How are my holdings converted to my home currency?

In two steps, and in that order. First each holding is valued in the currency it is really in — units × the latest close for a listed holding, the figure you typed for anything else. Then that value is converted into your plan’s currency at the day’s exchange rate, once, before any total, reading or projection is worked out. Your plan’s currency — the home currency every figure is reported in — is set by the country you will be living in once you are independent.

Why the order matters

• Nothing is frozen at an old rate. A holding is stored in its own currency, so when the rupee or the dollar moves, its value in your plan moves with it the next morning, without you editing anything.
• Every page agrees. The Portfolio Tracker, the FIRE Planner, the Freedom Ladder and the Overview all read the same converted figures.
• A London quote in pence is read as pence. Many London-listed lines are priced in pence; Nivritee turns those into pounds before converting, so nothing reads a hundred times too large.

The rates, and the checks on them

• Exchange rates refresh once a day, before the overnight readings are recalculated.
• A pegged currency, such as the dirham, must stay within 0.5% of its peg.
• A currency the European Central Bank publishes must agree with it to within 2%.
• Any other move of more than 10% in a day is held until the next day’s rate repeats it.
• A rate that fails a check is not used; the last accepted rate is kept, and a rate older than 14 days says so.

The Portfolio Tracker names both dates it used — Prices as of and exchange rates as of — under its headline. A currency with no rate at all stays in its own units with a notice, rather than being dropped or counted as zero.
