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 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).
