Help looking for an indicator

I have been searching without luck to find an indicator that displays the average range over a specified time period.

For example I want to know the range of GPBUSD over the past 5 days but ONLY for the hours between 5pm and 8am.

I have tried playing around with a few ADR indicators but not being much more than a cut and paste programmer I am really struggling to get anywhere as I need to only use specified hours in the equation ?

Is there anyone who can point me in the right direction ?

Regards

Hi,

I think you can use iBarShift function to list the bars you need, then use iHigh and iLow to get the range.

OR

If your EA can be online every day between 5pm and 8am you can create a cvs with the values you need.
