renko

renko is updated to accept 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 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 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).
