Can you tell me how to draw a square or rectangle without drawing it as a background, and draw it as a frame?

Thank you

In the list of object properties, set the rectangle property to be drawn as a background to false:

ObjectSet( string name, OBJPROP_BACK, false) ;

But the object will be drawn before the chart .

I apologise, perhaps for an unreasonable question...


I am a little slow with indicator buffers.... Or, I haven't quite figured out the indicator itself...


Could you please advise how to refer to BrainTrend2StopN indicator if possible?


I want to check if the opening of the current bar is higher/lower than the indicator values.

I access the indicator from the EA with string:


iCustom(NULL,0, "BrainTrend2StopN",CountBars, 1,0)

or

iCustom(NULL,0, "BrainTrend2StopN",CountBars, 0,0)

for zero and the first buffer respectively....

But, the Expert Advisor doesn't react to this string...


Many thanks in advance.

The Expert Advisor doesn't react to this string...

Note that you have 2 external parameters in your indicator:

extern int Simbol =119;

extern intBars=500;

you have to write them all in the iCustom:


iCustom(NULL,0,"BrainTrend2StopN", Simbol, CountBars, 0,0);

iCustom(NULL,0,"BrainTrend2StopN", Simbol, CountBars, 1,0);

Thank you very much. Corrected the code, now I pass both parameters, but unfortunately, when I call Alert with indicator buffer values, I get only zeros....


If you get a chance, can you tell me how to deal with it.

Try

Alert("Buy signal",
      "  ",
      DoubleToStr(iCustom(NULL,0,"BrainTrend1StopN", Simbol, CountBars, EnableAlerts, SignalID,1,0),8),
      "   ", 
      DoubleToStr(iCustom(NULL,0,"BrainTrend1StopN", Simbol, CountBars, EnableAlerts, SignalID,0,0),8)
      );
 
Please help me, gentlemen programmers. I have been struggling with this for a week, but nothing works, because I have no idea how to program. Can you write an indicator that crosses two HMAs and has pointers in the form of arrows?

Can anyone tell me what my mistake is?

First, put the code into a readable form, using tabs indicating the nesting level and the SRC button

 

Hello.


Please help me to understand the information function from the tutorial https://book.mql4.com/ru/build/info I have not understood for a week, why no signals from it appear? I took the Expert Advisor exactly from the tutorial, the inform is included inside.


Do I need to add an indicator to my chart? What should I use to fill it? The example has an empty indicator and I want to fill it with whatever I want... How to make it display signals of Inform() function?

 

Looks like a week for us newbies is the deadline after which we go to you pros))))
