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).
