Cumulative Moving Average (Anchored)

Title:
Cumulative Moving Average (Anchored) – Timeframe & Source Flexible Trend Analysis

Description:
The Cumulative Moving Average (Anchored) provides an anchored view of price averages, accumulating values from a user-defined start time. This approach emphasizes long-term trend context while allowing flexible timeframe and price source selection, helping traders identify the cumulative effect of price action over a specified period.

Key Features:
• Anchored Averages: Starts accumulation from a custom date/time to analyze long-term price trends.
• Multi-Source Support: Choose from Close, Open, High, Low, HL2, HLC3, OHLC4, or High & Low for versatile analysis.
• Higher-Timeframe Support: Optionally calculate averages using a higher timeframe while plotting on the current chart.
• Separate High/Low Averages: When using "High & Low" mode, displays cumulative high and low averages to visualize the price range evolution.
• Lightweight & Transparent: Simple cumulative logic keeps charts clear and responsive.

Inputs & Settings:
• Calculation Timeframe (default = chart timeframe)
• Start Date / Time for anchored averaging
• Source selection for price calculation (Close/Open/High/Low/HL2/HLC3/OHLC4/High & Low)

Usage:
This indicator helps traders:
• Observe long-term trend behavior anchored from a specific date
• Compare cumulative high and low trends against price action
• Confirm trend direction over custom periods for strategy alignment
• Integrate anchored averages into multi-timeframe analysis

Technical Notes:
• Start time defines the beginning of cumulative calculation; resetting requires adjusting the date/time input. (click 3 dots next to indicator, select re-set points)
• Works best on standard OHLC charts; non-standard chart types may yield inconsistent results.
• Past trends do not guarantee future performance; always apply proper risk management.
