Referencing Last week close value inside an hourly chart

I am inside an hourly chart but will like to reference last week close value.

If I use CLOSE(1) this refers to last hour. But what I want is last Week close.
How can I achieve this please within the 1 hour timeframe.

As you are referring hourly candle time frame, weekly OHLC is not defined, as it is not possible to check with two different time frame OHLC
