Looking at history, reseach shows that stockmarkets could be far away from their end to current downturn. It seems that the October 01st 2018 top was spot on for now.
The graph below gives you the perspective. In February of 1966 the DJIA and DAX started trending down to bottom around the new year of 1967. In late October of 1973 DJIA and the DAX indices started the downturns ending in October of 1974.
Putting these downtrends into perspective, there are now between 154 and 189 intradays to go from present levels until markets could see their low points. These are marked with RED dots in the chart below.
By continuing to follow the DJIA path for 1973 into 1974, markets should not rule out prices - 30% lower than present levels this October of 2019 for thereby to be retested in December.
