To lose £31 pounds i.e. from £900 to £869, the exchange rate must have moved from 0.70104 euros to the pound. (or 1.4264 euros to the pound)
i.e. when you changed 900 to euros you got 900 / .70105 = 1,283.79 euros.
Looking at the yahoo exchange rate graph
British Pound to Euro Exchange Rate - Yahoo! Finance
You must have sold the domain exactly on the 1st April (april fool's day) and then had the money transferral take not 2 days, but until the 1st August until this exchange rate has gone against you to that extent.
You would have also been very unlucky to have caught the years low of the euro.
So you are a) extremely unlucky having sold the domain on that date. (the lowest value of the year)
b) extremely unlucky in that the money transfer took 4 months
c) extremely unlucky that the exchange rate moved the most it had moved all year in the opposite direction to your position during that 4 months.
Hard luck.
