How does one look at S/R? Everyone has various ideas/beliefs. A chart would be covered with lines if all the possible scenarios were plotted. I'll list a few, others please add to the list & what is important to you!
1. Previous high/low/open/close; daily, weekly, monthly & yearly.
2. Areas of consolidation by price & or volume; intraday, daily, weekly, monthly, yearly.
3. Floor trader pivots; daily, weekly, monthly.
4. Trendlines; intraday, daily, weekly, monthly.
5. Dynamic pivots or the high/low with the 25%,50%, 75% plotted; again intraday, daily, etc.
6. Moving averages; do I use a 20, 50, 200? What type of moving average: simple, exponential, weighted, volume weighted, Hull, Jurik, etc. Again intraday, daily, etc.
7. Fib retracements/extensions & clusters; intraday, daily ,etc.
8. Bands, channels, pitchfork(Bollinger, Donchian, Keltner, Darvas, Andrews, etc).
From what I've observed over time, sometimes they work/sometimes they don't, a flip of the coin.
