how to create scan that compares value to high price of a specific time interval?

Hello,

I'm trying to create a scan for an afternoon breakout. The main criteria for the breakout is that the price must move up at least 30% above the high price between open and noon, at any time after noon.

This is meant to run at the end of the day just to check for any occurrences throughout the day. The way I wanted to do that was by getting the high price from open to noon (the morning high), and then checking to see if the price at any point between noon and close (i.e. in the afternoon) was greater than that morning high.

I don't have a lot of experience with thinkscript, but I've tried adapting the code in this post to get what I need. I haven't really been successful. I'm stuck on what a "volume profile" is and how to use it. The documentation is not very helpful.

Any help would be appreciated.

@redicarus scan for 'Above_First_Session_High_Plot' being true.
Ruby:
input First_Session_Start_Time = 0930;
input Session_Split_Time = 1200;
input Second_Session_End_Time = 1630;
input Percentage = 0.00;

def First_Session_High;
if SecondsTillTime(First_Session_Start_Time) == 0 {
First_Session_High = high;
} else if high > First_Session_High[1] and SecondsTillTime(Session_Split_Time) >= 0 {
First_Session_High = high;
} else {
First_Session_High = First_Session_High[1];}

plot First_Session_High_Plot= if SecondsFromTime(Session_Split_Time) > 0 and SecondsTillTime(Second_Session_End_Time) >= 0 then First_Session_High+(First_Session_High*Percentage) else Double.NaN;

def Above_First_Session_High = if SecondsTillTime(First_Session_Start_Time) == 0 then 0 else if high > First_Session_High+(First_Session_High*Percentage) then 1 else Above_First_Session_High[1] ;

plot Above_First_Session_High_Plot = Above_First_Session_High;
Above_First_Session_High_Plot.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
Above_First_Session_High_Plot.Hide();

This is great, thank you so much!!

for this part:
Ruby:
def First_Session_High;
if SecondsTillTime(First_Session_Start_Time) == 0 {
First_Session_High = high +(high*Percentage);
} else if high > First_Session_High[1] and SecondsTillTime(Session_Split_Time) >= 0 {
First_Session_High = high +(high*Percentage);
} else {
First_Session_High = First_Session_High[1];}

why do you add the high multiplied by the percentage?

Edit: I think I understand, it would be the same as doing this instead, right?
Ruby:
def Above_First_Session_High =
if SecondsTillTime(First_Session_Start_Time) == 0 then 0
else if high > First_Session_High+(First_Session_High*Percentage) then 1
else Above_First_Session_High[1] ;

@redicarus I make a mistake, Your change is correct. Updated the code in last post.
oh nice. I'm running into another issue, it seems the script works perfectly fine on some stocks but not all. For example, here's ELAN, one of the stocks that came up when I used the script on the scanner (for 20% breakouts):

several such cases in the screener, not sure if it's because I'm running it at 2AM. I'll try debugging tomorrow, but maybe you could identify the issue more easily.
