Very long term for investment

When I look that old quarterly ECU and Euro charts, I have noticed that there is a working uptrend. If same movements will occur again we will see 1.8 levels in the very long term I think. Also we can see that similar monthly movements are continuing. The key point is technical analysis may not work in this very long date range. I will plan my trades with this possibility.
