Why do I keep losing in areas of support and resistance?

Excellent reflection. Especially because it raises a criticism of what basic courses teach us. Fixed lines are a trap for novices.

So does the typical double floor pattern in support no longer work, or does it just need more context?

I cannot agree more with the context. What makes the difference is not the area, but what happens just before and just after reaching it.

If everything is so relative, how do we avoid falling into overthinking? Sometimes so much analysis paralyzes me.

I'm going to read it again with the chart open. I need to apply this to my next ops.

That's how to look at it, not as a simple horizontal line.

And how do you measure validation within the area? Just with price reactions or you also wait for structure break?

One way to filter areas that I use is to see the delta activity and absorption in the DOM. If there is no real interest, I don't get involved.

This should be taught on the first day of any trading course. It is well-structured common sense.

But if we wait for so much confirmation, aren't we late?
