DAILY MARK-TO-MARKET
What the portfolio did each day.
Daily P/L removes new contributions, so it shows market movement rather than deposits. QQQ’s last close carries through weekends and holidays.

Simple rules.
Visible assumptions.
This is an educational simulation, not financial advice. Purchases are fractional and use published BTC/USD and QQQ reference prices. Daily P/L excludes new contributions. Fees, spreads, slippage, taxes and QQQ dividends are excluded.
