Yedelkin:
In other words, do you want the moving averages to be calculated not from the EURUSD H1 chart data, but from the data from which the bars of the technical/user indicator are drawn?

yes, that is correct

[Yedelkin]

ilunga: yes, exactly so

Well, then it turns out that we must anyway pass to the technical indicator iMa the values of the indicator buffer of the predecessor indicator. If the predecessor indicator has several indicator buffers(for drawing bars), then, to specify a specific buffer, we must obtain its handle using iCustom. No other ideas yet.

I will implement it this way for now. There is an option "use data of the previous indicator" in the settings, I hoped to automate it

I can't immediately find the information in the Reference Manual, but it was said somewhere that "using the previous indicator's data" only transfers the data of the very first indicator buffer. That is, by specifying a handle, we are actually only pointing to the first buffer. It doesn't always suit...But, if the predecessor indicator has only one buffer (or if there is no need to specify other buffers), then, theoretically, we can try. Unfortunately, I never worked with technical (standard) indicators, therefore I can only guess.

I don't get it. I decided to make an analogue of Sleep() in indicator and solder it to Label (by pressing it to have a visual effect of pressing)

void InitClick(string Name)
{
   long CLR;
   uint mSecs=GetTickCount();
   uint Delay=100;
   CLR=ObjectGetInteger(0,Name,OBJPROP_COLOR);
   ObjectSetInteger(0,Name,OBJPROP_COLOR,clrSilver);
   //Comment("");
   do
   while (GetTickCount()-mSecs<Delay);
   //Comment("");
   ObjectSetInteger(0,Name,OBJPROP_COLOR,CLR);
}

It doesn't work at any value of Delay, so I have no option to change it very quickly.

If I uncomment strings, everything works. What's the problem?

ChartRedraw needs

Thank you

Doobjects like OBJPROP_COLOR have numeric equivalents (this was the case in MQL4, but it was in the help, not here)? (I would like to do enumeration in a loop)

another question: can I connect external libraries in MQL5 ? if so, is there any information about it?
