Introduction
The terms New Week Opening Gap (NWOG) and New Day Opening Gap (NDOG) describe price discontinuities between consecutive market sessions. These gaps are prominent in technical analysis frameworks such as ICT (Inner Circle Trader), serving as reference zones for potential support or resistance.
Definition of NWOG
The New Week Opening Gap (NWOG) refers to the difference between the closing price at the end of the week (commonly Friday) and the opening price at the start of the new week (often Sunday evening or Monday open, depending on market). This gap indicates a liquidity void that emerged over the weekend when markets were closed.
Definition of NDOG
The New Day Opening Gap (NDOG) refers to the price difference between the closing price of the previous day and the opening price of the current day. It highlights overnight shifts in sentiment or market influence.
Interpretation in Trading Analysis
Both NWOG and NDOG are interpreted as areas where price may have limited historical transaction activity—thus acting as liquidity zones that price often revisits. They are commonly treated as potential support or resistance levels, as prices tend to “fill” the gap or react around these levels.
Role as Support or Resistance
- If the opening gap is bullish (price opens higher), the gap might act as support.
- If bearish (price opens lower), the gap may act as resistance.
General Formation Mechanisms
- NWOG tends to form over the weekend, influenced by events that occur during market closure, such as geopolitical developments or economic news.
- NDOG occurs between daily sessions and may result from news releases, shifts in supply-demand, or institutional activity outside regular hours.
Trading Approaches Using NWOG and NDOG
Gap Identification
- NWOG: Mark the closing price on Friday and the opening price at the start of the week.
- NDOG: Mark the previous day’s closing price and the new day’s opening price.
Gap Fill Strategy
Many traders anticipate that price will return to fill the gap. This “gap fill” behavior is a core strategy in both daily and weekly contexts.
Breakout and Reversion Strategies
- Breakout: Enter trades in the direction of the gap when price breaks beyond it.
- Reversion: Wait for price to return (“retest”) around the gap zone and enter when reversal signals emerge.
Use of 50% Level
Using the midpoint of the gap—often identified with a Fibonacci tool set at 0%, 50%, 100%—can help locate precise entry levels. The 50% level frequently corresponds to noticeable price reactions.
Tools and Indicators for Visualization
Charting Platforms
Custom indicators are available on platforms like TradingView and others to automatically plot NWOG and NDOG zones. These indicators visually display these gaps on charts.
Enhanced Visualization with Event Horizon PD Array (EHPDA)
Some indicators incorporate the Event Horizon PD Array, a midpoint between adjacent gaps. This provides additional nuance, offering intermediary areas that may influence price behavior.
Timeframe Application
- Weekly Charts: Useful for identifying and contextualizing NWOG zones.
- Daily and Intraday (e.g., 4-hour, 1-hour): Help confirm price movement relative to gap behavior.
- Lower Timeframes: Aid in pinpointing entry and exit with greater precision.
Market Type Variations
NWOG and NDOG behaviors can vary across markets:
- More frequent and rapid gap fills in forex.
- Gaps tied to news in equities.
- Commodities, futures, and indices may show differing gap dynamics depending on global context.
Summary of Key Points
| Aspect | NWOG | NDOG |
|---|---|---|
| Definition | Gap between Friday close and next open | Gap between previous close and current open |
| Formation Window | Weekend | Overnight/daily session |
| Common Behavior | Acts as support/resistance; often filled | Similar behavior; frequent reactions |
| Trading Use | Support/resistance zones; gap-fill/reversion | Same; often used in intraday setups |
| Tools Available | Indicators on charting platforms | Same; often visualized together |
| Enhanced Analysis | EHPDA midpoints (Event Horizon) | EHPDA applicable here as well |
| Timeframes | Weekly → intraday methods | Daily → lower timeframe methods |
| Market Variation | Forex, indices, commodities, stocks—varied gaps | Across multiple markets; behavior differs |
Conclusion
Both NWOG and NDOG offer objective, structural insights into price behavior at session transitions. Their identification and analysis—especially when combined with techniques like gap fills, midpoints, and multi-timeframe confirmation—can support systematic trading decisions. These gaps function as meaningful price zones rather than speculative projections, serving as tools within a broader analytical framework.
