Hello, I am writing an EA for NzdUsd and using in its calculations the value of the moving average from another currency pair AudUsd.
When I'm testing the indicator on another symbol I get a null value.
Is it the inability of MQL4 itself to receive an indicator value on other pairs during testing?

double AudUsd = iMA("AUDUSD",0,Period,0,MODE_SMA,PRICE_CLOSE,i); //Выдаёт нулевой результат при тестировании на другой паре (NzdUsd) 

And please advise the actual forex broker that has an archive of quotes for testing.

This is an inability of MT4

Then it's like this

The market is now open and the button is pushed back a bit, sometimes after more than a second.

Makar, don't mislead people. I foolishly thought that some changes have been made that I don't know about... I even tested it on EURUSD

int sd;
/*******************Expert initialization function*******************/
int OnInit()
 {
  sd = (int)MarketInfo("EURJPY", MODE_DIGITS);
  return(INIT_SUCCEEDED);
 }/******************************************************************/

/************************Expert tick function************************/
void OnTick()
 {
  datetime lt = iTime(_Symbol, PERIOD_M15, 0);
  static datetime ct = 0;
  if(ct != lt)
  {
   ct = lt;
   Print(DoubleToString(iMA("EURJPY", PERIOD_M15, 21, 0, MODE_SMA, PRICE_CLOSE, 0), sd));
  }

I'm not able to open orders on other pairs in the mt4 tester, everything else is available without any problems.

Check the availability of AUDUSD quotes for the required timeframe

I don't know how to open orders on other pairs in the mt4 tester, everything else is available to me without any problems.

Maybe something is wrong? Also, it is not possible to obtain data of bars from other symbols according to tester time, it will be obtained by current time. That's why I can't test the multicurrency even just in the calculation part in 4ka.

I always thought that MT4 tester fully emulates the environment of a single instrument, and MT5 the entire environment that is available.

Or is it not?
