Trding Session Levels + Pre-Market H/L
A clean, visual mapping tool for intraday session structure.
Marks pre-market, regular (RTH), and after-hours session boundaries
with vertical dashed dividers, then plots the pre-market High and
Low as horizontal reference lines that extend through the regular
session. Also draws an opening-range High/Low (first N minutes of
RTH · default 30 min) and yesterday's close as reference lines.
FEATURES
- Vertical dashed dividers at pre-market open, RTH open, RTH close,
and after-hours close (each independently toggleable)
- Pre-market High and Low lines · captured during pre-market,
frozen at RTH open, held through RTH close
- Opening-range High/Low · configurable window (1-120 minutes)
- Yesterday's close reference line
- Configurable timezone (America/New_York default · 6 zones supported)
- Full brand palette · matches the rest of the Trding.ai script family
HOW TO USE
1. Set your timezone (default America/New_York for US equities)
2. Toggle which session dividers and reference lines you want visible
3. Adjust the opening-range window if 30 min isn't your rhythm
Pairs naturally with any VWAP, ATR-based risk planner, or entry
system. Educational only · not financial advice · does not generate
buy/sell signals.
