You should try this :

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

indexHighTF = barstate.isrealtime ? 1 : 0
indexCurrTF = barstate.isrealtime ? 0 : 1
yesterday_close = request.security(syminfo.tickerid, "1D", 
close[indexHighTF])[indexCurrTF]
daily_line = line.new(bar_index, yesterday_close , bar_index-1, yesterday_close, extend= extend.both, color=color.yellow)
line.delete(daily_line[1])

It is based on the pinescript manual , see here : https://www.tradingview.com/pine-script-reference/v5/#fun_request{dot}security
