the hell if I know)

Delete list item 0 - 1 becomes 0, item 2 becomes 1, etc.

Delete list item 1 - 2 becomes 1, etc.

etc.

With direct loop it turns out that objects are deleted one by one.

Yes, I put the second option to get and delete 0 index:

s_ObjectName = ObjectName(i_chart_id,0,i_nwin,i_type);

In the hope that someone will always be at 0 index.

In short, you're right with it, it worked, and thank God!

Without filter, deleting object 0 in the list of objects in the loop should theoretically delete everything.
But it's not interesting without filter) and you can delete everything with ObjectsDeleteAll() function.

Thanks a lot!!!!!!!! I tried 2012.05.17 10:24:14 ZZZ_Setka_Save Invalid EX5 file
came up with this

Prev[][5];

ArrayResize(Prev,Bar_Istory);

I tried ArrayInitialize(Prev,0) before;

replaced by ZeroMemory(Prev) ; the result is ZZZ_Setka_Save Invalid EX5 file

What was it? // if it's not a secret.

I've also noticed that zeromemory fails in some (not all) usage contexts.

Been too lazy to catch the bug and send it to you.
