Help coding X period high/low indicator

Hi,

Can anyone code a very simple indicator that would show X period High and Low. Sometimes people call it the Donchian Channel.

there are indicators on the web but they all include the sunday candle. Could anyone code one that it would not include the Sunday Bar?

Screenshot is attached of how it looks.
