Yep, so the newly created advisers by the master don't work at all!?

That's the thing, I recompiled it!

My fault.

uncleVic:
My bad.

Good!

[Владимир]

To uncleVic.

I would like to revisit the possibility of enabling automatic multicurrency generation in the Wizard. The main reason for not doing it was the complication of Wizard's menu. But the complication comes to adding only one menu - the list of currency pairs for concurrent operation, if we agree, of course, that all input data for these pairs will be common. This is quite acceptable according to my experience with multicurrency tools. The implementation mechanism won't be difficult for you either. In essence it comes down to mechanical multiplication of a stretch of code with small inclusions for each symbol.

That is, the wizard menu and implementation are not much more complicated, but we get a more versatile wizard that allows you to implement multiple strategies almost immediately and in multicurrency mode.

I am attaching my variant of the solution. It may be useful.

Hello moderator!

Thanks for the tip. Trying to figure it out. There's a question here about the program code:

As I understand it, the settings (i.e. input parameters) of the custom SAR indicator are described here. The first three (from 0 to 2) are clear. Where does the fourth (applied price) come from? It is not present in the custom SAR indicator itself. Please explain this block in details! Perhaps this is the most difficult part of this whole redesign (customization) of the custom indicator. Thank you in advance!

//--- prepare indicator parameters
   MqlParam CustomSAR_prop[];
   ArrayResize(CustomSAR_prop,4);
//--- indicator file
   CustomSAR_prop[0].type=TYPE_STRING;
   CustomSAR_prop[0].string_value="Examples\\ParabolicSAR";
//--- SAR step
   CustomSAR_prop[1].type=TYPE_DOUBLE;
   CustomSAR_prop[1].double_value=m_step;
//--- SAR maximum
   CustomSAR_prop[2].type=TYPE_DOUBLE;
   CustomSAR_prop[2].double_value=m_maximum;
//--- applied price
   CustomSAR_prop[3].type=TYPE_INT;
   CustomSAR_prop[3].integer_value=PRICE_CLOSE;
//--- initialize object
   if(!m_sar.Create(m_symbol.Name(),m_period,IND_CUSTOM,4,CustomSAR_prop))
     {
      printf(__FUNCTION__+": error initializing object");
      return(false);
     }
   m_sar.NumBuffers(1);
//--- ok
   return(true);
  }

Yes, you probably don't need it. I didn't write it.

[Igor Semyonov]

Then, if I may ask one more question about this code fragment:

m_sar.NumBuffers(1); - what is this operator for (where does it go) and why is there a 1 in brackets?

It sets the number of buffers of the user indicator (because their number is not known beforehand).

Thank you!

I managed to implement this idea completely! And based on a custom indicator of sufficient complexity. I will think that maybe I should try to write a corresponding article on this subject. There is nothing really complicated about it. :)
