Renko
Description
Examples
Generate a Renko 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 example shows how to plot a Renko chart for the most recent 21 days. Note that the variable name of asset price is renamed to 'Price'
(case insensitive).
load SimulatedStock.mat TMW.Properties.VariableNames{'Close'} = 'Price'; renko(TMW(end-8:end,:),2) title('Renko 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.

Least price change value when adding a new box, specified as a scalar positive numeric value.
Data Types: double
ax
— Valid axis object
current axes (ax = gca
) (default) | axes object
(Optional) Valid axis object, specified as an axes object. The renko 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.

Output Arguments
h
— Graphic handle of the figure

Graphic handle of the figure, returned as a handle object.
Version History
Introduced in R2008aR2022b: Support for negative price data
The Data
input accepts negative prices.
R2018a: Support for matrix, time, or timetable input for data
renko
accepts Data
input as a matrix,
timetable
, or table
.
The syntax for renko
has changed. Previously, when using table
input, the first column of dates could be a datetime array, date character vectors,
or serial date numbers, and you were required to have specific number of
columns.
When using table input, the new syntax for renko
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.
renko
must contain a column named‘price’
