Let's consider an example of automatic import of ticks. In the ticks.csv file, each trade is written as a line like GAZP,TQBR,20250401,128.58,74,10:00:02.000000: instrument, board, date, price, volume and time.

  1. With the magnifier button in the Settings row, open the import settings window.
  2. Select the Ticks data type and specify the path to the file in the File name field.
  3. Add the Time field to the S# fields: the required fields - instrument, board, date, price and volume - are already in the order in which the columns go in the file, and the time is added after them. Click OK.
  4. Enable the task with the Enabled switch and start the import with the Start button. Import (auto) task started
