NDOG (New Day Opening Gap): The ICT Concept That Reveals Where Price Wants to Go

What Is the New Day Opening Gap (NDOG)?

Every day in the futures market, something subtle happens that most traders completely ignore—a one-hour gap between when trading stops and when it resumes.

At 5:00 PM EST, the futures market closes. At 6:00 PM EST, it reopens. That 60-minute pause creates a small but significant price gap between the last traded price and the first traded price of the new session.

This is the New Day Opening Gap (NDOG)—one of ICT's most practical concepts for understanding where price wants to go next.

Unlike weekend gaps that are obvious and widely discussed, NDOGs are subtle. They form every single trading day (Monday through Thursday), and they act as magnets for price action. Price consistently revisits these gaps to rebalance the inefficiency created during that hour of zero trading activity.

In this guide, we'll break down exactly how to identify NDOGs, why they matter, and how to use them in your daily trading—whether you're scalping ES, NQ, or any other futures contract.

Why NDOGs Matter: The Liquidity Void Concept

Here's the key insight that makes NDOGs so powerful: no orders are filled during that one-hour market pause.

Think about what that means. Every other price level on your chart has some history of trading activity—buyers and sellers exchanging contracts, building up a record of fair value. But that gap between 5:00 PM and 6:00 PM? Nothing. Zero volume. Zero price discovery.

This creates what ICT calls a liquidity void—an area where the market hasn't established fair value. And markets hate inefficiency. Price will consistently seek to "fill" these gaps, testing the levels where no trading occurred to establish equilibrium.

NDOGs as Fair Value Gaps

If you're already familiar with Fair Value Gaps (FVGs), NDOGs work on the same principle. Both represent areas of price imbalance where the market moved without fully establishing fair value. The difference is that NDOGs are time-based rather than candle-based—they form at the same time every single day, making them predictable and easy to plan around.

This predictability is what makes NDOGs so useful for day traders. You know exactly when they'll form, and you can mark them on your chart before the session even begins.

NDOGs as Support and Resistance

Once price interacts with an NDOG, it doesn't just disappear. These gaps function as dynamic support and resistance zones:

Unfilled NDOGs above price act as draw-on-liquidity targets—price will likely reach up to fill them
Unfilled NDOGs below price act as support zones where buyers may step in
Filled NDOGs can flip from support to resistance (or vice versa) once price trades through them

ICT recommends keeping at least 5 NDOGs marked on your chart at all times (Monday through Friday of the current week) to give you a complete picture of where fair value reference points sit.

How to Identify the New Day Opening Gap: Step-by-Step

Identifying NDOGs is straightforward once you know what you're looking for. Here's the exact process:

Step 1: Mark the 5:00 PM EST Close

On your chart, find the last price printed at 5:00 PM EST (New York local time). This is the closing price of the current session. Draw a horizontal line at this level.

Step 2: Mark the 6:00 PM EST Open

Find the first price printed at 6:00 PM EST. This is the opening price of the new session. Draw a second horizontal line here.

Step 3: Highlight the Gap

The zone between these two lines is your NDOG. Use a rectangle tool or shaded zone to highlight this area on your chart. Color-code it so it's easy to spot—many traders use a semi-transparent blue or gray to distinguish NDOGs from other markings.

Step 4: Find the Consequent Encroachment (C.E.)

The Consequent Encroachment is the 50% level (midpoint) of the NDOG. This is often the most reactive level within the gap—price frequently stalls, reverses, or accelerates at the C.E.

To find it:

Apply a Fibonacci retracement tool from the low to the high of the NDOG
Set your levels to 0, 0.5, and 1
The 0.5 level is your Consequent Encroachment

Step 5: Drop to a Lower Timeframe

Mark your NDOGs on the daily or 1-hour chart, then drop to the 15-minute or 5-minute chart for actual trade execution. The higher timeframe gives you the levels; the lower timeframe gives you the entries.

Quick Tip: NDOG vs. NWOG

Don't confuse NDOG with the New Week Opening Gap (NWOG). The NWOG forms over the weekend—from Friday's 5:00 PM close to Sunday's 6:00 PM open. NWOGs are typically larger and carry more significance as weekly reference points, while NDOGs are your daily fair value markers.

How to Trade the NDOG: Bullish and Bearish Setups

Knowing where NDOGs are is only half the battle. Here's how to actually trade them in both directions.

Bullish NDOG Setup

Scenario 1: Price is above the NDOG

Identify your bullish daily bias (higher timeframe trend, order flow confirmation)
Wait for price to retrace down into the NDOG
Look for a Market Structure Shift (MSS) on the 5-minute or 15-minute chart—a lower low followed by a higher high
Enter long with your stop below the NDOG low
Target the next draw on liquidity above (previous high, unfilled FVG, or higher NDOG)

Scenario 2: Price is below the NDOG

The NDOG becomes your draw on liquidity—price should rally up to fill it
Once price trades through and closes above the NDOG, it flips to support
Look for long entries on retests of the NDOG from above

Bearish NDOG Setup

Scenario 1: Price is below the NDOG

Confirm your bearish daily bias
Wait for price to retrace up into the NDOG
Look for a bearish Market Structure Shift on the lower timeframe
Enter short with your stop above the NDOG high
Target the next draw on liquidity below

