Plot price levels using daily change in price

Hi folks, new to thinkscript. I am trying to plot price levels using daily high/low values. Basically if the day close is +/- 2% from the prior day high or low, then plot a price line at prior day close.

The code is a rather simpler implementation. I am looking at last day close and comparing the change with the current day close.
How do I plot the multiple price levels -- extending to the right.
I suspect I have to use "fold" somehow ?


Code:
def price = close(period="DAY");
def change = (absValue(price [1] -price)/price [1]) * 100 ;
def level = if  change>= 2 then price else Double.nan;  # 2% change
plot p01 = (if !isNan(level) then level else double.nan);
 
Solution
Code:
def price = close(period="DAY");
def change = (absValue(price[1] - price) / price [1]) * 100 ;
def level = if  change>= 2 then price else level[1]; 
plot p01 = level;
p01.setPaintingStrategy(paintingStrategy.HORIZONTAL);

This will extend the most recent level, until a new one is established. You can not continue to extend multiple lines in thinkscript though, at least not in an effective manner using arrays as you might in other languages.

You would have to hard-code each of them independently, and create a fake array by shifting each variable to the next when a new entry is detected.

Var3 = Var2
Var2 = Var1
Var1 = NewValue

If no new value is detected, assign prior values.

Var3 = Var3[1]
Var2 = Var2[1]
Var1 =...
