I want to get the High price for the next higher timeframe

int timeFrame[] = {1,5,15,30,60,240,360,1440,10080,43200},nextTF;

int init()
{
for(int i=0;i<ArraySize(timeFrame);i++){
if(i==ArraySize(timeFrame)-1){nextTF=timeFrame[i];Print("Sorry maximum time frame reached");break;}
if(timeFrame[i]==Period()){nextTF=timeFrame[i+1];break;Print("i "+i);}
}
}

if( Period() == PERIOD_M5 )
{
  iHigh(NULL,t,1);
}
