Timeline, Averaging, Defending, and Optimising — built around your actual completion date, shared with your estate agent, notaire, and the seller, not a guess.

A single conversion on one day is a gamble dressed up as a decision. Posydonia gives you a strategy built around when your deal actually completes.
Deals like these have several parties working off different calendars. Start a shared timeline, send the link to your estate agent, notaire, and the seller, and let each of them add the dates as they're confirmed — no account needed on their end. This one dataset — currency pair, target rate, and the timeline — is what drives Averaging, Defending, and Optimising; nothing gets re-entered.
Instead of converting the full amount on one date, Posydonia splits your transfer into scheduled tranches across the weeks leading up to completion — so no single day's rate decides your outcome.
Track the live rate against the target you set on your timeline, get alerted the moment it's hit, and lock the full amount in one tap — or fix a forward rate now for a date up to 12 months out.
Posydonia models the expected rate trend across your specific time gap, with a confidence band that widens the further out you look — so you can see whether the market favours moving early, waiting, or splitting the difference.
