Alert: Error copying Bollinger Bands indicator Buffers - error:4807!!

Hi, so i was about to test my EA and I had this error "Alert: Error copying Bollinger Bands indicator Buffers - error:4807!!" What am I doing wrong...

Hi.. been getting this error on mt5 cant get it working

searched for many ERROR 4807 solution..cant get a solution "code"

played with it for while still cant get it working

Thanks..

Why not add a Print() statement:

   IndicatorFileName = GetRelativeProgramPath();;
   Print (IndicatorFileName);

To verify whether you are sending a valid indicator name to iCustom()?

2020.03.20 07:45:31.273 tryingtoconvert(GBPUSD,M5)
only this nothing else,

actually am trying to learn and master converting any mt4 indicator.. to mt5.. am only successful in converting one from mq4-mq5 and one from mq5-mq4

without property strict

IndicatorFileName = WindowExpertName();

with property strict WidowsExpertName() is not working

unless this is used

IndicatorFileName = GetRelativeProgramPath()

string GetRelativeProgramPath()

  {

   int pos2;

//--- get the absolute path to the application

   string path=MQLInfoString(MQL_PROGRAM_PATH);

//--- find the position of "\MQL4\" substring

   int    pos =StringFind(path,"\\MQL4\\");

//--- substring not found - error

   if(pos<0)

      return(NULL);

//--- skip "\MQL4" directory

   pos+=5;

//--- skip extra '\' symbols

   while(StringGetCharacter(path,pos+1)=='\\')

      pos++;

//--- if this is a resource, return the path relative to MQL5 directory

   if(StringFind(path,"::",pos)>=0)

      return(StringSubstr(path,pos));

//--- find a separator for the first MQL4 subdirectory (for example, MQL4\Indicators)

//--- if not found, return the path relative to MQL4 directory

   if((pos2=StringFind(path,"\\",pos+1))<0)

      return(StringSubstr(path,pos));

//--- return the path relative to the subdirectory (for example, MQL4\Indicators)

   return(StringSubstr(path,pos2+1));

  }

Thanks a lot for your feedback
