Vectorvest would be a much more reliable system if you could buy at historical rt lows and sell at historical rt highs because the historical rt highs and lows (even if you go out 10 years) particularly with etfs all form a nice range. These historical rt highs and lows repeat themselves time and time again and create a way to "see the future"
For example rt in spy write now is 123. For example rt highs with spy range from 139 (one time) and most of the rt highs range at a median of 123.5 maxing out at 126. So now is a great time to dollar cost average INTO SHORTING THE MARKET not buying into it. RT is a much better indicator of long term market movement than the buy and hold recommendations on the graph. So I need a tool to find stocks and ets that are currently within 3-5 percent of their historical rt highs and lows.
