pip_spread_on_chart indicator

Hi,
need help with an indi, which should automatically show on an open chart

spread
top chart minus bottom chart amount of pips on default chart for different time frame
(also turn on/off different time frames)
indi should look like what's showing on attached chart for CHFJPY (H4 time frame)
also if one "squeezes/expands" time frame, indi should change.
how tough is this to program?

7 spread
115 M15 (101.30-100.15)
265 H4 (101.40-98.75)
1125 WK (103.10-91.85)

Thanks
