1st bar to through whole number on a 1 minute chart

[jtbiz]

Hello everyone! I am looking for thinkscript code to identify the 1st barnumber that went through a whole number on a 1 minute chart today.

def target = whole number; #need help here
def thru = high>target and low<target;
plot arrow = thru; #need way to plot arrow on 1st bar that crosses not everytime a bar goes through a whole number
arrow.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
arrow.AssignValueColor(Color.cyan);
arrow.SetLineWeight(1);

see example in pic attached

As far as defining the target bar:

def RoundedHigh = RoundDown(High,0);
def RoundedLow = RoundUp(Low,0);
def thrutarget = High > RoundedHigh and Low < RoundedLow and RoundedHigh >= RoundedLow;

plot arrow = thrutarget;
arrow.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
arrow.AssignValueColor(Color.cyan);
arrow.SetLineWeight(1);

plot arrow = thru; #need way to plot arrow on 1st bar that crosses not everytime a bar goes through a whole number

I'll assume you mean not every bar through same whole number as previous arrow.
Took the liberty of differentiating between crossing above or below.

input Day_Start = 0930;

def GreenBar = close > open;
def RedBar = close < open;
def RoundedHigh = RoundDown(High,0);
def RoundedLow = RoundUp(Low,0);

def thrutarget;
def BlackWhole;
if SecondstillTime(Day_Start)[-1] == 0 {
thrutarget = 0;
BlackWhole = 0;
}else if High > RoundedHigh and Low < RoundedLow and RoundedHigh >= RoundedLow 
            and (RoundedHigh + RoundedLow)/2 <> BlackWhole[1] {
thrutarget = 1;
BlackWhole = (RoundedHigh + RoundedLow)/2;
}else {
thrutarget = 0;
BlackWhole = BlackWhole[1];} 

plot uparrow = if Greenbar then thrutarget else double.nan;
uparrow.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
uparrow.AssignValueColor(Color.cyan);
uparrow.SetLineWeight(1);

plot dnarrow = if Redbar then thrutarget else double.nan;
dnarrow.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);
dnarrow.AssignValueColor(Color.cyan);
dnarrow.SetLineWeight(1);

Beautiful! Thank you possible to change to 1st bar only irrespective of crossing above/below. so in that case only the 1st bar going thru' a whole number will have an arrow.

That is how it is currently written.
The only issue I foresee as of now is if a bar passes through 2 whole numbers. A subsequent bar passing through only 1 of the 2 whole numbers would still signal.

applied code to attached example. It appears that it would trigger alert 3 times when price crosses 54. I'm wanting to generate an alert just the 1st time it crosses a whole number. So in the example, once each the 1st time stock touches the whole numbers 57, 56,55,54,53

Not sure if possible since we cant use arrays, but this might work:

input Day_Start = 0930;
input Day_End = 1630;

def Active = SecondsFromTime(Day_Start) >= 0 and SecondsTillTime(Day_End) >= 0;
def GreenBar = close > open;
def RedBar = close < open;
def RoundedHigh = RoundDown(High,0);
def RoundedLow = RoundUp(Low,0);

def thrutarget;
def BlackWholeH;
def BlackWholeL;
if SecondstillTime(Day_Start)[-1] == 0 {
thrutarget = 0;
BlackWholeH = hl2[-1];
BlackWholeL = hl2[-1];
}else if Active and High > RoundedHigh and Low < RoundedLow and RoundedHigh >= RoundedLow 
        and (RoundedHigh > BlackWholeH[1] or RoundedLow < BlackWholeL[1]) {
thrutarget = 1;
BlackWholeH = if RoundedHigh > BlackWholeH[1] then RoundedHigh else BlackWholeH[1];
BlackWholeL = if RoundedLow < BlackWholeL[1] then RoundedLow else BlackWholeL[1];
}else {
thrutarget = 0;
BlackWholeH = BlackWholeH[1];
BlackWholeL = BlackWholeL[1];}

plot uparrow = if Greenbar then thrutarget else double.nan;
uparrow.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
uparrow.AssignValueColor(Color.cyan);
uparrow.SetLineWeight(1);

plot dnarrow = if Redbar then thrutarget else double.nan;
dnarrow.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);
dnarrow.AssignValueColor(Color.cyan);
dnarrow.SetLineWeight(1);

what kind of first do you want?
the first time , each day, or week, or month,..?
or the first time on the chart?


an example of acting on the first signal and ignoring the rest.
