# New week opening gap (NWOG) > The price range between a market's last close before the weekend and its first open after it — in ICT teaching, Friday's 17:00 close and Sunday's 18:00 open in New York time — kept on the chart with its midpoint for weeks. - Canonical: https://hadalinstruments.com/glossary/new-week-opening-gap/ - Term set: https://hadalinstruments.com/glossary/ --- The market stops for the weekend, and the new week opening gap is the distance between the price it stopped at and the price it came back at. ## The construction Two prices define it. The **close** is the last price before the weekend halt: in ICT teaching, Friday's close at 17:00 New York time, taken from the 16:59 one-minute candle or the 16:00 hourly candle. The **open** is the first price after the reopen, on Sunday at 18:00 New York time. The band between them is the gap. It is **bullish** when Sunday opens above Friday's close and **bearish** when it opens below. Its midpoint is its [consequent encroachment](/glossary/consequent-encroachment/), the name the method also gives the midpoint of a [fair value gap](/glossary/fair-value-gap/). A worked case, with constructed numbers. EUR/USD closes on Friday at 1.0842 and opens on Sunday at 1.0861. The gap runs from 1.0842 to 1.0861, nineteen pips, with its consequent encroachment at 1.08515. A Monday decline that stops at 1.0855 has entered the gap without reaching its midpoint; a later close at 1.0839 has traded through the whole band, and the gap is filled. The bearish mirror, again constructed: GBP/USD closes on Friday at 1.2710 and opens on Sunday at 1.2688. The gap runs from 1.2688 up to 1.2710, twenty-two pips, with its midpoint at 1.2699, and it sits above price until a rally trades back into it. ## Clock, calendar and feed The times live on the New York clock, so they move against UTC and every other timezone when New York changes its clocks, exactly as the [kill zones](/glossary/ict-kill-zones/) do. Holidays move the close: when a market is shut on a Friday, the week's last close comes from the last session that traded. And both prices belong to a feed. A futures contract has one exchange and one set of prints. In spot currencies each broker's last Friday quote and first Sunday quote differ, sometimes by several pips, so the same week prints different gaps on different platforms. A gap quoted without its instrument and feed cannot be found again. ## Size against volatility A nineteen-pip gap is large after a quiet week and small after a weekend of news. Expressing each gap against recent average true range makes gaps from different weeks and different markets comparable, and a minimum size stated the same way keeps the chart from filling with gaps of a pip or two. Both are elections, and a count of gap behaviour quoted without its size rule describes a different population from one that states it. ## Why the teaching keeps it In ICT teaching the weekend gap is a range of prices the market did not trade, and skipped prices are expected to be revisited, to the midpoint or across the whole band. It is the expectation the method attaches to gaps inside continuous trading, applied to a gap made by a halt. Where the gaps sit relative to price also frames the week: an open gap below price is read as a possible destination for a decline, one above as a destination for a rally, and the edges and the midpoint are watched as places a move may stall. The [draw on liquidity](/glossary/draw-on-liquidity/) entry lists unfilled gaps among the targets a bias can point at. ## The last five Teaching keeps several weekly gaps on the chart at once, and the common convention is the most recent five, each with its high, low and midpoint. The number is a setting, not a finding. Some tools also mark the midpoint between two neighbouring weekly gaps as a level of its own, which the teaching calls an event horizon. That is a derived line, and each derived line added to a chart adds another price that a later move can be said to have respected. ## With the daily gaps The weekly gap is the largest of a family. On weekday evenings futures pause for an hour and print a [new day opening gap](/glossary/new-day-opening-gap/) with the same construction, and on United States index products the [opening range gap](/glossary/opening-range-gap/) measures the move from one regular-session close to the next open. A week's daily gaps often sit inside or near its weekly gap, so a chart carrying five weekly gaps and five daily gaps holds up to thirty lines of edges and midpoints. The more lines a chart carries, the likelier any turn lands near one of them, which is the reason a reaction count has to be compared with levels that are not gaps. ## Markets without a weekend Crypto assets trade through the weekend and print no weekend gap on their own spot markets. The bitcoin and ether futures listed in Chicago do close for the weekend, so the same asset can show a weekly gap on a futures chart and none on a spot chart. Equity index futures and spot currencies both halt for the weekend, and the construction applies to them directly. ## Identifying one, step by step 1. **Set the chart to New York time**, on an intraday timeframe, for an instrument that closes over the weekend. 2. **Take the close** of the last candle before the weekend halt: Friday's 16:59 one-minute candle, or the last candle before a holiday closure. 3. **Take the open** of the first candle after the Sunday reopen at 18:00. 4. **Draw the band and its midpoint**, and label the week, because the gap stays on the chart long after the week that printed it. 5. **State the fill rule** before tracking the gap: a wick through the far edge, or a close through it. ## Trading it, as taught Teaching uses the gap in two ways. As a **target**, an open gap in the direction of the bias is a place price is expected to reach, and a position may be held toward its near edge or its midpoint. As a **location**, a return into the gap is watched for a reaction at the near edge or the midpoint, often with a lower-timeframe [market structure shift](/glossary/market-structure-shift/) as the trigger and a stop beyond the far edge. Each is a set of elections: which line is the entry, what counts as a reaction, and what invalidates the gap. A result for one set does not transfer to another. ## Common mistakes Reading the gap from a broker's server clock, which can put the close and the open on the wrong candles. Drawing the gap on one feed and trading it on