Modifying an existing "Daily Open lines" indicator (mq4)

Hello I would like to do two modifications to an existing MT4 MQ4 indicator file from MetaTrader 4 platform to my specific needs.

The indicator currently draw the 3 horizontal lines. (One horizontal AQUA Line for Daily open position, 2 horizontal lines, one in LIME is x pips higher than Daily open position, and the other one in RED is x pips lower than the Daily open position. Those 3 lines will move according to the new Daily open position.)

Here are the two modifications needed:

1) I need the same but with an adjustable time shift field in the setting for the daily open line. For example GMT: -5 , GMT: 2, etc.

2) Add an alert window to the indicator. I would like for the alert to come up whenever the price is about x pips to touches the upper (LIME) or lower (RED) horizontal lines (Not the central open line in Agua color). I want to be able to switch off the alert and if possible alert also need to have some kind of timer that don't alert more than one time per x candles.

I must be able to modify all the options in the indicator (Time Shift, switch off alert, number of pips before alert). Everything else stays the same.

Attached is the indicator.

Thanks
