¿How to properly spot S/R?

This is a great example of what I am after. Yesterday support came from a level that I would never pay attention to (my bad). Today I was looking at Previous Day High, that actually provided Resistance during the premarket.

As I was looking at the chart in real time, I was looking for something that actually told me to close my trade and move in the opposite direction around this level but I did not get it. As, although the accelerated demand line was broken after almost reaching R, the trendline was still holding.



Any Ideas are appreciated here.

 

Looks very much like this in the Obvious thread...
Never figured it out...

 

Where did you find that?

Once again with Oil, I have no idea why support showed up at 56.73, did anyone have that level as important today?

 

Look at daily / 4 hour chart man. Stop trading chop. What was once resistance is now support... For now at least

 

Thanks for the input.

Here is daily, but still cant find something that pops up, at least for me.

 

Think and look at what happened there back in end of NOV.