another. Treating a filled gap as spent in one analysis and as a live level in the next. And counting the gaps price reacted to while forgetting the ones it passed straight through. ## What the gap does not settle The construction is exact: two prices, a band and a midpoint, which two people with the same feed will draw identically. The expectation that price returns to the band, or turns at its midpoint, is a claim about distributions: how often weekly gaps fill, how quickly, and whether their lines hold more often than comparable prices that are not gaps. The weekly gap driver has a row in the [claims ledger](/ict/#ledger), where that verdict renders. The [opening gap indicator](/ict/opening-gap-indicator/) datasheet draws weekly gaps with their midpoints and states, keeping the last five by default. The [two lenses](/glossary/the-two-lenses/) keep the band, which anyone can draw, apart from the claim about what price does there. ## Commonly confused with Neighbouring concepts that get used interchangeably, and the distinction that actually separates them. - **[New day opening gap](https://hadalinstruments.com/glossary/new-day-opening-gap/)** — The same construction on a daily cadence: the gap across the one-hour evening halt futures take on weekdays, usually kept for days rather than weeks. The weekly gap spans the weekend halt that currency and futures markets share. - **[Fair value gap](https://hadalinstruments.com/glossary/fair-value-gap/)** — A fair value gap prints inside continuous trading, where the middle candle crossed the band one-sidedly. An opening gap prints across a halt, where nothing traded at all. Teaching expects price to revisit both; what the empty band records is different. - **[Opening range gap](https://hadalinstruments.com/glossary/opening-range-gap/)** — Measured in regular-session prices on United States index products, from one day's regular close to the next 09:30 open, while the futures keep trading overnight. The weekly gap needs no session convention, because the market is closed. - **A stock's weekend gap** — A stock chart gaps whenever Monday's open differs from Friday's close, and the gap is usually read as a pattern to fade or to follow. The ICT gap is defined on the futures and currency week at fixed New York times, and its edges and midpoint are kept as reference levels for weeks. ## How to measure it in your own data A definition you cannot test is a definition you have to take on trust. This is the shortest honest route from the concept to a number you computed yourself. - **Records you need** — Intraday data for a market that closes over the weekend, with an unambiguous timezone converted to New York time; the instrument's trading calendar, since a holiday moves the week's last close; and the feed, because different feeds print different Friday and Sunday prices. - **What you compute** — For each week, take the last close before the weekend halt and the first open after it; the band between those two prices is the gap, and their mean is its midpoint. Track each gap's states (touched, midpoint reached, filled) under a stated fill rule, keep a stated number of past gaps, and compare any count of reactions with matched levels that are not gaps. - **What the answer tells you** — A visible jump between the week's last candle and the next week's first on an intraday chart, with a band and a midpoint carried to the right. How often price later reacts at those lines, rather than passing through them, is a count to make; the band cannot show it. ## Questions and answers ### What is a new week opening gap (NWOG)? The price range between a market's last close before the weekend and its first open after it. ICT teaching fixes both on the New York clock, Friday's close at 17:00 and Sunday's open at 18:00, and keeps the gap's edges and midpoint as reference levels for the weeks that follow. ### How do you mark an NWOG on a chart? On an intraday chart in New York time, take the close of the last candle before Friday's 17:00 halt and the open of the first candle after Sunday's 18:00 reopen. Draw the band between the two prices and a line at their midpoint. The common convention keeps the last five weekly gaps. ### What is the consequent encroachment of an NWOG? The gap's midpoint, halfway between the Friday close and the Sunday open. Teaching treats it as the gap's most reactive line. That is a claim about behaviour, which a count of reactions at the midpoint against other prices inside the gap would test. ### Do new week opening gaps always get filled? No definition can say always. A gap is filled when price trades back across the whole band. Some weekly gaps fill within hours, some stop at the midpoint and some stay open for weeks; how often each happens, and how quickly, is a distribution to measure market by market. ### Does forex have a new week opening gap? Yes. Spot currencies stop quoting over the weekend, so the last Friday price and the first Sunday price usually differ. The size depends on the feed, because each broker's closing and opening quotes differ, and a gap measured on one platform is not the same object on another. ### What is the difference between an NWOG and an NDOG? Cadence and lifespan. The weekly gap spans the weekend halt and is kept for weeks; the daily gap spans the one-hour evening halt futures take on weekdays and is usually kept for days. The construction, close to open with a midpoint, is the same. ## Where it sits in the ICT sequence The ICT vocabulary in the order the method is taught, with a step for each kind of object. - **Step** — 02 of 08 [Levels](https://hadalinstruments.com/ict/#step-levels): the opens, gaps and ranges a session is measured from - **Also at this step** — [New day opening gap (NDOG)](https://hadalinstruments.com/glossary/new-day-opening-gap/), [Opening range gap (ORG)](https://hadalinstruments.com/glossary/opening-range-gap/), [Central bank dealers range (CBDR)](https://hadalinstruments.com/glossary/central-bank-dealers-range/), [IPDA (interbank price delivery algorithm)](https://hadalinstruments.com/glossary/ipda/) - **Before it** — [ICT weekly profiles](https://hadalinstruments.com/glossary/ict-weekly-profiles/) Time - **After it** — [New day opening gap (NDOG)](https://hadalinstruments.com/glossary/new-day-opening-gap/) Levels - **Every step** — [The ICT vocabulary map, with every term defined](https://hadalinstruments.com/ict/#vocabulary) ## The shape, drawn The smallest arrangement the definition admits.
