Midnight and 8:30 New York Open Indicator

I would like an indicator for alerts based on "ICT Midnight and 8:30 Open" by AlphaICTrader on Trading View. You can view the source code.

That indicator draws a line on the midnight and 8:30 newyork open.

It should be modified as follows; 

a). When the midnight session opens, a line should be drawn at the open and another line at the close of the 30 minute bar. The same should be done to the 8:30 new york open. (Basically you are adding a line to show 00:30 close and another to 9:00 am newyork close since the indicator already shows the opening prices)

b). After x number of minutes, price can be within the 30 minute opening range, above it or below. If price happens to be outside the range after x number of minutes (waiting time), then an alert should be send if price is at a distance of x pips away from the nearest line (either closing or opening line).

This alert should be sent only once

Example

If at 8:30 am Newyork open EURUSD opens at 1.09200 and after 30 minutes it closes at 1.09500, then the opening line will be shown at 1.09200 and the closing line at 1.09500. Then after a waiting time of 45 minutes, I find price moved higher to 1:09650. So this confirms that price has closed outside the opening range 45 minutes later. At this time the nearest line is the closing line at 1.09500. Price can go higher or lower but when it gets to say 5 pips to the closing range at 1.09500 which happens to be the nearest line then an alert should be sent once. 

Hope this will explain the logic

Thanks
