Understanding how to identify and trade these levels is essential for managing risk and finding high-probability trade setups.
Why It Matters
Markets do not move in straight lines. They fluctuate between boundaries established by market participants.
- Identifying these boundaries allows you to buy near the low-risk "floor" (support) and sell near the high-risk "ceiling" (resistance).
- Recognizing when these boundaries break allows you to join new, emerging trends early.
Core Concepts
- Support Zone: A price area where buying interest is strong enough to overcome selling pressure. It is characterized by demand expansion.
- Resistance Zone: A price area where selling interest is strong enough to overcome buying pressure. It is characterized by supply distribution.
- Role Reversal: When support is broken, it turns into resistance. When resistance is broken, it turns into support.
- Psychological Price Levels: Round numbers (e.g., $10, $50, $100) that naturally attract order flow due to cognitive bias.
Identification Rules
- Look for Horizontal Peaks and Valleys: Locate areas where the price has sharply reversed directions multiple times.
- Use Zones, Not Exact Lines: Support and resistance are areas of price congestion, not single-digit numbers. Treat them as bands on your chart.

- Chasing Breakouts on Low Volume: Buying breakouts that lack volume expansion. These frequently turn into "bull traps" or false breakouts.
- Treating Levels as Indestructible: Forgetting that every level will eventually break. Always use stop-loss orders.
