The MA is used in the EA, I need it for visualisation as well.

If you do not know when to open and close the order, then I want to be able to see it on the chart and know when the order triggers

Then the library will help. But it will only help with loading the indicator from the EA. The calculations are up to you as you do them.

See the library section " 7. FUNCTIONS FOR CONTROLLING MQL4 PROGRAMS".

I wanted to consolidate the issue with the transfer of parameters from the link.

To write a simple expert so to speak.

In the log, 0 is constantly being output. Why?

On the line:

void Test(double& a, double& b)

I didn't put "firstBarClosed" and "secondBarClosed" because these are formal parameters. This is already in the start function

if(a > 0)
   {
     Test(firstBarClosed, secondsBarClosed);
   }

New account made for metatrader! money loaded from Market trader! on the website in the account statement - there is money. I don't understand it at all. technical support is also in a stupor... Trying to understand it myself!


Some DCs require a copy of your passport or something similar... Try to open a demo account for the sake of interest.

Fixed the link. You should have figured it out yourself. It was a private link. You should have removed my.

how to make an indicator on a chart (line) in an EA

If you will run in the tester and check "Visualisation", the MA will automatically be displayed.
If you need to watch in the current mode, just put the MA on the chart with the parameters you have in the EA. They will not relate to each other, but it will be obvious
 
Arles:

Can you give me a hint? I am writing lines like this:

I want High to be counted by MA, not by price. This code doesn't work. I need something similar to iMAOnArray, only iHIGHOnArray. But as far as I know, there is no such thing. Help...


The question is not quite clear: "I want High not to be counted by price". High[] is a predefined value, we can't change it, maybe we want MA by price High ?

No, we want to know the maximum value of the MA itself for the period.
 
Arles:

No, you need to know the maximum value of the MA itself over the period.
Now I see. Most likely, we have to create an array for MA values and then a second array to store the max values, or a variable if only the last max value is needed.
