MT5 Previous Bar Hi-Lo

Does anyone happen to know how to convert this to MT5 so I can display the previous bars' high and low:

int counted_bars=IndicatorCounted();
double HIGH;
double LOW;
//----
if((Time[0]!=curTime))
{
curTime=Time[0];

HIGH = High[1];
LOW = Low[1];

I've tried numerous things but can't seem to find a solution.

These should do the trick.

If you are working within an indicator you can always access those kind of arrays in the on calculate function without the need to copy them.

Thank you.
