OPEN-SOURCE SCRIPT
ORB + Key Levels (PDH/PDL, PM H/L, PDC, Open)
Restructured for backtesting. The key change: instead of drawing only the current day's rays at the last bar, the script now creates real line objects day by day as it processes history. So:
Every past day on the chart keeps its own ORB 15/30, PDH/PDL, PDC, PM H/L, and opening print lines — each one starting at its forming candle and ending at that day's close
When you enter bar replay mode and jump to any date, the script recalculates up to the replay point, so that date's levels are drawn correctly and the "active" day at the replay head extends to the right edge — exactly like live trading
As you step forward through replay, ORB lines pop in the moment the 15/30-min window completes (9:45/10:00 ET), PM levels update tick-by-tick during premarket, and everything freezes when the next day's premarket begins — so you're seeing exactly what you'd have seen in real time, with no lookahead
Two practical notes for your replay testing:
Line history depth: max_lines_count=500 keeps roughly the last 50 sessions of lines visible (10 lines per day). TradingView's hard cap is 500, so older days silently drop their lines — but in replay this doesn't matter, since everything recalculates from the replay point anyway.
On the very first day of loaded history there are no PDH/PDL/PDC lines (there's no tracked previous day yet) — start your replay at least one session in.
