REQ: Trend Line Indicator

 
I am looking for a Trend Line Indicator that can plot the following:

1) Upper line connecting the higher high of the last 12 bars of the previous day with the higher high of the last 3 bars of the current day

and

2) Lower line connecting the lower low of the last 12 bars of the previous day with the lower low of the last 3 bars of the current day


Timeframe 1 H

Does anyone have such an indicator please?
