Returns information about the state of historical data. There are 2 variants of function calls.

Directly returns the property value.

long  SeriesInfoInteger(
   string                     symbol_name,     // symbol name
   ENUM_TIMEFRAMES            timeframe,       // period
   ENUM_SERIES_INFO_INTEGER   prop_id          // property identifier
   );

Returns true or false depending on the success of the function run.

bool  SeriesInfoInteger(
   string                     symbol_name,     // symbol name
   ENUM_TIMEFRAMES            timeframe,       // period
   ENUM_SERIES_INFO_INTEGER   prop_id,         // property ID
   long&                      long_var         // variable for getting info
   );
