Hi,

looking for some help on modifying on an indicator that would draw the previous period's (month & week) high & low with a horizontal line beginning from that specified candle to the right of the chart.

The current indicator only shows the high and low levels drawn beginning at the current month (second screengrab & code below).

Desired output (white lines there for reference)
