More About

Renko Chart

A Renko chart is a type of financial chart used in technical analysis to represent price movements of an asset without considering time intervals.

Instead of plotting price changes over time, Renko charts focus solely on significant price movements, filtering out minor fluctuations. This makes them particularly useful for identifying trends and reversals in the market.

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

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’ (case insensitive).
