Finding the Bar and Open for comparing high and low

How do get a handle on a candle at a specific time like 9:30 am EST so that I can compare its open and low against the current bar?
Example:
def referanceBarLow = GetCandle(930).low
def referenceBarHigh = GetCandle(930).high

if low > referenceBarLow doSomething;
 
In your code you seemed to define the reference bar as the bar at 9:30. I did the same. I just did the low of the candle, but replace 'low' with high, open or close to get the other data points.
 
def referenceBarLow = if SecondsFromTime(0930)==0 then low else referenceBarLow[1];

What is referenceBarLow[1] though. Is it a candle object? If so should it not be referenceBarLow[1].low and then I can get the high value as referenceBarLow[1].high?

But it doesn't compile if I try to treat referanceBarLow[1] as a candle object.
 
Here is the problem statement: I want to compare the candles that come after the market open candle to see if the low value of that candle is lower than the market open candle and alert. How do I do this in thinkscript?

referenceBarLow[1] is the value of referenceBarLow from the last bar. Setting referenceBarLow = referenceBarLow[1] allows you to store the value of the first bar low through the trading day. The code to your problem statement is below. I encourage you to use labels and chart bubbles to see what the code is doing. If you want the reference bar to be the first bar on the chart (instead of the 9:30 bar) then search this site for "firstbarofday".

Ruby:
def referenceBarLow = if secondsTillTime(0930)==0 then low else referenceBarLow[1];
def lowerLowThanOpeningBar = if secondsTillTime(0930)!=0 then low < referenceBarLow[1] else 0;
alert(lowerLowThanOpeningBar,"This Bar Has Lower Low Than Reference Bar", alert.BAR, sound.CHIMES);
addchartbubble(lowerLowThanOpeningBar, high, "ALERT");

Thanks a lot. I really appreciate it. The code, works like a charm. But this one adds a bubble and alerts every time it finds a lower bar than the referenceBarLow. How do I stop showing bubble once it is shown? Only one alert and one bubble between regulartradingstart(getyyyymmdd()) and regulartradingend(getyyyymmdd()). Thanks.

It works. Thank you so much. In my mind I was going crazy thinking I have to use fold and all. You made it very simple. I have modified your code to track both the first high and first low during the market open.
Code:
def referenceBarLow = if secondsTillTime(0930)==0 then low else referenceBarLow[1];
def lowerLowThanOpeningBar = if secondsFromTime(0930) > 0 and secondsTillTime(1600) > 0 then low < referenceBarLow[1] else 0;

def lowConditionCount = if secondsTillTime(0930)==0 then 0 else if lowerLowThanOpeningBar then lowConditionCount[1]+1 else lowConditionCount[1];

alert(lowConditionCount == 1 && lowerLowThanOpeningBar,"This Bar has Lower Low Than Reference Bar", alert.BAR, sound.CHIMES);

addchartbubble(lowConditionCount == 1 && lowerLowThanOpeningBar, high, “L”, Color.RED);

def referenceBarHigh = if secondsTillTime(0930)==0 then high else referenceBarHigh[1];
def higherHighThanOpeningBar = if secondsFromTime(0930) > 0 and secondsTillTime(1600) > 0 then high > referenceBarHigh[1] else 0;

def highConditionCount = if secondsTillTime(0930)==0 then 0 else if higherHighThanOpeningBar then highConditionCount[1]+1 else highConditionCount[1];

alert(highConditionCount == 1 && higherHighThanOpeningBar,"This Bar has Higher High Than Reference Bar", alert.BAR, sound.CHIMES);

addchartbubble(highConditionCount == 1 && higherHighThanOpeningBar, high, “H”, Color.GREEN);

But the trick is to only alert the first high or first low but not both. If you have any insight on how to do that, much appreciated. I will try as well.
 
You just have to add one more condition to the alert statements. Everything you need is there. Let me know what you come up with. :)
Here it is. Thanks again

def referenceBarHigh = if secondsTillTime(0930)==0 then high else referenceBarHigh[1];
