Quote from abogdan:
The noise exists on any level. If you trade weekly charts you just simply deal with different kind of frequency and amplitude of the noise compared to, let say, 5 min chart. However, the principles of dealing with this noise will remain relatively the same. There are two major principles of treating the noise on any level:
1. Filter it (using, moving averages, FIR filters, etc.)
2. Use it to trade (employing any counter trend technique like bands, oscillators, RSI etc. that work well on detrended signal)
Those are basics, obviously. But recognizing the noise is a very fruitful exercise for anybody whether you use it or filter it. The question becomes then what signal gives you more $$$ per trade. Simple observation could be also made on that respect:
The sum of all the squiggles is always greater then a straight line connecting the ends
