable. Timetables and tables with M rows must contain a variable named 'Price' (case insensitive).

Data Types: double | table | timetable

ax — Valid axis object

current axes (ax = gca) (default) | axes object

(Optional) Valid axis object, specified as an axes object. The kagi plot is created in the axes specified by ax instead of in the current axes (ax = gca). The option ax can precede any of the input argument combinations.

Data Types: object

More About

Kagi Chart

A Kagi chart represents price movements of an asset over time, focusing on the direction of price rather than the time intervals.

Kagi charts consist of a series of vertical lines that change direction based on price movements. The lines are drawn based on price changes and not on time intervals. The chart starts with a vertical line that represents the initial price level. If the price rises by a specified amount (called the "reversal amount"), a new line is drawn in the upward direction. Conversely, if the price falls by the same reversal amount, a line is drawn downward. The reversal amount is a key parameter in Kagi charts. It determines how much the price must change before a new line is drawn. This helps filter out minor price fluctuations and focuses on significant price movements.

Version History

Introduced in R2008a

R2022b: Support for negative price data

The Data input accepts negative prices.

R2018a: Support for matrix, time, or timetable input for data

kagi accepts Data input as a matrix, timetable, or table.

The syntax for kagi has changed. Previously, when using table input, the first column of dates could be serial date numbers, date character vectors, or datetime arrays, and you were required to have specific number of columns.

When using table input, the new syntax for kagi supports:

• No need for time information. If you want to pass in date information, use timetable input.

• No requirement of specific number of columns. However, you must provide valid column names. kagi must contain a column named ‘price’ (case insensitive).
