Trendline Dynamics is an informative weekly newsletter that I follow by 30-year technical analyst Richard (Doc) Ahrens who provides a macro view and  objective market analysis.  (Doc was a student of Ken Long's courses.) 

Methodology: Every week Trendline Dynamics scans several ETF universes to identify ETFs which are in a rising trend and have reached a buy level. It also looks at which ETFs have reversed from rising to falling. The ETFs span a range of asset classes including global equities, bonds, and commodities throughout all phases of market cycles. The intent is to dynamically allocate to productive asset classes and reduce exposure to those that are non-productive. Some people jump to the conclusion that dynamic asset allocation is the same as market timing. Market timing relies on making predictions about the future. We do not try to predict anything. We listen to what the market is telling us and use rigorous exit discipline to limit risk. Avoiding losses is the foundation of this strategy. We continually monitor each ETF's current trend using our exclusive combination of public and proprietary indicators. Our adherence to exiting as soon as the reward-to-risk ratio falls below 1  trims our losses, and we let the profits take care of themselves.
