NYMO Alert

Overview

The NYMO Alert is a comprehensive TradingView indicator designed around the "New York Midnight Open" (NYMO) concept. It tracks the price level at midnight (00:00) in the selected timezone (default: America/New_York) and monitors price behavior during key pre-market and early-session windows to determine range balance.
At exactly 7:00 AM, the indicator issues a non-repainting alert indicating whether the range is BALANCED (midnight open revisited between 3:00–7:00 AM → no retracement expected) or IMBALANCED (midnight open not revisited → expect retracement to the midnight level during the 8:30–11:00 AM window).
Key Features

During the 3:00–7:00 AM observation window, checks if price touches or crosses the midnight open level.
At 7:00 AM, evaluates the status and triggers the appropriate alert.
Visual elements update dynamically and support multiple historical days.
