Gap FinderThe Gap Finder Indicator will allow you to quickly identify gaps on the chart. Gaps in this indicator are defined as the "black space" between candles with the space being as small as $0.01. A gap up is one where the previous candle's high is lower than the current candle's low. A gap down is one where the previous candle's low is higher than the current candle's high.
Features:
Highlight Gap Area will show the price levels for the last found gap.
Show Last Only - will show only the last gap to help declutter the chart.
Basic guidelines for Gap trading:
Wait 3-5 Periods to allow the momentum to settle
Take trade on reversal candle with stop above recent high
Exit for profit when the gap fills.
This indicator will work for all timeframes using the definitions above so good for day traders, swing traders and any other style of trader using gaps in their strategy.
Gap
GAP HunterThis indicator shows the GAPs that are formed according to whether the opening price is above or below the rate specified in the selection box. An alarm can be set on these conditions.
NSDT Gap FinderThis script plots gaps between candles.
It uses the "round_to_mintick" feature in the Pinescript code, so it works on any instrument out to 3 decimal places.
If there is a Gap Up (open of current candle is greater than the close of previous candle) it will plot a green arrow under the current candle and plot a label above the current candle to show the Gap Amount.
If there is a Gap Down (open of current candle is less than the close of previous candle) it will plot a red arrow over the current candle and plot a label below the current candle to show the Gap Amount.
You can turn the label and/or the arrow on and off.
I created this indicator to more easily identify gaps in the market. The probability of a gap being filled is extremely high. Some are right away (intraday candle to candle), some take a while (gap from previous day close to current day open), and some make take a long time (close at end of previous week to open at beginning of current week).
This is published free to use and open source code.
Please see my other similar Gap Indicators.
Daily Gap Range
USA Session - Previous Day Close Gap to Current Day Open
Range Gap/Open to Close/Close to CloseThis indicator shows the percentage variation of:
gap
close to close (day including gap)
open to close (without gap)
The green bars represent the days when the variation did not reach the selected range. The red bars show the days when the variation was higher than the selected range.
Best timeframe : DAY
Gap Stats v2This helpful analysis tool displays a table of days a stock has gapped, how much it gapped by and what percentage of the gap was covered.
It is meant to be used on the daily timeframe and can help you distinguish if gaps are going to be filled or not. I like to use it mainly on medium + cap stocks
that have gapped overnight or pre-market and see what the tendency is with how it behaves after a major gap.
SUPERTREND MIXED ICHI-DMI-DONCHIAN-VOL-GAP-HLBox@RLSUPERTREND MIXED ICHI-DMI-VOL-GAP-HLBox@RL
by RegisL76 (lebourg.regis@free.fr)
This script is based on several trend indicators.
* ICHIMOKU (KINKO HYO)
* DMI (Directional Movement Index)
* SUPERTREND ICHIMOKU + SUPERTREND DMI
* DONCHIAN CANAL Optimized with Colored Bars
* HMA Hull
* Fair Value GAP
* VOLUME/ MA Volume
* PRICE / MA Price
* HHLL BOXES
All these indications are visible simultaneously on a single graph. A data table summarizes all the important information to make a good trade decision.
ICHIMOKU Indicator:
The ICHIMOKU indicator is visualized in the traditional way.
ICHIMOKU standard setting values are respected but modifiable. (Traditional defaults = .
An oriented visual symbol, near the last value, indicates the progression (Ascending, Descending or neutral) of the TENKAN-SEN and the KIJUN-SEN as well as the period used.
The CLOUD (KUMO) and the CHIKOU-SPAN are present and are essential for the complete analysis of the ICHIMOKU.
At the top of the graph are visually represented the crossings of the TENKAN and the KIJUN.
Vertical lines, accompanied by labels, make it possible to quickly visualize the particularities of the ICHIMOKU.
A line displays the current bar.
A line visualizes the end of the CLOUD (KUMO) which is shifted 25 bars into the future.
A line visualizes the end of the chikou-span, which is shifted 25 bars in the past.
DIRECTIONAL MOVEMENT INDEX (DMI) : Treated conventionally : DI+, DI-, ADX and associated with a SUPERTREND DMI.
A visual symbol at the bottom of the graph indicates DI+ and DI- crossings
A line of oriented and colored symbols (DMI Line) at the top of the chart indicates the direction and strength of the trend.
