ORIGNAL INDICATOR Yesterday's open, high, low and close BY EduardoMattje AND FULL CREDIT TO HIM
I have only modified with 2 changes
1.Now yesterdays levels are visible from very first candle of any small time frame
2/Labels are also visible of OHLC so it removes confusion for trders

What it does:

Plots yesterday’s Open, High, Low, and Close as horizontal lines on any timeframe (1min, 5min, hourly, daily, etc.).
Lines automatically extend to the right edge of the chart (until the current day ends).
Shows permanent labels on the far right with short prefixes:
O = Yesterday’s Open
H = Yesterday’s High
L = Yesterday’s Low
C = Yesterday’s Close

Key features:

Works perfectly in regular and extended (pre/post-market) sessions
Option to hide the levels on previous days (keeps chart clean)
Very lightweight and fast
No compilation errors

Perfect for day traders who want yesterday’s key levels always visible with clear O/H/L/C labels on the right side of the screen. Just add it once and forget – it updates automatically every day
