Modifying 1 pre-made indicator_2004252212

I have a request of modifying current “OIH_LondonBreakout_v1.0” indicator to have always same period (06:00 ~ 09:00) even if summer time is adjusted or not.
“OIH_LondonBreakout” indicator has “Start Time” and “End Time” to calculate the box.
To have same period (06:00 ~ 09:00), I think “OIH_Session_v1.0” indicator is useful to calculate the time period.
With the feature of “OIH_Session_v1.0”, new “OIH_LondonBreakout” indicator doesn’t need to adjust to have same time period (06:00 ~ 09:00) in summer time or non-summer time.
Firstly, take a look at below image, please.

As you can see, “OIH_Session_v1.0” indicator shows areas of each session.
I think this automatic calculation is useful to have specific period (06:00 ~ 09:00) automatically without adjusting time when summer time started or ended.

a look at another image below, please.

As I said above, “OIH_Session_v1.0” is to help to have same period (06:00 ~ 09:00) in summer time or non-summer time.
And I don’t need any objects on chart or buffers in data window of “OIH_Session_v1.0”.
Because I need only the calculation of self-adjusting of the time period (06:00 ~ 09:00) automatically without manual adjusting time in new “OIH_LondonBreakout” indicator.
With this feature of self-adjusting time, new “OIH_LondonBreakout” will be not necessary to be adjusted to have the time period in summer time or non-summer time.

New “OIH_LondonBreakout” will have below function in parameter.
〮 Automatic Session   True     ** New option
〮 Start Time          06:00     ** Current option
〮 End Time           09:00     ** Current option

For more details, take a look at my document attached, please.
Thanks,