SUPERTREND ICHIMOKU + SUPERTREND DMI :
Trend following by SUPERTREND calculation.
DONCHIAN CHANNEL: Treated conventionally. (And optimized by colored bars when overshooting either up or down.
The lines, high and low of the last values of the channel are represented to quickly visualize the level of the RANGE.
SUPERTREND HMA (HULL) Treated conventionally.
The HMA line visually indicates, according to color and direction, the market trend.
A visual symbol at the bottom of the chart indicates opportunities to sell and buy.
VOLUME:
Calculation of the MOBILE AVERAGE of the volume with comparison of the volume compared to the moving average of the volume.
The indications are colored and commented according to the comparison.
PRICE: Calculation of the MOBILE AVERAGE of the price with comparison of the price compared to the moving average of the price.
The indications are colored and commented according to the comparison.
HHLL BOXES:
Visualizes in the form of a box, for a given period, the max high and min low values of the price.
The configuration allows taking into account the high and low wicks of the price or the opening and closing values.
FAIR VALUE GAP :
This indicator displays 'GAP' levels over the current time period and an optional higher time period.
The script takes into account the high/low values of the current bar and compares with the 2 previous bars.
The "gap" is generated from the lack of overlap between these bars. Bearish or bullish gaps are determined by whether the gap is above or below HmaPrice, as they tend to fill, and can be used as targets.
NOTE: FAIR VALUE GAP has no values displayed in the table and/or label.
Important information (DATA) relating to each indicator is displayed in real time in a table and/or a label.
Each information is commented and colored according to direction, value, comparison etc.
Each piece of information indicates the values of the current bar and the previous value (in "FULL" mode).
The other possible modes for viewing the table and/or the label allow a more synthetic view of the information ("CONDENSED" and "MINIMAL" modes).
In order not to overload the vision of the chart too much, the visualization box of the RANGE DONCHIAN, the vertical lines of the shifted marks of the ICHIMOKU, as well as the boxes of the HHLL Boxes indicator are only visualized intermittently (managed by an adjustable time delay ).
The "HISTORICAL INFO READING" configuration parameter set to zero (by default) makes it possible to read all the information of the current bar in progress (Bar #0). All other values allow to read the information of a historical bar. The value 1 reads the information of the bar preceding the current bar (-1). The value 10 makes it possible to read the information of the tenth bar behind (-10) compared to the current bar, etc.
At the bottom of the DATAS table and label, lights, red, green or white indicate quickly summarize the trend from the various indicators.
Each light represents the number of indicators with the same trend at a given time.
Green for a bullish trend, red for a bearish trend and white for a neutral trend.
The conditions for determining a trend are for each indicator:
SUPERTREND ICHIMOHU + DMI: the 2 Super trends together are either bullish or bearish.
Otherwise the signal is neutral.
DMI: 2 main conditions:
BULLISH if DI+ >= DI- and ADX >25.
BEARISH if DI+ < DI- and ADX >25.
NEUTRAL if the 2 conditions are not met.
ICHIMOKU: 3 main conditions:
BULLISH if PRICE above the cloud and TENKAN > KIJUN and GREEN CLOUD AHEAD.
BEARISH if PRICE below the cloud and TENKAN < KIJUN and RED CLOUD AHEAD.
The other additional conditions (Data) complete the analysis and are present for informational purposes of the trend and depend on the context.
DONCHIAN CHANNEL: 1 main condition:
BULLISH: the price has crossed above the HIGH DC line.
BEARISH: the price has gone below the LOW DC line.
NEUTRAL if the price is between the HIGH DC and LOW DC lines
The 2 other complementary conditions (Datas) complete the analysis:
HIGH DC and LOW DC are increasing, falling or stable.
SUPERTREND HMA HULL: The script determines several trend levels:
STRONG BUY, BUY, STRONG SELL, SELL AND NEUTRAL.
VOLUME: 3 trend levels:
VOLUME > MOVING AVERAGE,
VOLUME < MOVING AVERAGE,
VOLUME = MOVING AVERAGE.
PRICE: 3 trend levels:
PRICE > MOVING AVERAGE,
PRICE < MOVING AVERAGE,
PRICE = MOVING AVERAGE.

IX - FAIR VALUE GAP
Cet indicateur affiche les niveaux de 'GAP' sur la période temporelle actuelle ET une période temporelle facultative supérieure.
