Find the highest and lowest value for a time frame in the pine editor

As an absoulutely new beginner I'm experimenting with the pine editor of Tradingview. I wrote a simple script that plots the difference between ema and dema. Additionally, I want to get the highest and lowest value in the choosen time frame.

Let's assume the highest closed value of a stock is $120,3 and the lowest closed value is $49,41 in the 6M time frame. I want to plot these two horizontal lines that represents all-time high and all-time low for a specific time frame.

study(title="Test")

biggest(series) =>
    max = 0.0
    max := nz(max[1], series)
    if series > max
        max := series
    max

smallest(series) =>
    min = 0.0
    min := nz(min[1], series)
    if series < min
        min := series
    min

fast = 14, slow = 50

length = input(fast, minval=1)
src = input(close, title="Source")
e1 = ema(src, length)
e2 = ema(e1, length)
dema = 2 * e1 - e2

band4 = hline(0, "Upper Band", color=#ff0000)

fastEMA = ema(close, fast)
slowEMA = ema(close, slow)
test = (dema - slowEMA)//(high1-low1)
plot(test,color=color.white)

var hi = 0.0
var lo = 10e10
var br = 0
var lnhi = line.new(na, na, na , na)
var lnlo = line.new(na, na, na , na)

if change(time(period))
    hi := test
    lo := test
    br := bar_index
    lnhi := line.new(br, hi , br, hi, color=color.red, width=2)
    lnlo := line.new(br, lo , br, lo, color=color.green, width=2)
    float(na)
else
    hi := max(test, hi)
    lo := min(test, lo)

line.set_xy1(lnhi, br, hi)
line.set_xy2(lnhi, bar_index, hi)
line.set_xy1(lnlo, br, lo)
line.set_xy2(lnlo, bar_index, lo)

    Your plot test with the ABSOLUTE HIGHEST and LOWEST value for six months time frames. enter image description here
