Swing lows and swing highs
A swing low is a session whose low is lower than the sessions on either side of it: a point where a fall stopped and turned. A swing high is the same at the top.
Traders watch the last swing low and swing high because many of them placed orders there before. When the price comes back to those levels, some of those orders are still waiting.
Support and resistance
Support is a price area below the current price where buying has stopped falls before. Resistance is an area above where selling has stopped rises before.
They are areas, not exact prices. A level that breaks often swaps roles: old support that gives way can act as resistance on the way back up.
A higher low, a swing low above the one before it, means the fall stopped earlier than last time. A lower high is the same signal at the top, pointing the other way. Neither is a promise of what comes next.

Practice
- The chart opens on 30 March 2026 with the later sessions hidden.
- Find the lowest point of late February 2026 and note its price.
- Step forward through April. Watch whether the next fall stops above that price, below it, or on it.
