Price Range Deviation

📌 Description: Price Range Deviation Indicator
This indicator measures how much a stock has moved over a recent period (e.g., 15 days) and compares that move to the average move of similar-length windows over a longer lookback period (e.g., 1 year or 252 days).

It helps identify when a stock has made an unusually large move compared to its historical norm — which can signal that the move is overextended.

📊 How It Works:
Recent Move ($): The absolute price change over the selected recent period.

Average Move ($): The average absolute price change over rolling windows of the same size across the full lookback period.

Move Ratio: The current move divided by the average move.

When the move ratio exceeds a custom threshold (e.g., 1.5× the average), the background highlights red to signal that the move is unusually large.

💡 Use Case:
Ideal for options traders looking to:

Identify overextended price moves

Sell out-of-the-money calls or puts beyond a high-move zone

Fade price exhaustion with high probability setups
