I'm not sure why but when I display a different ticker's value on chart the values don't seem to be correct. To test this I have displayed the input ticker over the current chart but that input ticker is just the same chart. It has the same behaviour if you display it over a different chart.

here is the code, but for some reason its grabbing a weird number for the close. The open seems to be correct.

I'm only really interested in getting ES (CME_MINI:ES!) and NQ (CME_MINI:NQ!) values. Even if you specify the contract it also doesn't seem to give the correct value.

indicator("Daily Open and Previous Close Levels with Custom Ticker", overlay=true)

// Input for custom ticker
custom_ticker = input.symbol("", "Custom Ticker (leave blank for current symbol)", group="Symbol")
// Use the specified ticker or the current symbol if blank
ticker_to_use = custom_ticker == "" ? syminfo.tickerid : custom_ticker

// Get the daily timeframe values
[daily_open, daily_high, daily_low, daily_close] = request.security(ticker_to_use, "D", [open, high, low, close], lookahead=barmerge.lookahead_on)

// Get the previous day's close
prev_day_close = request.security(ticker_to_use, "D", close[1], lookahead=barmerge.lookahead_on)

// Colors
daily_open_color = input.color(color.blue, "Daily Open Color", group="Colors")
prev_close_color = input.color(color.red, "Previous Day Close Color", group="Colors")

// Line width
line_width = input.int(1, "Line Width", minval=1, maxval=4, group="Settings")

// Display options
show_daily_open = input.bool(true, "Show Daily Open", group="Display")
show_prev_close = input.bool(true, "Show Previous Day Close", group="Display")
show_labels = input.bool(true, "Show Labels", group="Display")

// Show indicator info
show_ticker_info = input.bool(true, "Show Ticker Name on Labels", group="Display")

// Reset lines on new day
var daily_open_line = line.new(na, na, na, na, width=line_width, color=daily_open_color, extend=extend.right)
var prev_close_line = line.new(na, na, na, na, width=line_width, color=prev_close_color, extend=extend.right)

// Reset labels on new day
var daily_open_label = label.new(na, na, "", style=label.style_label_left, color=color.new(color.white, 100), textcolor=daily_open_color)
var prev_close_label = label.new(na, na, "", style=label.style_label_left, color=color.new(color.white, 100), textcolor=prev_close_color)

// Check if it's a new day
is_new_day = ta.change(time("D"))

if is_new_day
    // Update the daily open line
    if show_daily_open
        line.set_xy1(daily_open_line, bar_index, daily_open)
        line.set_xy2(daily_open_line, bar_index + 1, daily_open)
        
        if show_labels
            label.set_xy(daily_open_label, bar_index, daily_open)
            ticker_prefix = show_ticker_info and custom_ticker != "" ? custom_ticker + " " : ""
            label.set_text(daily_open_label, ticker_prefix + "Daily Open: " + str.tostring(daily_open, format.price))
    
    // Update the previous day close line
    if show_prev_close
        line.set_xy1(prev_close_line, bar_index, prev_day_close)
        line.set_xy2(prev_close_line, bar_index + 1, prev_day_close)
        
        if show_labels
            label.set_xy(prev_close_label, bar_index, prev_day_close)
            ticker_prefix = show_ticker_info and custom_ticker != "" ? custom_ticker + " " : ""
            label.set_text(prev_close_label, ticker_prefix + "Prev Close: " + str.tostring(prev_day_close, format.price))

// Plot the levels for debugging (can be hidden)
plot(show_daily_open ? daily_open : na, "Daily Open", color=daily_open_color, style=plot.style_circles, display=display.none)
plot(show_prev_close ? prev_day_close : na, "Previous Day Close", color=prev_close_color, style=plot.style_circles, display=display.none)``
