This script is designed to visually highlight certain price levels during a specified trading session on an intraday chart (10:45AM). It draws horizontal lines at the high and low prices of the session. The problem is that when I change the timeframe, the lines changes its location. I want lines to be drawn on the high and low on 10:45 AM candle, and not change when I change the timeframe.

below the code plot diffrent lines value. I just want to plot same value whenever I change the timeframe. I tried to use request.security function but not working.

//@version=6
indicator('Lines', overlay = true, max_lines_count = 500)

// Define the trading session
tradingSession = input.session('1045-1525', title='Trading Session')

// Function to determine if the current bar is the first bar of the session
isSessionFirstBar() =>
    t = time('D', tradingSession)
    na(t[1]) and not na(t) or t[1] < t

// Check if today is the current day
isToday = (year(timenow) == year(time) and month(timenow) == month(time) and dayofmonth(timenow) == dayofmonth(time))

// Condition to check if we're in an intraday timeframe and it's the first bar of the session
intraCondition = timeframe.isintraday and isSessionFirstBar()

// Draw lines if the condition is met
if intraCondition
    // Draw lines at high and low for 6 hours into the session
    line.new(time, high, time + int(6 * 60 * 60 * 1000), high, xloc.bar_time, width = 2, color=color.green)
    line.new(time, low, time + int(6 * 60 * 60 * 1000), low, xloc.bar_time, width = 2, color=color.red)

So, this is actually a complicated task. Your script will be executed on each bar. For a 5-min timeframe, getting the 5min range at 10:45 is not a problem because there is a bar at 10:45.

However, when you switch to 10-min timeframe, it is not as easy. Because you have a bar at 10:40 and then 10:50. So, 10:45 is somehow intrabar price action.

To get that, you should use request.security_lower_tf() and try to find your range from the array it returns.

Here is a simplified code to get you started, however, there are some corner cases you should be checking. Below code is designed to get the 5 min range at 10:45 from higher timeframes.

//@version=6
indicator('Lines', overlay = true, max_lines_count = 500)

start_time_unix = timestamp(year, month, dayofmonth, 10, 45, 0)
was_sess_start_on_mid_prev_bar = (time[1] < start_time_unix) and (time > start_time_unix)

[prev_high, prev_low, prev_time] = request.security_lower_tf(syminfo.tickerid, "5", [high[1], low[1], time[1]])

len_time = array.size(prev_time)
sess_high = 0.0
sess_low = 0.0

if ((len_time > 0) and was_sess_start_on_mid_prev_bar)    
    for i = 0 to len_time - 1
        t = array.get(prev_time, i)
        
        if (t == start_time_unix)
            sess_high := array.get(prev_high, i)
            sess_low := array.get(prev_low, i)
            break

if (timeframe.isintraday and was_sess_start_on_mid_prev_bar)
    // Draw lines at high and low for 6 hours into the session
    line.new(time[1], sess_high, time + int(6 * 60 * 60 * 1000), sess_high, xloc.bar_time, width = 2, color=color.green)
    line.new(time[1], sess_low, time + int(6 * 60 * 60 * 1000), sess_low, xloc.bar_time, width = 2, color=color.red)
