Andrey Sokolov:

is it a forex broker or something?

It is a BANK.

Andrei Sokolov 2021.02.02 15:42 #13732

MakarFX:
This is BANK.

It's not clear, but okay.

They write that this is available onthe MICEX (FORTS), and Alpari also said that they have it on competitive accounts.

Perhaps with the expressions "only", "always". "never", "no one but" and the like should be more careful.

Can you tell me, in regular trading accounts, whena broker closesan open positionand then reopens it?

Can you tell me ifthere is a situation on a regular trading account wherethe broker has closedthe open positionsand opened them again?

It is an individual situation, in Ukraine banks are required by law to close transactions in the foreign exchange market during the current day (for reporting purposes).

Dear Professionals. We need some help. For example we have a MACD indicator. Its structure is iMACD(NULL,0,InpFastEMA,InpSlowEMA,InpSignalSMA,PRICE_CLOSE,MODE_MAIN,0). How can I change NULL to get calculations not for this currency pair but for another one on the same currency pair chart? I put iMACD("USDJPY",0,InpFastEMA,InpSlowEMA,InpSignalSMA,PRICE_CLOSE,MODE_MAIN,0), but it brings me nowhere. All calculations are null. What's wrong with it?

Is there a "USDJPY" symbol in the market overview?

Alexey Viktorov:

Is the symbol "USDJPY" present in the market overview?

Yes. It is, Victor.

Michail_David 2021.02.02 19:05 #13738

SanAlex:

and if you cheat like this.

Alex, it won't work. The indicator is supposed to draw two MACDs simultaneously for two currency pairs. However, with this code it is getting impossibly bloated. I also want to add calculation of correlation. But thanks for the tip on how the currency pair should be specified.

If I understand correctly, the currency pair should be specified as "EURUSD" in any indicator. In this regard, my question is

void OnInit()

  {
input string Currency = "JPY"; //Выбор валютной пары
input string Major_pair = "USD"; // Выбор валюты для корреляции
input bool Direct_correlation = true; // Выбор прямой и обратной корреляции
string Major_currpair = Symbol();
string two_pair;
//--------------------------------------------------------------------
int position =StringFind(Major_currpair,Major_pair,0);
   if(position == -1)
      Print("Не верно указана валюта корреляции");
   if(Direct_correlation == true)
      two_pair =StringConcatenate(Currency,Major_pair);
   else
      two_pair =StringConcatenate(Major_pair,Currency);
   Print("Two_pair = ", two_pair);
   Print("Major_currpair = ",Major_currpair);
}

How can I insert the symbol " in string? Because the currency pair is printed in the journal as USDJPY, not "USDJPY".

How can I insert the " symbol in the line? As the currency pair in the magazine is printed as USDJPY instead of "USDJPY".
