how to plot the change in price in the day from the previous day's close

[DanielManahan]

I want to plot the change from the current candle from the price at the previous day's close. similar to how the watchlist column "MarkChange"

declare lower;

input getTicker1 = "";
def Agg1 = AggregationPeriod.DAY;

def changeTicker1 = close(Period = Agg1, getTicker1)[1] - close(getTicker1);

plot data1 = changeTicker1;
plot line1 = 0;

I am getting an error

things to try,
put a real symbol in as a default value on first input. = "SPY";


symbol parameter in wrong sequence in close.

def changeTicker1 =
close(Period = Agg1, getTicker1)[1] -

symbol is the first parameter, but you have it as 2nd. you didn't include symbol = , like you included period = .

well I tried switching the order but can't get the syntax to work. and including default SPY. from the reference you linked.

this is confusing
