[Alexander Chertnik]

hi everybody.

the code is working but the value returns as 0.

if anyone could help. thank you.

Graphical objects do not work during optimisations.

Instead, write your code not to depend on graphical objects for data. Use variables (they are way faster).

Only use graphical objects for display purposes if really needed. Have an option to enable them or not for the user, but don't depend on them for the logic execution.

Graphical Objects in Testing

During visualization, the Expert Advisor interacts with a real chart. In case there is no visualization, the Expert Advisor works with a "virtual" chart that is not displayed. The former case has some peculiarities. During optimization, working with graphical objects is not supported.
