Your answer will appear here.
Help and method
Sum each quantity × price plus its fees; divide by total quantity. Purchase-only average; not a tax-lot method. Hypothetical local calculation. Use one currency for all amounts; the currency selector changes formatting only. No live quotes, taxes, trade execution or investment advice. Fees are per transaction. Negative projections are possible. Displayed amounts may be rounded. Keep full quantity and unit-price precision; a rounded target price may miss the requested profit.
