All time high & 52 weeks high label & bubble on the chart

[x718style]

Hello!
Can someone help me with the following script?
First, I'm trying to display only the dollar value without the decimal point?
Second, I'm looking for the script that displays the all time high and low in the chart.
---
AddLabel(1, Highest(high(period = AggregationPeriod.MONTH), 120), Color.GRAY);
AddLabel(1, Highest(high(period = AggregationPeriod.WEEK), 52), Color.GREEN);

So like this?

##HighOfYear
def High52Week = Highest(High(period = "Day"), 252);
AddLabel(1, (High52Week), Color.Cyan);
plot HighofYear=High52Week;
