BUG? ObjectsDeleteAll - wrong parameters count

[Dimitrios Vezeris]

Hello MQL5 community,

According to the ObjectsDeleteAll

int  ObjectsDeleteAll(
   long           chart_id,   // chart ID
   const string     prefix,   // prefix in object name
   int       sub_window=-1,   // window index
   int      object_type=-1    // object type
   );

when I can give a command such as:

ObjectsDeleteAll(0,label,0,OBJ_TREND);

should delete from chart=0, from indicator window=0, Trend Lines that have the prefix=label.

But the compiler returns the error wrong parameters count.

The MQL5 MetaEditor recognizes only 3 parameters version

int  ObjectsDeleteAll(
   long  chart_id,           // chart identifier
   int   sub_window=-1,      // window index
   int   type=-1             // object type
   );

and not the 4 parameters.

I'm using MetaEditor V5 build 1150 22 May 2015

Is MQL5 ObjectsDeleteAll documentation fake/buggy?
Is MQL5 MetaEditor outdated?

Looking forward for your responses!

Update your MetaEditor version, this new ObjectsDeleteAll() version was introduced in June, after build 1150.

Download and install MT4, then copy and paste Metaeditor.exe to your MT5 folder.
