Using “import wizard” to import data, there are just 12 columns. When needs add more columns,how to do it? Thanks!
I am yet to see a single example of data file with OHLC quotations that really needs more than 12 columns, but if you really have one, you can simply type desired format using $FORMAT command in the “Additional commands” field in the wizard. Anything what you type there would override any UI selections.
