Overnight Open Study Line?

[ckab]

I'd like a study that simply draws a line since the overnight market open rightwards. I'm using this below script but it's not working as intended:

def MarketOpenPrice = if SecondsFromTime (0930) == 0 && SecondsTillTime(0930) == 0 then open else marketopenprice[1];


plot Opening_Price = if SecondsFromTime (0000) >= 0 and SecondsFromTime(1700) <= 0 then MarketOpenPrice else Double.NaN;

From the screenshot below you can see that it appears to be functioning correctly but then at 9:30 it jumps up to the market open price. Any insight here?

use different words to describe what you want.
you say this,
overnight market open
which i have no idea what it means.

then you use a daytime market open time of 930....
so on every 9:30 bar, it reads a new price, and starts a new line price level.

do you mean the bar after daytime close? 4pm?
