What's interesting is to compare this to the trend signals in individual stocks, for instance, take $TSLA, it has a signal indicating it may rally until 2023, and reach a price as high as 5000 or close to it.
Another interesting thing is to try and adjust the $DJI to , which at times helps explain inconsistencies in certain chart signals time duration (I've observed this in $TRV for example, if we don't adjust it to , long term trend duration is a bit off).
It's good to verify both charts to be safe.
Here's the adjusted chart:
In this case the bull market duration is a bit longer in the yearly.
The 2 month timeframe works well for mid term swings, in both charts:
