Overview
Premarket sessions set the levels that matter after the open. Some traders participate directly; many only build the watchlist and wait.
How it works
Track relative volume and news from the early session, mark the premarket high and low, then either trade the level directly with reduced size or use it as the reference after the bell.
Typical setup
- Catalyst with real premarket volume
- Clear premarket high or low
- Reduced size for thin liquidity
Advantages
- First access to a move
- Builds the levels for the regular session
Risks
- Wide spreads and poor fills
- Levels can be invalidated at the open
- Low volume distorts patterns
Common mistakes
- Full size in thin liquidity
- Using market orders on wide spreads
Risk management notes
Treat premarket fills as costlier than regular session fills and size accordingly.
