Support and resistance: what does a level really mean?

Support and resistance are zones where price has turned before — not exact lines, and not promises. Beginners treat them as walls; experienced traders treat them as areas where behaviour changes.

How do you draw them?

• swings, round numbers, moving averages, or something else
• how wide a zone you allow
• what you do when price "breaks" a level and immediately reverses

The support and resistance guide covers the methods.
