Alexey Viktorov:

bool  ChartGetInteger( 
   long    chart_id,        // идентификатор графика 
   int     prop_id,         // идентификатор свойства 
   int     sub_window,      // номер подокна 
   long&   long_var         // сюда примем значение свойства 
   );

with identifiers CHART_PRICE_MIN and CHART_PRICE_MAX

CHART_FIXED_MAX	Chart fixed maximum	double
CHART_FIXED_MIN	Chart fixed minimum	double

How were you going to get the values ofdouble, with

bool ChartGetInteger

or

long ChartGetInteger

you are a documentation expert?

You also advised CHART_PRICE_MINand CHART_PRICE_MAX to get the values of min and max oscillator, which have their own data. :) Well... Well, if it isn't the expert in MQL documentation... :)

We study the documentation not attentively. But there is no understanding. Not because of this, but because of poor knowledge of the concept of programming and MQL in particular!

Actually yes, not a lot wrong, but I figured it out,

ChartGetDouble(0,CHART_PRICE_MIN,1));

ChartGetDouble(0,CHART_PRICE_MAX,1));

so it does what I need.

Now a new question, how to visualize the indicator out of the Expert Advisor? I.e. with this variant, I have to load the indicator manually, or the result shows 0.

Actually yes, not much is wrong, but I figured it out,

ChartGetDouble(0,CHART_PRICE_MIN,1));

ChartGetDouble(0,CHART_PRICE_MAX,1));

does what it should.

And you're trying to get min and max values in the oscillator, not in the chart...? :)

Why write, that you need oscillator's values and not the chart's, if your problem definition changesso sharply?

I also gave you the code for the oscillator. It works very well. Foolishness...

Good day to you! I paid my EA rent but the payment was frozen for 7 days, can you explain what this is about?

Everything is written

I got the values I needed using the method above. But the thing is that these values can only be obtained when I manually load them on the indicator chart (in the tester in particular). I don't know how to load not only the indicator buffer, but also how to visualize it from the EA.

TesterHideIndicators(false);

Only the indicator has to be created programmatically.

Although created indicators are shown in the Expert Advisor at https://www.mql5.com/ru/docs/common/testerhideindicators anyway.

[Anatoliy Markov]

TesterHideIndicators(false);

Alas, it doesn't work. The indicators are only shown when stopped.

And there is an interesting possibility to hide indicators selectively.

You can also write an oscillator visualiser on Canva. I gave you the basisat https://www.mql5.com/ru/forum/160683/page1569#comment_23835904.

Thank you again for your input, but it was the vertical visual scale of my oscillator that I wanted. I got what I needed. But the subbokno (visualisation of the indicator) needs to be called manually, that's the bad thing. I do not know how to visualize the indicator from the Expert Advisor. I.e., when I install the Expert Advisor on a chart, the indicator is automatically displayed.
