High and Low of the day Arrow

[supertrader]

Hello thinkscript community,

I need help creating a script to show a single down arrow at the highest candle of day and a single up arrow at the lowest candle of the day. I have drawn in the arrow myself to show exactly what I am looking for.
I appreciate all the help I can get. Thank you very much.

this will plot those arrows
it uses 2nd aggregation to find the highest high and lowest low, for each day.
then it compares every high in a day to the highest high (similar for low).
when the prices match, it plots an arrow.
if 2 candles have the same highest high, there will be 2 arrows.

#hilo_day

def na = double.nan;
def bn = barnumber();

def agg = aggregationperiod.day;
def hiday = high(period = agg);
def loday = low(period = agg);

plot z1 = if hiday == high then high else na;
z1.SetPaintingStrategy(PaintingStrategy.ARROW_down);
z1.SetDefaultColor(Color.magenta);
z1.setlineweight(2);
z1.hidebubble();

plot z2 = if loday == low then low else na;
z2.SetPaintingStrategy(PaintingStrategy.ARROW_up);
z2.SetDefaultColor(Color.cyan);
z2.setlineweight(2);
z2.hidebubble();
