In the Experts tab.

I don't find it

Is it in MetaEditor or in MT5?

For the Strategy Tester, but also on Live trading, you have to always first synchronise the symbol data you plan to use.

Please read the following ... Documentation on MQL5: Timeseries and Indicators Access / Organizing Data Access

However, just to prove the point, here is some sample EA code with a quick and dirty way to synchronise the symbol data. Don't use this on a real EA.

For a proper way, read the link above. This was just for a quick sample ...

string sSymbols[] = {
   "EURUSD",   // Enabled on Market Watch
   "GBPUSD",   // Disabled on Market Watch
   "EURGBP",   // Enabled on Market Watch
   "USDJPY",   // Disabled on Market Watch
   "XAUUSD"    // Enabled on Market Watch
   };

void OnTick( void ) {
   // Synchronise first (not very well written, just a quick & dirty way )
      uint nCount, nSymbolCount = sSymbols.Size();
      do {
         nCount = 0;
         for( uint i = 0; i < nSymbolCount; i++ ) {
            string sSymbol = sSymbols[i];
            nCount += iTime( sSymbol, _Period, 0 ) > 0 ? 1 : 0;
            };
      } while( nCount < nSymbolCount );
         
   // Check sessions
      for( uint i = 0; i < nSymbolCount; i++ ) {
         string sSymbol = sSymbols[i];
         datetime dtFrom = WRONG_VALUE, dtTo = WRONG_VALUE;
         ResetLastError();
         if( SymbolInfoSessionQuote( sSymbol, TUESDAY, 0, dtFrom, dtTo ) )
            Print( i, ") ", sSymbol, ": Tuesday from ", dtFrom, " to ", dtTo );
         else
            Print( i, ") ", sSymbol, ": Error ", _LastError );
      };

   // Exit the program
      ExpertRemove();
};
