I put together this very simple indicator that draws horizontal lines showing the High - Low - Middle of the candle you define in its properties. I also added levels above and below which you can turn on and off.
Use the following to define the timeframe you require
0=CURRENT
5=M5
15=M15
30=M30
60=H1
240=H4
1440=D1
10080=W1
43200=MN1
Set Shift to 1 to look back 1 candle etc.
Hope it is useful to someone
