"On 1 January 1999, 11 EU member states acquired a single currency, the euro. This was achieved by locking the exchange rates for the legacy currencies of the participating EU member states (euro area member states) vis-à-vis the euro. For the first three years, the euro existed only as electronic money, while the legacy currencies still existed as banknotes and coins. However, the fixed parities of the 11 legacy currencies vis-à-vis the euro meant that they were no longer independent currencies, and consequently they were no longer traded in the currency markets".
So unless you are calling adding countries like Slovenia, (sorry de123) Slovakia and Cyrpus as major events. I think the above is what matters when discussing the euro rollout.
Next now look at your chart and see which direction it went first after '99. Did it go up? It did once it bottomed for the last time in '02. Went on a tear till '08 and has given back half. So I guess you could say that is ok depending on when someone went short or long. The question now is whether or not it will go further down or resume long term uptrend.
I don't know about you but I don't trade such long term periods so all it means is bragging rights, which mean nothing to me. All I care about is that the market move and trade it whichever way it goes.