Le script prend en compte les valeurs haut/bas de la barre actuelle et compare avec les 2 barres précédentes.
Le "gap" est généré à partir du manque de recouvrement entre ces barres.
Les écarts baissiers ou haussiers sont déterminés selon que l'écart est supérieurs ou inférieur à HmaPrice, car ils ont tendance à être comblés, et peuvent être utilisés comme cibles.
NOTA : FAIR VALUE GAP n'a pas de valeurs affichées dans la table et/ou l'étiquette.
Les informations importantes (DATAS) relatives à chaque indicateur sont visualisées en temps réel dans une table et/ou une étiquette.
Chaque information est commentée et colorée en fonction de la direction, de la valeur, de la comparaison etc.
Chaque information indique la valeurs de la barre en cours et la valeur précédente ( en mode "COMPLET").
Les autres modes possibles pour visualiser la table et/ou l'étiquette, permettent une vue plus synthétique des informations (modes "CONDENSÉ" et "MINIMAL").
Afin de ne pas trop surcharger la vision du graphique, la boite de visualisation du RANGE DONCHIAN, les lignes verticales des marques décalées de l'ICHIMOKU, ainsi que les boites de l'indicateur HHLL Boxes ne sont visualisées que de manière intermittente (géré par une temporisation réglable ).
Le paramètre de configuration "HISTORICAL INFO READING" réglé sur zéro (par défaut) permet de lire toutes les informations de la barre actuelle en cours (Barre #0).
Toutes autres valeurs permet de lire les informations d'une barre historique. La valeur 1 permet de lire les informations de la barre précédant la barre en cours (-1).
La valeur 10 permet de lire les information de la dixième barre en arrière (-10) par rapport à la barre en cours, etc.
Dans le bas de la table et de l'étiquette de DATAS, des voyants, rouge, vert ou blanc indique de manière rapide la synthèse de la tendance issue des différents indicateurs.
Chaque voyant représente le nombre d'indicateur ayant la même tendance à un instant donné. Vert pour une tendance Bullish, rouge pour une tendance Bearish et blanc pour une tendance neutre.
Les conditions pour déterminer une tendance sont pour chaque indicateur :
SUPERTREND ICHIMOHU + DMI : les 2 Super trends sont ensemble soit bullish soit Bearish. Sinon le signal est neutre.
DMI : 2 conditions principales :
BULLISH si DI+ >= DI- et ADX >25.
BEARISH si DI+ < DI- et ADX >25.
NEUTRE si les 2 conditions ne sont pas remplies.
ICHIMOKU : 3 conditions principales :

Gapgap indicator
True type:
The gap formed between the closing price of the last bar on Friday of the "current" chart period and the opening price of Monday of the "current" chart period
Fix type :
Displays the "daily" gap between Friday's close and Monday's open in "any" chart period
Intution type :
Any gaps are marked
(Not recommended to use in small cycles. There will be a lot of gaps due to the small transaction volume)
Oxy CandlestickOxymoronic (oxy) candlesticks often appear at significant levels in a chart and can indicate increased probabilities of directional moves.
Typically, green candles are hollow and red candles are filled. An oxymoronic candle is colored bullishly but filled bearishly (solid green) or vice versa (hollow red).
Oxy flags occur when:
1) Price gaps up and closes lower than the open but above the last close. A solid green (or black) candle is bearish.
2) Price gaps down and closes higher than the open but below the last close. A hollow red candle is bullish.
An oxy candle indicates one of three things:
1) Price is going up (bullish oxy)
2) Price is going down (bearish oxy)
3) Price will return to this level (either)
#1 and #2 are the default meaning. If those don't play out then look for #3.
As is the case with most indicators, it is best not to use this indicator in isolation, but to combine it with other forms of analysis to increase your probabilities and to identify significant levels.
Gap calculatorVERSION 1
This indicator base on detection of climax candles (Trend or Trading Range candles also available) then calculate average of open and close of those climax one.
Key-features of Gap line :
1 - forecast pullback
2 - finding support and resistance lines
3 - finding behavior of market
Gap FinderThis indicator finds gaps based on User specified input % threshold in the indicator settings. Histogram plot shows gaps as vertical lines for easy detection. Enjoy!
muh gap! [FAIR VALUE GAP FINDER]Change the colors of the indicator to contrast your chart! Make sure to also change the transparency for the colors.
