Alexey Viktorov:

So limit it to the middle. Who forbids it?

If he is not male, then apparently PMS syndrome forbids reading and asking adequate questions, so far only squealing let me... I really want it this way and not that way...

ZS: I'm on 4 forums, if possible, I do about 20 free MT4 jobs a month, and about 10 orders for individual TK, but regularly every 1.5-2 months a fairy tale character appears who'll blow my mind because he doesn't need to understand MT4 or do a specific task under the order ... He just needs to make someone's head spin, that's his job...

I would give Artem a monument in his lifetime for his patience in dealing with such characters in such a long time.

Alexey Viktorov:

It's very easy to do.

Option 1 is to use your brain.

If you can't do it, you can use option 2.

Without fussing and without insulting the developers and forum users in particular, ask for help on the forum.

Otherwise you will be sent to the . mail.

I know how to get around this "feature".

Unlike the "respectable people" of this forum I will not make a secret out of it.

This way looks like this:

If you fill the remainder of the array we are not interested in with the maximum value, then the indicators stop drawing lines.

This is exactly the "idiotic" solution of this problem we see in standard MT4 indicators (for example, SMA, EMA, SMMA and others).

But, you must agree, this is complete idiocy. And I suspect that precisely because of this idiocy there is not a single word about this way of "solving" this problem in the description.

Maybe I'm wrong, but I haven't found any other way in the standard indicators.

[Artyom Trishkin]

Alexey Viktorov:

Exactly like this. You open a new account and transfer money from the old account to the new account by internal transfer with absolutely no fees.

I don't get it at all. Alexey, how do you even know what you are talking about? What does it have to do with 8 indicator buffers that some translator can't translate? I don't know...

You probably need a rest.

I don't understand anything at all. Alexei, how do you even know what we're talking about? What does it have to do with 8 indicator buffers that some translator can't translate? It's hard to understand...

Artyom, you're a programmer... M. Botvinnik once said that a computer is an idiot. Hence, every programmer knows how to talk to an idiot.

I've already read about 8 or 512 buffers before, and this text was about the complaint about the broker refusing to migrate the account from MT4 to MT5.

Igor Makanu:

I would give a monument to Artem in his lifetime for his patience in dealing with such characters.

I already have...

[Vasilii Goncharov]

advise what should be added to the court so that the indicator works every second instead of every tick?

#property indicator_chart_window

#property indicator_buffers 1

#property indicator_color1 Red

#property strict

double buffer[];

void init()

{

SetIndexBuffer(0,buffer);

SetIndexStyle(0,STYLE_SOLID);

}

void start ()

{

double vbid_1 = MarketInfo("USDRUB",MODE_BID);

double vbid_2 = MarketInfo("EURUSD",MODE_BID);

double a = vbid_1;

double b = vbid_2;

double x = a / b ;

buffer[0] = x;

Comment (x);

}

What do I need to add to the court to make the indicator work every second instead of every tick?

You need to readhttps://docs.mql4.com/ru/basis/function/events

and write your event handlerOnTimer()
