Key Levels & Sessions
This is a professional-grade institutional key levels indicator designed for day traders who focus on session liquidity and high-volume price levels. The script provides a comprehensive view of the trading day by marking critical boundaries and institutional reference points, all strictly synchronized to the **America/New_York** (EST) timezone.
### **Key Features:**
#### **1. Institutional Daily Levels**
* **Previous Day High (PDH) & Low (PDL):** Marked with solid purple lines, these represent the most basic yet powerful liquidity levels from the prior trading day.
* **Previous Day Point of Control (POC):** A solid white line calculated using a Volume Profile algorithm. It identifies the price level where the most trading activity occurred during the previous session, acting as a "magnet" for price.
#### **2. Global Session Ranges**
* **Asia Session (8:00 PM - 2:00 AM EST):** Plotted in orange. This captures the initial range of the global trading cycle.
* **London Session (4:00 AM - 9:30 AM EST):** Plotted in blue. This identifies the volatility often seen during the European open leading into the New York session.
#### **3. New York 15-Minute Opening Range (ORB)**
* **ORB Box:** Automatically captures the high and low of the first 15 minutes of the New York session (9:30 AM - 9:45 AM EST).
* **Midline Projection:** Features a yellow dashed midline within the ORB box, a critical level often used by traders to determine intraday bias.
#### **4. Dynamic Projection & Cleanup**
* **Extension to Market Close:** Once established, every level (Asia, London, ORB, and PD levels) automatically projects forward to the **5:00 PM EST market close**.
* **Automatic Reset:** To keep your workspace clean and professional, the indicator utilizes an object-tracking system that deletes all drawings from the previous day at exactly 5:00 PM EST, allowing the chart to "reset" for the new Asia session.
* **Right-Anchored Labels:** All levels are clearly labeled on the right side of the chart, ensuring identification is instant without interfering with live price action candles.
### **How to Use:**
This tool is best used on **lower timeframes (1m to 15m)**. Traders often look for price to react at these levels—either as support/resistance or as "liquidity grabs" where price sweeps a session high/low before reversing. The NY ORB box provides a clear breakout or mean-reversion zone for the morning trend.
