The number of copied array elements or -1 in case ofan error.

There is also ArraySize...

fxsaber:

As it happens, I've never encountered an array where not all elements are copied, it either copies all the requested elements, or it doesn't copy and -1

P.S. Ah, I see why you wroteArraySize, I originally wrote it the same way, but then replaced it with Bars for clarity

Especially surprising is the fact that there is no mention of this in the MT4 helpdesk.

int Bars

Количество баров на текущем графике.

Пример:

int counter=1;   for(int i=1; i<=Bars; i++)     {      Print(Close[i-1]);     }

Alexei, even in your post there is a link with examples and explanations.

int  Bars(
   string           symbol_name,     // имя символа
   ENUM_TIMEFRAMES  timeframe,       // период
   datetime         start_time,      // с какой даты
   datetime         stop_time        // по какую дату
   );

Exactly the same as in mql5
