NY Session 15 min ORB + Fib RetracementThis indicator builds a New York session Opening Range (ORB) and plots Fibonacci retracement levels based on that range.

Tracks the ORB high and low during that window
Locks the ORB once the window ends (recommended)
Draws Fibonacci retracement levels from the ORB range
Optionally fills the space between fib levels
Displays price tags for ORB levels and fib levels on the right side
Sessions
ORB window is configurable (default: 9:30–9:45 ET)
Fib levels are only shown during the selected plot session
(default: 9:30–16:00 ET)
