Nwog Ndog Calculator
Calculate New Week Opening Gap and New Day Opening Gap levels for ICT-based trading. Enter values for instant results with step-by-step formulas.
Formula
Gap Midpoint (CE) = (Gap High + Gap Low) / 2
The gap is defined by the previous close and current open. The midpoint (consequent encroachment) represents the 50% level of the gap. Gap High and Gap Low are the upper and lower bounds. Quarter levels divide the gap into four equal segments for finer analysis.
Worked Examples
Example 1: Bullish Weekly Opening Gap (NWOG)
Problem: EUR/USD closes Friday at 1.0850 and opens Monday at 1.0875. Current price is 1.0860. Calculate the NWOG levels.
Solution: Gap High = 1.0875 (Monday open)\nGap Low = 1.0850 (Friday close)\nGap Size = 1.0875 - 1.0850 = 0.0025 (25 pips)\nMidpoint (CE) = (1.0875 + 1.0850) / 2 = 1.08625\nUpper Quarter = 1.0875 - (0.0025 x 0.25) = 1.086875\nLower Quarter = 1.0850 + (0.0025 x 0.25) = 1.085625\nCurrent price 1.0860 is in the lower half of the gap.
Result: Gap: 1.0850 - 1.0875 (25 pips) | CE: 1.08625 | Direction: Bullish | Price in Lower Half
Example 2: Bearish Daily Opening Gap (NDOG)
Problem: GBP/USD closes at 1.2700 and opens the next session at 1.2680. Current price is 1.2695. Calculate the NDOG levels.
Solution: Gap High = 1.2700 (previous close)\nGap Low = 1.2680 (current open)\nGap Size = 1.2700 - 1.2680 = 0.0020 (20 pips)\nMidpoint (CE) = (1.2700 + 1.2680) / 2 = 1.2690\nCurrent price 1.2695 is in the upper half, above CE.\nBias: bearish gap suggests looking for shorts at upper quarter or gap high.
Result: Gap: 1.2680 - 1.2700 (20 pips) | CE: 1.2690 | Direction: Bearish | Price in Upper Half
Frequently Asked Questions
What is the New Day Opening Gap (NDOG) and how is it different from NWOG?
The New Day Opening Gap (NDOG) is the gap between the previous daily session close and the current daily session open. While the concept is similar to NWOG, NDOG forms on a daily basis and represents shorter-term institutional positioning. In forex, the daily gap often appears at the New York session close (5 PM EST) to the next session open. NDOG levels are typically used for intraday trading decisions, while NWOG levels carry more weight for swing trading and weekly bias. Both gaps use the same calculation methodology, with the midpoint, high, and low serving as key reference levels for trade setups.
Can NWOG and NDOG levels be used together for trade confirmation?
Yes, combining NWOG and NDOG levels provides powerful confluence for trade setups. When an NDOG level aligns closely with an NWOG level, the combined zone becomes a high-probability reaction area. For example, if the weekly gap midpoint sits near the daily gap high, that price level carries double significance for institutional algorithms. Traders can use the weekly gap for directional bias and the daily gap for precise entry timing. A common approach is to identify the weekly bias from NWOG, then wait for an NDOG setup that aligns with that bias during the killzone sessions for optimal trade execution and risk management.
How accurate are NWOG and NDOG levels for predicting price movements?
NWOG and NDOG levels are reference points rather than guaranteed prediction tools. Their accuracy depends on multiple factors including overall market conditions, news events, and alignment with higher timeframe structure. In trending markets, opening gaps in the direction of the trend tend to hold and act as support or resistance more reliably. During ranging or news-driven markets, gaps may be quickly filled and offer less reliable trading signals. Statistical analysis by ICT traders suggests that the gap midpoint is tested approximately 60-70% of the time within the relevant period, but this varies by market pair and volatility conditions.
What are common mistakes traders make when using NWOG and NDOG analysis?
The most common mistake is treating opening gap levels as absolute support and resistance without considering the broader market context and higher timeframe structure. Traders often enter immediately at gap levels without waiting for confirmation through price action patterns like market structure shifts or displacement candles. Another frequent error is using incorrect closing and opening prices, especially across different broker feeds that may have varying session times. Over-reliance on gap levels during high-impact news events is also problematic, as these events can override technical levels entirely. Successful gap traders always combine NWOG and NDOG analysis with killzone timing, liquidity concepts, and proper risk management.
How accurate are the results from Nwog Ndog Calculator?
All calculations use established mathematical formulas and are performed with high-precision arithmetic. Results are accurate to the precision shown. For critical decisions in finance, medicine, or engineering, always verify results with a qualified professional.
How do I get the most accurate result?
Enter values as precisely as possible using the correct units for each field. Check that you have selected the right unit (e.g. kilograms vs pounds, meters vs feet) before calculating. Rounding inputs early can reduce output precision.
