BTC ETFs AUM

📘 Description: BTC ETFs AUM Tracker

This indicator tracks the Assets Under Management (AUM) and daily inflows/outflows of the main U.S.-listed Bitcoin ETFs, allowing you to visualize institutional capital movement into Bitcoin products over time.
It uses official financial statement data provided by TradingView’s request.financial() function.

🧩 Overview

The script adds up the daily AUM changes from selected Bitcoin ETFs to estimate the total net inflow/outflow of capital into spot BTC funds.
It also accumulates those flows over time to display the total aggregated AUM balance, giving you a clearer sense of market direction and institutional sentiment.

Two display modes are available:

Balance view: plots the cumulative sum of net inflows (total ETF AUM).

Inflows view: shows daily inflows (green) and outflows (red) as histogram columns, together with a smoothed moving average line.

⚙️ Inputs Explained
Base Settings

Base Multiplier (base_multi) – Scaling factor applied to all AUM values. Leave at 1 for USD units, or adjust to display values in millions (1e6) or billions (1e9).

Smoothing (c_smoothing) – Period length for the simple moving average used to calculate the smoothed mean inflow/outflow line.

Show Balance (showBalance) – When enabled, displays the total cumulative AUM balance (sum of all net inflows over time).

Show Inflows (showInflows) – When enabled, displays the daily inflows/outflows as colored columns.

ETF Selection

You can toggle which ETFs are included in the calculation:

• IBIT (BlackRock)
  
• GBTC (Grayscale)
  
• FBTC (Fidelity)
  
• ARKB (ARK/21Shares)
  
• BITB (Bitwise)
  
• EZBC (Franklin Templeton)
  
• BTCW (WisdomTree)
  
• BTCO (Invesco Galaxy)
  
• BRRR (Valkyrie)
  
• HODL (VanEck)
  

Each switch determines whether the ETF’s AUM and daily flow data are included in the total calculation.

📊 Displayed Values

Green Columns → Positive daily net inflows (AUM increased).

Red Columns → Negative daily net outflows (AUM decreased).

Orange Line → Smoothed moving average of net flows, used to identify persistent inflow/outflow trends.

Blue Line (if enabled) → Total cumulative AUM balance (sum of all historical flows).

💡 Usage Notes

Works best on daily timeframe, since ETF data is typically updated once per trading day.

Not all ETFs have identical data history; missing data points are automatically skipped.

The indicator doesn’t represent official fund NAV or guarantee data accuracy — it visualizes TradingView’s public financial feed.

You can combine this tool with price action or on-chain metrics to analyze institutional Bitcoin flows.
