strange.
checked, it shows everything.
maybe the chart needs to be compressed vertically, if the channel is wide, it may not be visible when zoomed in.

Something came up after adjusting the parameters. Only a very narrow range fits the EA's conditions. A step to the left, a step to the right - nothing. And these conditions do not fit the definition of a flat. I am getting a flat at 100 points in 4 digits. And everything is shown accurately.

I altered it a bit - I tried to understand it. But it works that way. I used H1. It is bad that I failed to show it on other TFs due to parameter selection. For example, on 5 and 15 minutes. - One could suggest that it would be possible to achieve a flat using those TFs. (If someone with a more experienced viewpoint gives some ideas or points out the errors).

I have not noticed any problems with the rendering.

In your indicator, as in the vast majority, what is drawn is what it used to be; that's normal for the indicator writing template. But what is going on now (as you said - on the current bar) do not get into conditions of this indicator. Therefore, there is no problem at the current bar.

What you have in this indicator, as well as the vast majority, is rendering what was once; which for the indicator writing template is normal. But what is going on now (as you said - on the current bar) does not fit into this indicator's conditions. Therefore, there is no problem on the current bar.


ParameterPauseBar is the minimum distance separating one channel from another, in your edition this parameter should be greater than 5, then it is drawn at different other parameters.
But the problem with rendering with new bars remains.

To be honest, I don't understand the logic of your indicator's work (though I do understand its essence). But...

Look - the problem lies exactly in this block:

        if(FirstChanel) { Up[i]   = high;   Down[i] = low;  }                             // отрисовка первоначального отправного канала
        if(up_chanel)   { Up[i]   = high;   UpSupport[i]      = high - Channel*Point; }   // отрисовка канала тренда вверх
        if(dn_chanel)   { Down[i] = low;    DownResistance[i] = low  + Channel*Point; }   // отрисовка канала тренда вниз

At some point values are not written to buffers and therefore they are assigned a value of "zero". Hence the sticks down - to zero. How to build logic and what to add - I can't understand. But the data is not written obviously because you have flags, including the parameter

DrawChannel=false;

Therefore, the values don't get to be assigned to the buffers. - You need to play around with this somehow.

I see, so it's a matter of logic. I'll think about it.
Thank you for your help.

P.S.
Check if everything is rendered well on your history with increasing PauseBar parameter with another set of other parameters, or is there a problem with it too?

 
how do I view and display the extended ascicode table symbol?

P.S.
Do you at least check if everything is displayed correctly on your history when increasing the PauseBar parameter with a different set of other parameters, or is there a problem with it too?

I checked with increasing PauseBar and got these sticks at 1 and 5 min. But I can't figure out how to bypass them correctly. I understand that you need to write probably (but not obviously) if the value 

DrawChannel=false;

в

if(dn_chanel)   { Down[i] = low;    DownResistance[i] = low  + Channel*Point; }   // отрисовка канала тренда вниз

the value of the previous bars - something like this:

if(dn_chanel)   { Down[i] = Down[i+1];    DownResistance[i] = DownResistance[i+1]; }   // отрисовка канала тренда вниз
But when I try to do it, my whole indicator "moves" - because I don't understand the logic and I don't understand where to put it and under what conditions.

This is called ANSI.

For the first time on the forum, I decided to ask a question that interests me - is it possible to make changes in the terminal to insert my comment (1 or more times) when a position is already open? not immediately when you open a comment. but when you have already opened it - so that the current comment appears?
 
Please advise how to solve the problem: The same EA is on several charts, a signal to open an order appears on two charts at the same time, for example. However, we need the second order not to open. The EA has a check for an open order but it does not help because the first EA has probably open an order and the second one also sends a request to open an order. Are there any possible solutions?
