Best way to measure market pullbacks ...Income signal

Income signal
One of my favorite technical analysis strategies and one I often recommend traders start off with is the 4×4 strategy. Works well for high volume stocks and index futures. 

4x4 strategy does not use any indicators. The 4 week high or low price works well to identify markets that are trending . Finding trend is important. 
Make sure last trading day price is highest of 4 weeks or 20 trading day is highest price.

for short 20 day lowest. (upside down) 

After reaching 20 day highest price stock pull back 3 consecutive days when ever day closes higher than previous day (trend starts from here) ( mostly 4th or 5th day) then next day is entry point, then trending resume.

(lowest risk entry point opportunities occur when main trend and minor trend intersects) 

Some traders get confused because they see the market made a 20 day price high a few days earlier; you have to look at the 20 day high in hindsight after it made the 4 consecutive lower closes, otherwise the 20 day high is irrelevant.