Scenario 2: Price is above the NDOG

The NDOG acts as a bearish draw on liquidity—price should drop to fill it
Once price closes below the NDOG, it becomes resistance
Look for short entries on retests of the NDOG from below

The Consequent Encroachment Play

Some of the highest-probability NDOG trades happen right at the C.E. (50% level). Here's why:

Price often wicks into the gap and reverses right at the midpoint
The C.E. represents the "fairest" price within the gap—where institutions are most likely to have resting orders
If price blows through the C.E. with momentum, it's likely heading to fill the entire gap

Use the C.E. as your decision point: hold for continuation if price respects it, or adjust your target if it breaks through cleanly.

NDOG + Other ICT Concepts: Building a Complete Model

NDOGs become significantly more powerful when you layer them with other ICT tools. Here are the highest-value combinations:

NDOG + Kill Zones

The London Kill Zone (2:00–5:00 AM EST) and New York Kill Zone (8:30–11:00 AM EST) are when the most significant price moves happen. If price is approaching an unfilled NDOG during a kill zone, the probability of a reaction increases dramatically.

NDOG + Order Blocks

When an Order Block sits at the same level as an NDOG, you have a confluence zone. These are the highest-probability setups because you have both a time-based inefficiency (the gap) and a price-based institutional footprint (the order block) pointing to the same level.

NDOG + Liquidity Sweeps

Watch for price to sweep liquidity (take out equal highs/lows or previous session highs/lows) before trading into an NDOG. The sweep + NDOG fill combination often produces sharp reversals.

NDOG + IPDA Data Range

ICT teaches that the Interbank Price Delivery Algorithm (IPDA) references the last 20, 40, and 60 trading days of data. NDOGs older than 60 days are generally considered "expired"—the algorithm has moved on. Focus your analysis on NDOGs within the most recent 60-day window.

Common NDOG Mistakes (And How to Avoid Them)

After studying hundreds of NDOG interactions, here are the mistakes that trip up most traders:

Mistake #1: Trading Every NDOG

Not every NDOG deserves a trade. Some form during low-volatility periods and create tiny gaps that aren't worth the spread. Focus on NDOGs that have clear separation between the close and open—at least a few ticks on ES or a couple of points on NQ.

Mistake #2: Ignoring Daily Bias

NDOGs are reference points, not signals. You still need a directional bias from your higher timeframe analysis. Trading against the daily bias just because an NDOG exists is a fast way to blow an account.

Mistake #3: Using the Wrong Times

The times are 5:00 PM and 6:00 PM New York (EST/EDT). Not Chicago time. Not UTC. Not your local time. If your chart platform uses a different timezone, convert accordingly. Getting the times wrong means you're marking the wrong levels.

Mistake #4: Forgetting to Update Your Levels

NDOGs form every day. If you're still trading off Monday's NDOG on Thursday without updating your chart, you're missing fresh levels that may be more relevant. Build a daily pre-session routine that includes marking the most recent NDOG.

Automating NDOG Analysis: Why Manual Charting Isn't Enough

Here's the reality of trading NDOGs manually: it works, but it's tedious. Every single day you need to:

Mark the new NDOG before the session starts
Calculate the Consequent Encroachment
Cross-reference with other ICT levels
Monitor multiple NDOGs for potential fills
Make real-time decisions when price hits your levels

That's a lot of discretionary work—and discretion introduces emotion. Miss one NDOG setup because you were distracted, and you'll spend the rest of the day chasing. Take a trade because you "felt" like the NDOG would hold, and you're gambling.

This is exactly why more ICT traders are moving toward automation. When you codify your NDOG rules into a system, you remove the emotional component entirely.

NDOG Checklist: Your Daily Pre-Session Routine

Use this checklist every day before the New York session opens:

☐ Mark yesterday's NDOG — 5:00 PM close to 6:00 PM open
☐ Calculate the Consequent Encroachment — 50% level of the gap
☐ Check for older unfilled NDOGs — within the last 5 trading days minimum
☐ Identify confluence — Do any NDOGs overlap with order blocks, FVGs, or liquidity levels?
☐ Establish your daily bias — Higher timeframe analysis before you touch a lower timeframe
☐ Set alerts — At the NDOG high, low, and C.E. so you don't have to stare at the chart

This routine takes 5-10 minutes and gives you a clear roadmap for the trading day.

Final Thoughts: NDOGs Are Free Edge

The New Day Opening Gap is one of those ICT concepts that's almost too simple to take seriously. Mark two price levels, highlight the gap, trade the fill. That's it.

But simplicity is the point. NDOGs form at the same time every day, they're based on a real market mechanic (the one-hour trading pause), and they consistently attract price action. You don't need a proprietary indicator or a $500/month data feed. You just need to mark the levels and have the discipline to trade them within the context of your daily bias.

The traders who consistently profit from concepts like NDOG aren't the ones with the most complex setups—they're the ones with consistent execution. Whether you mark these levels manually or let automation handle it, the edge is there for anyone willing to put in the work.
