Why session gaps matter for US traders
The NYSE opens at 9:30 AM ET after hours of news and order flow. Gaps of 0.5% to 2% are common. A 1% gap on a $50K account is $500. Without a plan, you lose control. Set rules before the bell.
Rule 1: never trade the first 15 minutes
The first 15 minutes are pure noise. Liquidity is thin, spreads widen, and gaps can reverse. Wait for the market to settle. Let the opening range form. Your edge comes after the chaos.
Rule 2: use gap-fill targets and stop-losses
Gaps often fill within the same session. Set a target at the pre-gap close. Place a stop 1.5x the gap size. For a $1 gap on SPY, stop at $1.50. Stick to the plan.
Rule 3: size down on gap days
Gap days increase volatility. Cut your position size by 50%. If you normally risk $200, risk $100. This protects your capital. Big gaps can trigger stop runs.
