DAYE Session Levels QUARTERLY THEORY– M15, H1, H4

📊 Indicator: Previous Session Max/Min Close Levels
🔍 Overview
This indicator displays the highest and lowest closing prices from the previous session across three key timeframes (H1, H4, M15). It is inspired by the Daye Quarterly Theory, which divides time into cyclical quartiles. These levels act as potential support/resistance zones where price often reacts.

🧠 Theoretical Foundations
Daye Quarterly Theory – Time-Based Market Structure

Monthly cycle: divided into 4 weeks, with the True Open on the second Monday (Q2).

Weekly cycle: divided into 4 days (Mon–Thu), with the True Open on Tuesday (Q2).

Daily cycle: divided into 4 sessions of 6 hours each, based on New York time:
-Q1: Asia (6 PM – 12 AM NY)
-Q2: London (12 AM – 6 AM NY) → True Daily Open
-Q3: New York (6 AM – 12 PM NY)
-Q4: PM Session (12 PM – 6 PM NY)

The indicator uses this time-based logic to calculate significant levels based on strong closes in previous sessions.

⚙️ Indicator Functions
✅ 1. Historical Levels (default mode)
Displays persistent horizontal lines at the high/low close of the previous session:
- H1: last 25 candles (1 day)
-H4: last 31 candles (1 week)
-M15: last 25 candles (6-hour session)

These levels are always visible and are drawn as thin black lines, helping traders recognize historically significant price zones.

🆕 2. Current Session Levels (optional)
When enabled, this mode shows the same previous-session high/low close only during the current session.

The levels:
-start exactly at the candle where the max/min close was registered in the previous session;
-extend up to the end of the current session;
-are automatically reset at the beginning of each new session.

These dynamic levels help monitor how price behaves around recent key zones in real time.

🧰 Custom Settings
The indicator includes two toggles:
-Show Historical Levels – enables/disables persistent previous-session levels.
-Show Current Session Levels – enables/disables live levels that appear only during the current session.

You can use either one or both simultaneously.

🧠 Ideal Use Cases
This tool is perfect for traders who:
-work with intraday or swing trading strategies;
-rely on support/resistance, market structure, or liquidity zones;
-want to identify where reversals, continuations, or breakouts are most likely;
-follow time-based cycles for confluence in execution.

📌 Final Thoughts
A simple yet powerful indicator that blends temporal cycles with price behavior, allowing traders to stay aligned with meaningful levels as markets evolve. Designed to provide clarity, structure, and precision for both discretionary and systematic trading.
