Modify existing indicator to adjust time calculation correctly

I have an indicator that was written for me but does not do exactly what I need.

I am calculating pivots using open a close times of the markets. For example if the market opens at 1:00 server and closes at 7:00 server the High is the highest time from 1:00 to 7:00 and the low the lowest from 1:00 to 7:00.

The problem I have is this indicator is coded to only calculate the pivots the next day when server time is 00:00:00.

I need it modified so the pivots are calculated as soon and the market closes so for this example once it has the close price at 7:00 + offset server time it gets the new pivots and does not wait for the server time to tick over to 00:00:00

Here is an Image of what it does now so the open and close lines should be drawn after the close. The close close price has an offset of 5mins in the code as well

I need this specifically to work in tester. At the moment I cant get it to work on a 1min chart in tester so could you also have a look at that. I really don't care what it looks like in the end and all I need is buffers so I can test some simple strategies in tester and see the buffers on the screen so I know its doing what I want.

Also there is some code in there to delete all objects on deinit()  I need this changed to only delete objects of the indicator because it deletes all the trades in tester.
