TWAP & VWAP Combined

This script integrates Time Weighted Average Price (TWAP) and Volume Weighted Average Price (VWAP) into a single TradingView indicator, allowing traders to analyze both price-weighted and volume-weighted trends simultaneously.

Features:
TWAP Calculation:

Computes the average price over a specified anchor period (e.g., daily).
Resets and recalculates TWAP when the anchor period changes.
Uses the OHLC4 (Open, High, Low, Close average) as the default price source.
VWAP Calculation:

Computes the VWAP based on the selected anchor period (Session, Week, Month, etc.).
Allows the option to hide VWAP when the timeframe is 1D or higher.
Uses HLC3 (High, Low, Close average) as the default source.
Dynamically resets VWAP at the start of a new period.
Customization Options:

Users can modify the source price for TWAP and VWAP calculations.
Adjustable offsets for both indicators to shift plots forward or backward.
Ability to select different VWAP anchor periods, including earnings, dividends, and splits.
Error Handling:

Displays an error message if volume data is missing, ensuring VWAP functions correctly.
