Plot 52-week high/low once using current symbol

[Advancing]

Hello,
Looking to plot 52 week high and 52 week low once and not dynamically update (recalculate) with each tick.

def Start;
def Finish;

if (GetUnderlyingSymbol() == GetSymbol())
{
    Start = Highest(high, 252);
    Finish = Lowest(low, 252);
}
else
{
    Start = Double.NaN;
    Finish = Double.NaN;
}

Using this to show a dashed line for 52wk high, how can i add a price bubble to show on the right axis

def a = Highest(high, 252);
def barNumber = barNumber();
def bar = if IsNaN(a)
then Double.NaN
else BarNumber();
def ThisBar = HighestAll(bar);
def Line = if bar == ThisBar
then a
else Double.NaN;
plot P = if ThisBar
then HighestAll(Line)
else Double.NaN;
P.SetStyle(Curve.Short_Dash);
P.SetLineWeight(1);
P.SetDefaultColor(CreateColor(75,250,150));

@Nikola Add the following snippet to the bottom of your script:

input showBubble = yes;
def SR = showBubble and !IsNaN(close) and IsNaN(close [-1] ) && HighestAll(BarNumber());
AddChartBubble(SR and p, HighestAll(Line), "Highest", Color.RED, yes);

how can i add to the code to show the 52wk low also?

@Nikola Here you go:

def a = Lowest(low, 252);
def barNumber = barNumber();
def bar = if IsNaN(a)
then Double.NaN
else BarNumber();
def ThisBar = HighestAll(bar);
def Line = if bar == ThisBar
then a
else Double.NaN;
plot P = if ThisBar
then HighestAll(Line)
else Double.NaN;
P.SetStyle(Curve.Short_Dash);
P.SetLineWeight(1);
P.SetDefaultColor(CreateColor(75,250,150));

input showBubble = yes;
def SR = showBubble and !IsNaN(close) and IsNaN(close [-1] ) && HighestAll(BarNumber());
AddChartBubble(SR and a, HighestAll(Line), "Lowest", Color.Green, yes);

 

[Nikola]

It wont work in the same script because the "def a" and "plot p".

Can the bubbles be moved to the left so they don't block stuff?

 

[BenTen]

@Nikola Just create two scripts. Not sure about moving the bubbles to the left.

I am looking for a study that I can apply to my charts on thinkorswim that will draw a horizontal line for the previous upward spikes in the chart on a 1 year time frame.
