The fourth forum for MT4 was not destroyed, but as a reference - General

Artyom Trishkin 2016.01.31 16:22 #14871

Aleksandr Novikov:

Will there be an answer, or will it go down in history as an uncomfortable question as usual?

Or is the administration only able to change the sequence of links in the top menu?

The fourth forum has long been unsupported, but as a reference material remains. At least this decision was voiced by the administration.

Aleksandr Novikov 2016.01.31 18:58 #14872

Alexey Kozitsyn:

Even though I'm not from the administration, you haven't answered my question either...

Yes, I logged into the forum under my account and what does that get you? Just satisfy your curiosity?

Artyom Trishkin:
The fourth forum hasn't been supported for a long time, but it was preserved as a reference material. At least this decision was voiced by the administration.

So they would have closed it and redirected everything to the mql5 forum. Why neuter it?

People continue to use it and communicate, which means it's needed and its functionality should be maintained!

So it turns out that, as always, the users and their opinion are ignored and everything is decided unilaterally.

How should I know, maybe you want to see an asterisk without logging into your account? Then it's logical that you won't see it there.

Aleksandr Novikov:

Yes, I logged into the forum under my account and what does that do for you? Will it just satisfy your curiosity?

So why not close it and redirect it to the mql5 forum? Why do you want to neuter it?

People are still using it and communicating, which means it's needed and its functionality should be maintained!

But it turns out that, as always, the users and their opinion are ignored and everything is decided unilaterally.

That's exactly why you were not asked about a year ago, when they made the decision to stop supporting the fourth forum. Precisely because there is a lot of useful information there, it was not destroyed - use it. But as a reference.

Andrey Voytenko:

About initialisation. Is it possible to write it this way?

...

Anyway, my favourite initialization via ={0} with strings doesn't work. That's a shame.

Thanks for the post, bug fixed. The fix will be included in the next build.

But it does work in Kovalev's tutorial. What prevents me from copying it correctly and adjusting it to the new requirements?

Sergey Vedmanov 2016.02.02 12:23 #14878

Artyom Trishkin:
But the Kovalev's tutorial still works. What is preventing us from copying it correctly and adjusting it to the new requirements?

I'll surprise you, but it works in other shopping centres too. If you read the post carefully from the beginning...

Specifically on Alpari. Specifically on USD-JPY.

What can we do additionally ???

... ... in other Trading Centres? :)

I saw your specifics. I didn't poke around because I think it's redundant. All those Kovalev terminals...

But in your code I see a discrepancy between stored data and description of this data in the comments - it's already confusing.

Further:

string text=StringConcatenate(" Тикет= Опен= ",a1," ЛОТ!!!= ",a2," ЛОТ 2= ",Aa2," 4= ",a4," 5= ",a5," 6= ",a6," 7= ",a7," 8= ",a8);

your lot is printed from variable a2, but what are we saving to it? Here it is:

Mas_Ord_New[Qnt][2]= OrderLots(); // Курс SL

Or maybe we should print it using DoubleToString() ?

And you are normalizing the lot incorrectly. You need function for lot normalization. I won't search for it. You can search for it at Kim's - it will do for you.

The lot is normalized incorrectly. We need function for lot normalization. I will not search for it. You may look for it in Kim's - it will work for you.

Found it. Thank you. But it does not solve the task at hand.

It works correctly on other CAs and with this code.

It works incorrectly with Kim's function.

It reads correctly via DoubleToString() but calculates incorrectly. I will not count through DoubleToString(). If I go there and back, it transfers strings correctly but doublings of strings are again wrong.

The problem is in Alpari and we need a crutch to bypass it.

USD-SEK incorrectly displays the opening price on another pair.
