For me it comes down to how will the market respond to the tool? There are so many indicators and lines to put on a chart. I think that more people use pivots and respond to them. Remember that there are daily, weekly and monthly pivots. I put the weekly on my 60 minute charts and daily on my 5 minutes. They carry weight like trend lines.
I use the VWAP for isolating a conditional trade that has a high predictability. It is like pattern recognition and specific parameters for execution.
My charts can lean to the complex side, because I am very familiar with my tools and I prefer the confirmation of as many tools that enhance the outcome, and filter fakeouts. Why settle for two, when with careful work and paintbars, you can have confirmation, visuals for stops, cycle forecast lines, and alerts to make trading more precise, and for me simpler. It is a checklist.
Some people don't care for complexity. For me the basic simple chart is like binary computer code of zero or one. The advanced chart like a programming language. Finally there is a highly functional chart, like windows operating system. The complexity is hidden behind paintbars and alerts. The design work is refined and for each market condition, the tools are available. When you have a question of validity of a trade, there are confirmations and preset qualifiers. Also with alerts, you are not watching the screen over trading.
So to keep with the subject, use them both, and develop tools to determine market conditions that they work best in.
I attached a chart that is an example of what I mean by paint bar simplicity. It is running about 30 tuned indicators that are hidden, but trigger when the paintbars show. So simply when I get a vertical concentration of paintbars it means to me, the trend is weakening, get ready for a pullback or some choppier trading. The paintbars are color coded for early warnings in oscillating markets, and some to find the momentum tops of longer trends. Quotetracker makes this process reasonable to set up.
