2. Entry Rules

Entry criteria are designed to objectively identify when a pre-market gap is likely to resolve with a directional move in the first hour of trading:

Step 1: Gap Identification

• Calculate the Percentage Gap:
  [ \text{Gap %} = \frac{\text{Open Price} - \text{Previous Close}}{\text{Previous Close}} \times 100 ]
• Require a gap ≥ 0.5% for equities or ≥ 5 ticks for futures (e.g., ES contract: 0.25-point ticks; 5 ticks = 1.25 points).
• Confirm gap driven by overnight news (earnings, economic releases, geopolitical events).

Step 2: Pre-Market Price Action Confirmation (5-minute bars)

• Observe pre-market volume spike > 2x average pre-market volume over the previous 5 days in the same time window.
• Confirm directional bias: price holding above (for gap up) or below (for gap down) the pre-market VWAP.

Step 3: Market Open Price Action (1-minute bars)

• Wait for the first 5-minute candle after open.
• Entry trigger criteria depending on gap direction:

• Entry is triggered immediately upon fulfillment of the above price break.

Additional Filters:

• Confirm RSI(14) on 5-minute timeframe is not overbought (>70) for gap ups or oversold (<30) for gap downs to avoid extreme exhaustion.
• ATR(14) on 5-minute bars should be above the 30-day average to ensure sufficient volatility.

3. Exit Rules

Exit strategy manages both winning and losing scenarios to preserve capital and lock in profits efficiently.

Winning Scenario

• Exit when price reaches the profit target (see Section 4).
• Alternatively, trail stop loss using a 5-minute EMA(8): if price closes below EMA(8) on gap-up trades (or above EMA(8) on gap-down trades), exit to preserve gains.
• Maximum trade duration: exit at 10:00 AM EST if neither target nor stop is hit, capturing early session momentum.

Losing Scenario

• Exit immediately when stop loss is hit (see Section 5).
• If price action invalidates the gap bias by closing back inside the previous day's range within 15 minutes, exit to minimize loss.

4. Profit Target Placement

Profit targets are based on measured moves, ATR multiples, and key price levels.

Methods:

• Measured Move: Use the gap size as the initial projection for profit target. For example, if ES opens 2 points above prior close, target a 2-point move further in the gap direction.
• R-Multiples: Aim for a minimum 2R profit target, where R is the initial risk defined by stop loss.
• ATR-Based Target: Use 1.5x to 2x the ATR(5-min) at market open as a profit target.
• Key Levels: Prior day high/low, VWAP, or round numbers that act as natural resistance/support.

Example:

• Gap up of 2 points on ES.
• ATR(5-min) = 1.0 point.
• Profit target = Gap size (2 points) or 2 x R if stop loss is 1 point → target 2 points.

5. Stop Loss Placement

Stop loss placement is important and must balance risk and avoid premature stop-outs.

Methods:

• Structure-Based Stop: Place stop 1-2 ticks beyond the opposite side of the 5-minute candle that triggered entry. For gap-up trades, stop below the 5-minute low; for gap-down trades, stop above the 5-minute high.
• ATR-Based Stop: Use 0.5x to 1.0x ATR(5-min) below entry price.
• Percentage-Based Stop: Maximum 0.25% adverse move from entry price for equities or 10 ticks for futures.

Example:

• Entry on ES at 4200.00 (gap up).
• 5-minute low = 4198.50.
• Place stop at 4198.25 (2 ticks below 5-min low).
• ATR(5-min) = 1.0 point → Stop loss = 0.75 points.

6. Risk Control

Maintaining disciplined risk control is essential to long-term success.

• Max Risk per Trade: 1% of account equity per trade.
• Daily Loss Limit: 3% of account equity; stop trading for the day upon reaching this limit.
• Position Sizing: Calculate position size based on stop loss distance:

[ \text{Position Size} = \frac{\text{Max Risk per Trade}}{\text{Stop Loss in $}} ]

Example:

• Account size: $100,000
• Max risk per trade: $1,000 (1%)
• Stop loss = 2 points on ES × $50/point = $100
• Position size = $1,000 / $100 = 10 contracts

7. Money Management

Different money management techniques can optimize growth and manage drawdowns.

