For the application to work correctly, your CSV file has to include at least these columns with requirements:

• index (number, starting at 0 and incrementing by 1)
• timestamp (number, UNIX timestamp)
• open (number)
• high (number)
• low (number)
• close (number)

Optionally you can add:

• label (string)

ATTENTION! Order of the columns doesn't matter but order of the rows does: rows have to be sorted ascendingly index column.
