Hi
i exported tick data from 2010/01/01 till 2016/01/01 to fxt file, already i want to export tick data from 2016/01/01 till 2016/05/1 and i want to append this fxt file to previous fxt file (from 2010/01/01 till 2016/01/01), what must i do? because exporting again from 2010/01/01 till 2016/05/01 will take more time
thanks
