Sorry for my english, i just started to lern pine script I make an Indicator wir support and resistance lines with some help von AI.

It works good, but i have a Problem if i want to “Reset chart view”, it is very small to show all the lines.

//@version=5
indicator("Levels", overlay=true)

// Line color option
lineColor = input(color.new(color.blue, 30), title="Line Color")

// Settings for line display
showLines = input(true, title="Show Lines", group="Levels")

// Arrays to store line IDs and their corresponding support/resistance levels
var float[] supportLevels = array.new_float()
var line[] supportLines = array.new_line()
var float[] resistanceLevels = array.new_float()
var line[] resistanceLines = array.new_line()

// Function to identify bullish and bearish candles
isBullishCandle(open, close) =>
    close > open

isBearishCandle(open, close) =>
    close < open

// Function to check if a bearish candle follows a bullish candle
isBearishAfterBullish() =>
    isBullishCandle(open[1], close[1]) and isBearishCandle(open, close)

// Function to check if a bullish candle follows a bearish candle
isBullishAfterBearish() =>
    isBearishCandle(open[1], close[1]) and isBullishCandle(open, close)

// Variable to store the new support level
var float supportLevel = na

// Check for new support levels
if showLines and isBullishAfterBearish()
    supportLevel := low
    array.push(supportLevels, supportLevel)
    supportLineID = line.new(x1=bar_index, y1=supportLevel, x2=bar_index + 10, y2=supportLevel, color=lineColor, width=1, extend=extend.right)
    array.push(supportLines, supportLineID)

// Update existing support lines and delete if broken
i = array.size(supportLevels) - 1
while i >= 0
    supportLevel := array.get(supportLevels, i)
    supportLineID = array.get(supportLines, i)
    
    if (close < supportLevel)
        line.delete(supportLineID)
        array.remove(supportLevels, i)
        array.remove(supportLines, i)
    else
        line.set_x2(supportLineID, bar_index + 10)
    i := i - 1

// Variable to store the new resistance level
var float resistanceLevel = na

// Check for new resistance levels
if showLines and isBearishAfterBullish()
    resistanceLevel := high
    array.push(resistanceLevels, resistanceLevel)
    resistanceLineID = line.new(x1=bar_index, y1=resistanceLevel, x2=bar_index + 10, y2=resistanceLevel, color=lineColor, width=1, extend=extend.right)
    array.push(resistanceLines, resistanceLineID)

// Update existing resistance lines and delete if broken
j = array.size(resistanceLevels) - 1
while j >= 0
    resistanceLevel := array.get(resistanceLevels, j)
    resistanceLineID = array.get(resistanceLines, j)
    
    if (close > resistanceLevel)
        line.delete(resistanceLineID)
        array.remove(resistanceLevels, j)
        array.remove(resistanceLines, j)
    else
        line.set_x2(resistanceLineID, bar_index + 10)
    j := j - 1

I tried with scaling=scaling.none, but the lines don`t follow the price.
