RIGHT?

Not quite. Read the article.

And for MT5 I have attached the script below. See what result you get in your example.

I'm writing an EA based on a zig zag indicator, but it won't even open a position, so I think it's because of a warning:

Here's the full EA code.

How do I get my EA to trade, please?

MqlTick last_tick;
//---
   if(SymbolInfoTick(Symbol(),last_tick))
     {
      Print(last_tick.time,": Bid = ",last_tick.bid,
            " Ask = ",last_tick.ask,"  Volume = ",last_tick.volume);
     }
   else Print("SymbolInfoTick() failed, error = ",GetLastError());
//---

TheMqlTick structurehas to be filled in first, then you can apply

Thank you, I will try to figure it out now.

Poll the buffer, for example like this

handle=iCustom(NULL,0,"Examples\\ZigZag",12,5,3);
   ArraySetAsSeries(buf,true);
   copy=CopyBuffer(handle,0,0,100,buf);
   for(int i=0;i<100;i++)
     {
      if(buf[i]!=EMPTY_VALUE)
        {
         wert=buf[i];
         break;
        }
     }

Gentlemen!

I've been trying to build a bollinger robot for the second night. I figured out how to read prices from a chart, but I don't know how to build a bollinger indicator and get its values.

I found this indicator description in my manual https://www.mql5.com/ru/docs/indicators/ibands

iBands

It returns the handle of the Bollinger Bands® indicator.

Honestly, I don't understand it at all! The example below is three pages long, I got lost on the first page... Is it really necessary to bother to run such an indicator? Is it possible to read indicator values from a chart like in QuickBooks or should I first program this indicator myself?

It all looks so frightening!

Can you tell me how to interact with the indicators? How do I run bollinger and read its values?

And a second question right away.

I'm programming and learning the language at night and the exchange is already down. Is there any way to test my code at night, maybe there is some kind of tick generator in MT5?

Use strategy tester.

Thanks for the tester!

The question remains, how do you create and read indicators?
