Formula used
- Percent fee (USD) = Amount × (Fee% ÷ 100)
- Total fees (USD) = Percent fee + Fixed fee
- Net invested (USD) = Amount − Total fees
- Effective price (USD) = Market price × (1 + Slippage% ÷ 100)
- BTC bought = Net invested ÷ Effective price
- Cumulative BTC = Σ BTC bought
- Cumulative invested = Σ Net invested
- Average cost (USD/BTC) = Cumulative invested ÷ Cumulative BTC
- Portfolio value (USD) = Cumulative BTC × Current BTC price
- Unrealized P/L (USD) = Portfolio value − Cumulative invested
