ATR Levels Indicator Daily to Weekly Opening

[SwitchTrader]

Hi All,
I have this ATR indicator originally compiled by Bill Jones. What I am trying to do is to get it to open at 00:00 Hours every Sunday which is market open for me. As those in the know will see it's opening daily just now. I have managed to get the ATR changed from Daily to Weekly but as for what to change for the time frame I am stuck. I can change the opening times easily enough. Could someone show me where I should be looking and what I need to change? Would it be possible add an input to get it to open Monthly, Weekly and Daily even? Here's the code I have with the ATR Period already changed.

Thanks in advance for your help?

It is not that easy to modify it to show a Weekly open ATR level. Currently it uses a cycle with this condition to find the day start bar:

      if(TimeToStr(Time[dayshift],TIME_MINUTES)=="00:00") break;  // Find the 5pm NY bar.

You need to modify it to find the bar that fits your definition of "Sunday open".

This one does what you asked for. You can set the day of the week (Sunday by default), hour and minute (00:00 by default) and it will find that candle and place the weekly ATR lines starting from there.
