Multi-currency portfolio tracker: USD, EUR and TRY in one total

5 min read · Updated October 20, 2026

A multi-currency portfolio tracker keeps assets priced in different currencies in one record and adds them up with the day's exchange rate. This guide shows how Alphanta does that and how to read the currency effect in your own numbers.

How the multi-currency portfolio tracker works

Alphanta is record-keeping software. You tell it what you already own; it prices those holdings, converts them and shows the total. It does not trade, it does not hold money and it does not give advice.

Under the hood every value is kept against one base currency, the US dollar. Holdings priced in dollars, such as a total-market ETF held at a US broker, are used as they are. Holdings priced in Turkish lira, such as a Turkish mutual fund, a pension (BES) fund or a share listed in Istanbul, are read at their lira price and converted with the day's USD/TRY rate. That is what lets a lira fund and a dollar ETF sit in the same total.

The conversion runs again every day. Your total reflects the latest rate Alphanta has, not the rate on the day you bought.

Record each holding in its own currency

How you enter a holding depends on its type. A few rules keep the record clean:

• Shares, ETFs and funds: enter the quantity and the purchase price. In the add-holding form the purchase price is in US dollars, so for something you paid for in lira, enter its dollar amount on the purchase date. Your cost and today's value then sit in the same currency.
• Turkish mutual and pension funds: choose the fund type and the fund code. Alphanta reads the lira price and converts it for you.
• Cash: enter the amount in US dollars.
• Rental property: enter the property value and the monthly rent, either in lira or in dollars. If you choose lira, Alphanta converts the value with each day's rate, so the property moves with the exchange rate even when its lira value stays the same.
• Bonds: enter the nominal amount in US dollars, the price as a percentage of nominal, the coupon rate and the maturity date.
• Interactive Brokers positions: they arrive through a read-only Flex Query import, with the currency IBKR reports for each position.

Choose the currency you want to see

Your records stay in their own currencies, but you decide how the total is shown. The display currency switch offers USD, EUR and TRY.

Switching changes only the presentation. It does not rewrite purchase prices or any other record, so you can move between currencies as often as you like.

1. On desktop, scroll to the bottom of the side menu. The display currency switch sits next to the language switch.
2. On mobile, tap More. The switch is in the same place as the language setting.
3. Pick USD, EUR or TRY. Totals, allocation amounts and income figures are then shown in that currency, converted with the day's rate.

Read the exchange-rate effect

When a holding's currency and your display currency differ, part of every change in value comes from the exchange rate. A worked example with sample numbers makes this clear.

Say you hold a lira fund worth 100,000 TRY and the sample rate is 40 TRY per dollar. In dollars the fund is worth 2,500. A month later its lira price has not moved, but the sample rate is now 42. The same fund is worth about 2,381 dollars. Nothing happened to the fund; the lira simply buys fewer dollars.

Now flip the view. Shown in TRY, that fund stays at 100,000, while a dollar-priced holding worth 2,500 dollars rises from 100,000 to 105,000 TRY. Same records, different lens.

If you think in euros, the logic is the same. Shown in EUR, your total absorbs the moves of both the lira and the dollar against the euro, so in the same month your dollar total can fall while your euro total rises. Both are correct; they simply measure with a different ruler.

Keep this in mind when you read Value history, the daily record of your portfolio total. Alphanta stores those daily totals in US dollars, so a move in the lira or the euro appears in your history even on days when your holdings did not change. These numbers are a record of what happened, not a forecast.

Move data in and out with CSV

Your records are portable. To export, open Settings → Portfolios and use Export CSV in the Export holdings card. The file lists every holding with these columns: portfolio, symbol, name, type, quantity, purchase_price, purchase_currency, current_price and created_at. Open it in any spreadsheet to keep your own archive or to check figures.

The CSV importer reads columns such as symbol, name, shares, cost basis and type, plus an optional dividend yield column. Costs in an imported file are read as US dollars, so convert lira or euro costs before you import.

A short monthly routine

A few minutes once a month keep the record honest:

1. Add new holdings and update quantities after you buy or sell elsewhere.
2. Check that lira-priced items show a current price. A missing price usually means the fund or share code needs a second look.
3. Look at the total in the currency you think in, then switch to a second currency to see how much of the month's change came from exchange rates.
4. Export a CSV copy for your own files.

Questions

Can I keep assets in different currencies in one portfolio?

Yes. Holdings priced in US dollars and in Turkish lira can sit in the same portfolio. Alphanta converts lira prices with the day's USD/TRY rate and adds everything to one total.

Does changing the display currency change my purchase prices?

No. The display currency only changes how totals are shown. Purchase prices and every other record stay exactly as you entered them.

Where do the exchange rates come from?

Alphanta uses a daily rate from a third-party price source. Rates can be delayed, so treat converted totals as a record of your holdings, not an official valuation.

Can I export my holdings?

Yes. Settings → Portfolios → Export CSV downloads every holding, including its purchase currency.
