Stock prices don't move in a vacuum. They tend to pause, reverse, or accelerate at predictable price zones — areas where many buyers or sellers previously transacted. Understanding these zones is the foundation of chart-based trading decisions.
In PaperTrade Academy: Look for these levels on the chart panel before placing any simulated trade. Setting stops just below support (for longs) is a core technique covered in the Stop-Losses lesson.
Support is a price level where demand is strong enough to halt a price decline and cause a bounce. Think of it as a floor.
Why support forms:
Price action at support:
$55 → $58 → $52 → $55 (support holds) → $62

Support zone
Resistance is a price level where selling pressure is strong enough to halt a price advance and cause a pullback. Think of it as a ceiling.
Why resistance forms:
Look for price zones where the chart shows:
The best levels are zones, not exact prices. A "support zone" of $48–$50 is more realistic than a precise line at $49.17.

| Decision | How support/resistance helps |
|---|---|
| Entry | Buy near support (long) or near resistance (short) |
| Stop-loss | Place stop just below support (long) or above resistance (short) |
| Target | Use next resistance as the profit target |
| Avoid | Chasing a stock that's already far from support with no clear level |
