Is this same as Mark% Change ?

#percentchg

declare lower;

input hiAlert = 0;
input length = 14;
input loAlert = 0;
input price = close;

assert(length > 0, "'length' must be positive: " + length);

plot PercentChg = 100 * (price / price[length] - 1);
plot pHiAlert = hiAlert;
plot pLoAlert = loAlert;

PercentChg.DefineColor("HiAlert", GetColor(5));
PercentChg.DefineColor("Normal", GetColor(7));
PercentChg.DefineColor("LoAlert", GetColor(1));
PercentChg.AssignValueColor(if PercentChg > hiAlert then
PercentChg.color("HiAlert") else if PercentChg < loAlert then
PercentChg.color("LoAlert") else PercentChg.color("Normal"));
pHiAlert.SetDefaultColor(GetColor(8));
pLoAlert.SetDefaultColor(GetColor(8));

If not what is code for Mark% Change?
Thank you all in advance!

Solution
I got it! Label

input priceType = PriceType.MARK;
def change = (close(priceType = priceType) - close(period = AggregationPeriod.DAY)[1])/close(period = AggregationPeriod.DAY)[1];
AddLabel(yes, "change percent is " + change * 100);
I got it! Label

input priceType = PriceType.MARK;
def change = (close(priceType = priceType) - close(period = AggregationPeriod.DAY)[1])/close(period = AggregationPeriod.DAY)[1];
AddLabel(yes, "change percent is " + change * 100);

How can I write %MARK >20% This is my attempt, but it is wrong? Any help is appreciated!

input priceType = PriceType.MARK;
def change = (close(priceType = priceType) - close(period = AggregationPeriod.DAY)[1])/close(period = AggregationPeriod.DAY)[1]> .20 ;

input hiAlert = 0;
input length = 14;
input loAlert = 0;
input price = close;

plot PercentChg = 100 * (price / price[length] - 1);

Looks right.
