What is the data type for timeframes in MQL5?

[peterbabs]

In MQL4, below code works pretty well.
But in MQL5, I'm getting errors when I make the timeframe an int variable.
What's the data type for declaring the timeframe (e.g. PERIOD_H1 ) as a variable/placeholder in MQL5? I can't seem to find it in the documentation.

I need to maintain TF as a variable.
Your advise is appreciated.

string Pair;
extern int TF=PERIOD_H1;
double lastBarRange;

void GetLastBarRange(){
lastBarRange = iClose(Pair,TF,1) - iOpen(Pair,TF,1)
}

void OnTick(){

Pair="EURUSD";  GetLastBarRange();

}

Use  ENUM_TIMEFRAMES enumeration

Perhaps you should read the manual. List of MQL5 Constants → PERIOD_H1 → Chart Timeframes → ENUM_TIMEFRAMES

Thank you all.

I figured it out after posting.

Didn't know previously that ENUM_TIMEFRAMES is actually a data type.
