Key Levels
Here's a publication description you can drop into TradingView:

**Key Levels + Battle Line**
A clean intraday levels indicator that maps the day's most-watched price reference points and identifies the central level bulls and bears are fighting over.
At the 9:30 cash open, the script locks in and plots seven key levels, each extending fully across the chart:
- **Premarket High / Low** — the range built before the open
- **Yesterday's High / Low / Close** — prior-session reference points
- **Premarket Mid** and **Yesterday Mid** — the equilibrium of each range
It then calculates a **Battle Line** — the central pivot of the whole structure. You can set this to either the *range equilibrium* (midpoint between the highest and lowest key level) or a *5-level average* (mean of premarket high/low and yesterday's high/low/close), which behaves more like a center-of-gravity pivot. The idea is simple: price tends to chop around this line while neither side has control, and a decisive break tends to resolve in that direction.
When price closes through the Battle Line, the indicator marks the break with an arrow and flips the directional bias — close above for bullish, close below for bearish. By default, breaks are confirmed on the bar **close** rather than wicks, so you're reacting to commitment rather than noise. An optional background shade colors the session by current bias, and built-in alerts fire on each break.
**Settings**
- Fully adjustable premarket and regular session times plus timezone (default 9:30 = US cash open)
- Toggle any level on or off
- Custom colors, line widths, and label offset
- Choose the Battle Line basis and switch break confirmation between close and wick
- Optional break arrows and bias background shading
**Notes**
- Designed for intraday timeframes; built and tested on 15-minute charts
- Yesterday's values are pulled from the daily timeframe
- Levels anchor at the open, so load a recent regular-session day to see them
This is an analysis tool, not financial advice. Always confirm setups with your own plan and risk management.
