Quote from NihabaAshi:
Yes...maybe anyone can plot a s/r level but how to trade it is a completely different story.
Couldn't agree more.
However, the issue is that the process of deriving the info is simple to some that may be via a calculator that does it for you or via visually (implies it's being manually derived).
Currently there are about 5 different threads here at ET with traders discussing s/r levels for over the past few trading days...
From what I've seen, nobody was using the same levels and have mentioned at least once in the past about how easy/simpler it is. 
That's really interesting. Had skimmed through two or three of those threads without ever paying much attention to their S/R levels, on the assumption that they'd all have come to the same conclusions. Again, assuming they're using visual levels, I think a lot of the variation would come down to extracting S/R levels from different timeframes?...
In addition, via comparing pivot calculator derived s/r areas and visual s/r areas...
One could debate that s/r work being performed by a pivot calculator or s/r software that plots it all for you instantly...
Is the most simplest form due to all the work being done for us (no thinking).
Wouldn't that classify as being the most simple way. 
I would have thought that most traders would place more faith in visually determined levels/pivot points, simply on the basis that they would know that many other traders would be looking at the exact same charts. However, if all pivot calculators determined the same levels, and a fair proportion of ES traders were using them, then again, they'd have confidence in a consensus agreement. Of course, this all assumes either trend or counter-trend trading. More abstract trading systems could certainly depend on calculated levels.
In contrast, I've seen where others say deriving s/r levels via visually analyzing the data (more thinking in comparison to letting a calculator do it for you) is easier/simpler.
That's my point...it's just a matter of perspective about what's really easy or not and that' directly related to the trader even if its a 10 year old kid.
Yet, I've met profitable traders doing both (pivot calculator or visual).
An analogy...there are traders that ONLY use one monitor for trading.
Yet, others use multiple monitors for trading.
Aren't using multiple monitors too much work (not easy) in comparison to using only one monitor for trading ???
Is it possible that one monitor may be reducing one's trade opportunities by it's own limitations of not having enough screen area ???
Are there traders that have the ability to process more information from multiple monitors in comparison to others using only one monitor ???
A few things to think about. 
Again, interesting point. I agree that simplicity and ease are subjective; the most basic system could seem absolutely overwhelming to a novice, whereas a world class trader/athlete could make the most complex tasks appear effortless.
As for the monitors analogy, that's more a question of style than substance?... I imagine the trader who uses just one monitor finds it easier to narrow his focus, whereas one who relies on multiple monitors finds trading easier when he has more information on which to base his trade decisions. Although both may ultimately achieve the same
ease in trading, I suspect the second trader would face a steeper learning curve, having to absorb and assimilate information from more sources.
Precise levels...hmm.
The fact that many swear that their s/r levels is simple and precise makes me wonder sometimes.
One hundred traders. A 60-min ES chart. Print a hundred copies. One copy, one pencil, one ruler for each trader. Five minutes later, compare the results. How many get paid?...
Let profits speak for precise.
If profitable...they are precise enough.
Lowest common denominator. Absolutely.
