The direction of travel is clear. A reversal will be clear if and when it comes.
The interesting thing about this chart is that normally the DOW does a little retrace and consolidates itself each 1000 points. It's not done that at 23k (yet) so we may get a little pull back OR it might well skip this round of consolidation and head straight to 24000 which was what happened this time last year when it skipped 19 to go straight to 20 and then take the consolidation into 2018.
Either way, buy a dip and keep adjusting the stop Loss is the best strategy for the DOW, SPX , NDX, DAX etc. You will make a lot more money buying the rises than betting on a single massive fall.
