Crontab - is a part of any *NIX OS. It runs some programs at defined time. Smart Trade Script uses it to collect and optimize stats

If you see notine “check crontab” in Main tab that means you have to check crontab . It should be like

 copy from here: */1 * * * * cd /path_to_scj/bin/; env HTTP_HOST=yourdomain.com /path_to_php/php -q cron.php

If you use internal thumbs rotation engine also all this

 copy from here: */1 * * * * cd /path_to_scj/bin/; env HTTP_HOST=yourdomain.com /path_to_php/php -q rot.php

it's a good idea to spread load across a minute. Create file scj.sh and add there all tasks ( without * and with & at the end ) for example

  cd /path_to_scj/bin/; env HTTP_HOST=yourdomain.com /path_to_php/php -q cron.php &
  sleep 2
  cd /path_to_scj2/bin/; env HTTP_HOST=yourdomain2.com /path_to_php/php -q cron.php &

Change sleeptime so all of your tasks are executed within 1 minute, it's important.

and add this file to crontab

*/1 * * * * cd /path_to_sh_file/ ; sh scj.sh

NOTE total amount of sleep seconds should be less then 59, if you have more lines - add sleeps each 2 lines for example.
