Disposals
Per-disposal breakdown with FIFO matching.
How to read this: the Disposed date is the taxable event (it determines the tax year). The Acquired date is the FIFO lot you originally bought - it sets your cost basis and your holding period. Lots from prior years are normal and expected; only disposals dated in your selected tax year count toward this year's totals.
| Asset | Acquired (cost basis date) | Disposed (tax event) | Quantity | Cost basis | Proceeds | Gain / loss | Class |

Methodology note. Calculations use FIFO matching, the most common method accepted by tax authorities worldwide. UK same-day / bed-and-breakfast / Section 104 pool rules ship in the next iteration; the UK option currently falls back to FIFO with a warning.