Kelly Criterion

• Estimates optimal bet size based on win rate and reward/risk ratio.
• Formula:

[ f^{} = \frac{bp - q}{b} ]

where:

• (b) = net odds received on the wager (reward/risk ratio - 1)
• (p) = probability of winning
• (q = 1 - p)

Example:

• Win rate (p) = 55%
• R:R = 2:1 → (b = 2 - 1 = 1)
• (f^{*} = \frac{1 * 0.55 - 0.45}{1} = 0.10) (10% of capital)

This is aggressive; in practice, use a fraction (e.g., half Kelly = 5%).

Fixed Fractional

• Risk a fixed percentage of capital per trade (e.g., 1%).
• Easier to implement and control drawdowns.

Scaling In/Out

• Scale in by entering half the position at first signal, full size once setup confirms.
• Scale out by taking partial profits at 1R and trailing stop for remainder.

8. Edge Definition

A clearly defined edge quantifies expected profitability and risk parameters.

• Statistical Advantage: Backtesting pre-market gap trades on ES shows win rates of 55-60% with 2:1 average R:R.
• Win Rate Expectation: 50-60%, depending on news type and instrument.
• R:R Ratio: Target a minimum 2:1 reward-to-risk ratio.
• Volatility Filter: Trades only taken when ATR(5-min) ≥ 30-day average to reduce false signals.

The edge arises from the tendency of informed overnight news to drive continued momentum or structured reversals within the early trading session.

9. Common Mistakes and How to Avoid Them

10. Real-World Example: ES E-mini Futures

Scenario:

• Previous day close: 4200.00
• Overnight news: Strong jobs report released at 8:30 AM EST → ES futures gap up 2.5 points
• Pre-market open price: 4202.50
• ATR(5-min): 1.2 points (above 30-day average of 0.9)
• Pre-market volume: 3x average over past 5 days
• RSI(14) (5-min): 60 (no overbought condition)

Step 1: Gap Identification

[ \text{Gap %} = \frac{4202.50 - 4200.00}{4200.00} \times 100 = 0.06% \quad \text{(0.06% is below 0.5%, but given futures tick size, 2.5 points is significant)} ]

Since ES tick size is 0.25 points, 2.5 points gap = 10 ticks, exceeding the minimum 5 ticks.

Step 2: Pre-market Confirmation

• Volume spike confirmed.
• Price holding above pre-market VWAP.

Step 3: Entry Trigger

• Market open at 9:30 AM EST.
• First 5-minute candle high: 4204.00
• Entry trigger: Buy stop at 4204.25 (1 tick above 5-min high)
• Entry executed at 9:37 AM.

Step 4: Stop Loss

• 5-minute candle low: 4201.50
• Place stop 2 ticks below: 4201.00
• Stop distance = 3.25 points (4204.25 - 4201.00)
• Risk per contract = 3.25 points × $50 = $162.50

Step 5: Position Sizing

• Account size: $100,000
• Max risk = $1,000 (1%)
• Position size = $1,000 / $162.50 ≈ 6 contracts

Step 6: Profit Target

• Measured move: Gap size = 2.5 points
• Target = Entry + 2.5 points = 4206.75
• R = 3.25 points; 2R = 6.5 points → Target at 4204.25 + 6.5 = 4210.75 (more aggressive)
• Use conservative target at 4206.75 initially.

Step 7: Trade Outcome

• Price rallies, hits 4206.75 at 9:50 AM → profit of 2.5 points × 6 contracts × $50 = $750
• Optionally trail stop using EMA(8) on 5-min bars to capture additional upside or exit at target.

Summary

• Risk per contract: $162.50
• Total risk: $975 (6 contracts)
• Profit: $750 (initial target) or more if trailed.

This setup captured the momentum created by the overnight jobs report, respecting volatility and risk parameters.

Conclusion

Assessing overnight news impact on pre-market gaps is a structured, rules-based intraday trading setup that leverages objective criteria such as gap size, volume confirmation, and volatility measures. By adhering to precise entry and exit rules, applying disciplined risk control, and utilizing adaptive money management techniques, experienced traders can exploit the early session price movements with a statistically defined edge. Avoiding common pitfalls and carefully sizing positions further enhances the probability of consistent success in this dynamic environment.
