Can't beat that.

Look for an error in .............

The problem is the same - after the calculation the number is much lower than the decimal point, so the indicator goes blank after such a section.
 
Can you advise which function or line in the code is responsible for call of expert's properties (with a window for entering parameters)? I noticed in some experts it is impossible to call this window when it works on a chart, i.e., you can see what parameters are set in the expert only at initial startup, then you can not see what is prescribed there from the chart.
 

Hi!

Can you tell me if there is an operator that can replace the calculation: = iHigh - iLow

to determine the height (length) of a particular bar in pips?

I really need it! )

No! :-)

When the Expert Advisor is running in the currency pair window, you'll see a smiley in the upper right corner. Just click on it and a window with input parameters will pop up.

The trick is that it doesn't work with all EAs. I want to know why. Below is a screenshot of how the properties window should be open (click on a chart with EAs-advisors>properties>Properties window pops up). The thing is that all normal EAs open (when market is moving too much, not at first, but after 3-4 times), but some EAs open properties window on 20th time (no reaction even after pressing the smiley face).I think it is very difficult to change parameters (or just look at them) to view chart of Expert Advisor every time, so I have to registered something in code.

 

There's a hell of a lot going on. The indicator draws, then it doesn't. I put the code you suggested below mine, although I wondered what the values were. I pulled the indicator onto the chart. It's got a red line on it!!!! It sure does!!! Yay !!!!! And there is a green line, even two, one is just vertical, amazingly, and most importantly there!!!! I have redlined your code, compiled it again, nothing changes.

I added a blue line!!! I compiled - there's a blue line too !!!!!! I changed the timeframe from H1 to M30 All the lines disappeared!!!!!! Yeah, yeah, just disappeared!!! I'm on M15, on H4, again on H1, there are no lines anywhere!!! Wow!!!

I removed the indicator from the chart and put it back on the chart - the devils still did not appear!!! What is it? Here's the chart, here's the indicator on it. Here's the indicator now.

I was getting out of the beginner's question due to the nioble movement that had begun. Of course, I understood what you meant to say - that the points should be filled with values in a row. Thank you very much for the suggestion!

MikeM:
I useDRAW_LINE. I have a misunderstandingwith DRAW_SECTION.

Thank you!!! I'll give it a try. Wait, what's there to try? Line is a solid line and it needs to be filled exactly element by element, but it's a totally different song - I already figured it out after 15 seconds.

If the properties window is not called during operation - then the Expert Advisor works in a looped mode
  
High1 = iHigh (Symbol(), PERIOD_W1, 0); // максимум этой недели
Low1 = iLow (Symbol(), PERIOD_W1, 0); // минимум этой недели

There is such a thing in the Expert Advisor, on the demo and on the real all is well, but I would like to run the code in the tester, but in the maximum time frame D1, how to write a function, if possible, that would make the maximum and minimum data of the current week were still in the tester?
