Slawa and all,
After I'm attaching script to chart;
I have this message: Error:
Cannot load external expert 'stdlib'.
What I have to do?
Thanks
Vlad
 
What script are you trying to load? Without this information it is hard to assist you.
 
Vlad, You need to compile stdlib.mq4. It should be in the experts/libraries directory
