AccountNumber On Init Validation - page 2

Sorry if wrong. I would be glad if you could teach us.

int OnInit(){

int ac = AccountNumber();

int OnCalculate(const int rates_total,
                const int prev_calculated,

                const double &high[],
                const double &low[],
                const double &close[],
                const long &tick_volume[],
                const long &volume[],
                const int &spread[]){
