Results and examples
Ten shares at KRW 1000 and twenty at KRW 1500 total thirty shares costing KRW 40,000, for an average near KRW 1333.33. The simple midpoint of the two prices, KRW 1250, would be wrong.
Limitations
- Sales, splits, dividends and foreign-exchange changes are not applied automatically.
- Omitted commissions and taxes can make the result differ from an official tax basis.
