IV History from Realized Volatility

4시간 전

# Realized Volatility History - Quick Start Guide

## What This Does
Displays historical realized volatility (RV) calculated directly from price movements. Compare it against your current implied volatility to identify options trading opportunities and gauge whether premium is expensive or cheap.

## How to Use

1. **Get Current IV**: Check your broker's options chain and find the ATM (at-the-money) implied volatility for your ticker

2. **Input the Value**: Open indicator settings and enter the current IV (e.g., `0.15` for 15%) - this creates a reference line

3. **Read the Chart**:
- **Purple line** = Historical realized volatility from actual price movements
- **Red dashed line** = Your current ATM IV (reference)
- **Orange line** = 30-day moving average (optional)

4. **Interpret the Data**:
- **RV below IV** → Options premium is relatively expensive (consider selling premium)
- **RV above IV** → Options premium is relatively cheap (consider buying options)
- **IV Rank > 70%** → High volatility environment
- **IV Rank < 30%** → Low volatility environment

## Settings You Can Adjust
- **Current ATM IV**: Reference line for comparison (update periodically)
- **RV Rolling Window**: Calculation window for realized volatility (default: 10 days)
- **Lookback Period**: Period for IV rank calculation (default: 60 days)
- **Show 30-Day Average**: Toggle moving average line

## Limitations
This indicator requires manual IV updates since TradingView doesn't have direct access to options data. You'll need to check your broker periodically and update the input for accuracy.
