➕ Adding a Currency Pair

A pair tells LibreFolio where the rate between two currencies comes from: a central bank provider, a chain of providers, or rates you enter yourself.

Click Add Pair on the FX page. The same window opens from the Dashboard, from an asset page and from the FX step of the PAC allocator.

🧭 Add a pair step by step

💱 Step 1: Pick the two currencies

In Add New Currency Pair, choose the Base Currency and the Quote Currency. Each list hides the currencies already paired with the other one, so a pair cannot be added twice.

🛤️ Step 2: Choose a route

Click Add conversion route to see every way the providers can produce this rate:

  • 🔗 Direct conversion (1 step) — one provider publishes the pair;
  • 🔀 Chain conversion — steps through other currencies, grouped by number of steps;
  • 🚫 Not usable — providers that cannot reach this pair.

Filter with the search box (provider, currency or country), then click a route to add it.

Add Pair — Direct Routes Add Pair — Chain Routes
🛟 Backup routes — when you add more than one

LibreFolio uses route #1 first and tries #2 if it fails during a sync, and so on. Drag the routes to reorder them; 🗑️ removes one, and ⚠️ shows a note from its provider.

🔀 Also create intermediate pairs — when you pick a chain route

Tick Also create intermediate pairs to save each step as a pair of its own. You can then sync each step separately and convert into the intermediate currency too: a chain stores only the rate of its own pair.

✏️ No route — manual rates only

You can save without a route, then enter the rates yourself in the pair's Data Editor.

💾 Step 3: Save

Click Save Configuration; the window closes right away.

  • With a provider, LibreFolio downloads the pair's whole history up to today, whatever period the page shows, intermediate pairs included. A message reports the result, in green only if everything worked.
  • Without a provider, a message confirms that the pair was created.

Click the pair's name in the message to open its page.

🛤️ Direct and chain routes

A direct route uses one provider that publishes both currencies, such as the ECB for EUR 🇪🇺 / USD 🇺🇸. When no central bank publishes the pair, a chain route multiplies the rates of its steps. RON 🇷🇴 / USD 🇺🇸, for example, goes RON → EUR → USD, both steps from the ECB, which publishes EUR/RON and EUR/USD:

\[ r_{\text{RON}\to\text{USD}} = r_{\text{RON}\to\text{EUR}} \times r_{\text{EUR}\to\text{USD}} \]
  • A chain has a rate only on the days when every step has one.
  • If one step fails during a sync, the whole chain fails: shorter chains are more reliable.
  • A chain rate can differ slightly from a direct market quote.
