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.
