By considering the behaviour of index time series
a strategy against the trend is proposed based
on a three-days close price indicator. The chances
of market countermotions after qualified growth
and decay periods are studied for DAX and
DAX-Future data. A simulation of geometric
Brownian motion shows the difference to real index
time series.
