📍 Strike Tracker (Current Option Strike Price)

This indicator is designed for options traders who want to visually track the current strike price based on the price of the underlying stock or ETF — but only when the price fully crosses into a new strike level.

Unlike typical midpoint rounding methods, this version uses ceiling logic:

The strike line stays at the current level until price equals or exceeds the next strike step.

For example, with a 0.5 interval:

Price = 85.74 → strike remains 85.5

Price = 86.00 → strike moves to 86.0

⚙️ Key Features:
Automatically tracks strike levels based on configurable intervals (e.g., 0.5, 1.0, 2.5, etc.)

Strike line only updates once price crosses the threshold

Dynamic label showing the current strike

Works in real time on any stock, ETF, or futures chart

🧪 Ideal For:
Traders managing ATM (At-The-Money) or rolling strike options

Traders using TradingView charting to quickly visualize when to adjust strikes

Traders who want to avoid premature strike shifts from midpoint logic

📌 How to Use:
Load the indicator on the chart of the underlying (e.g., TLT, SPY, AAPL)

Set the correct strike interval (e.g., 0.5 for TLT, 1.0 for SPY)

Watch the strike line update only when price has fully moved into a new bracket

❗ Do not apply this script to option symbols (like TLT250711C85.5) — it must be used on the base chart (e.g., TLT) to function correctly.