---
This indicator finds fair value gaps which are inefficiencies in price delivery. Gaps can be used for entry or even bias.
I've included midpoints, lines, and boxes. Boxes have the greatest range with respect to historic PA so keep that in mind.
I will be updating this script in the future, potentially adding an MTF function, mitigation of gaps and alarms.
Let me know if you guys have any additional ideas.

Indicator: Gap Finder [KL]
About gaps:
A gap is a “jump” in a security’s price between the Open and the Prior Close . Gaps are very common in stocks during opening hours, especially when accompanied by catalysts.
What this indicator does:
This script will identify gaps that remained unfilled for at least one candle.
It is very common for gaps to be filled on the first candle, these gaps are arguably less meaningful, so they are ignored by the indicator to reduce the number of lines drawn.
Applications:
Since most gaps eventually get filled, the question is a matter of when . If going with the trend, a trader will open a long/short position when seeing an up/down gap. When going against the trend, then short/long the stock on up/down gaps and consider taking profits when price returns to where the gap originally occurred.
Originally intended for 1D timeframes, but gaps can occur in all timeframes. Applications are limitless.
Gap Absorption StrategyLike the nature, markets don't like the void, and this is something we can take advantage of by trading gaps on some markets.
This technique is well known, so I wanted to write a tiny script based on this strategy to get a bit more comfortable with it.
IMPORTANT: Default parameters wont give you good trades on every markets, you need to modify these parameters to see which proportions correspond to the stock you're trading.
This script triggers signals on predefined variation of a stock price after a gap, and allows its user to configure TP and SL prices corresponding to a specific percentage of this gap movement.
Note: We can observe that opening gaps are often the most interesting.
Options
Trigger: the price variation you want to trigger on (in % of the price)
Stop Loss : in % of the gap
Take profit : in % of the gap
A small table is displayed in the top right corner of the chart to give you TP/SL/Signal prices for each opportunity
SL (red line) and TP (green line) are also displayed on the chart when a signal is triggered
Information concerning the current opportunity is given at the bottom of the chart
Note: This script is based on the Gap-Size-Indicator that I published a few weeks ago.
Void FinderWith the Indicator one can find the voids in price in candles.
Void as in when the close and open of candles are not at the same price
VolatilityLibrary "Volatility"
Functions for determining if volatility (true range) is within or exceeds normal.
The "True Range" (ta.tr) is used for measuring volatility.
Values are normalized by the volume adjusted weighted moving average (VAWMA) to be more like percent moves than price.
current(len) Returns the current price adjusted volatitlity ratio.
Parameters:
len : Number of bars to get a volume adjusted weighted average price.
normal(len, maxDeviation, level, gapDays, spec, res) Returns the normal upper range of volatility. Compensates for overnight gaps within a regular session.
Parameters:
len : Number of bars to measure volatility.
maxDeviation : The limit of volatility before considered an outlier.
level : The amount of standard deviation after cleaning outliers to be considered within normal.
gapDays : The number of days in the past to measure overnight gap volaility.
spec : session.regular (default), session.extended or other time spec.
res : The resolution (default = '1440').
isNormal(len, maxDeviation, level, gapDays, spec, res) Returns true if the volatility (true range) is within normal levels. Compensates for overnight gaps within a regular session.
Parameters:
len : Number of bars to measure volatility.
maxDeviation : The limit of volatility before considered an outlier.
level : The amount of standard deviation after cleaning outliers to be considered within normal.
gapDays : The number of days in the past to measure overnight gap volaility.
spec : session.regular (default), session.extended or other time spec.
res : The resolution (default = '1440').
severity(len, maxDeviation, level, gapDays, spec, res) Returns ratio of the current value to the normal value. Compensates for overnight gaps within a regular session.
Parameters:
len : Number of bars to measure volatility.
maxDeviation : The limit of volatility before considered an outlier.
level : The amount of standard deviation after cleaning outliers to be considered within normal.
gapDays : The number of days in the past to measure overnight gap volaility.
spec : session.regular (default), session.extended or other time spec.
res : The resolution (default = '1440').
GSI (Gap Size Indicator)The purpose of this indicator is to give a quick view of a gap size between two candles, and to detect any gap bigger than the trigger setting.
Options
Mode: Select the display mode (% or Value)
Variation Trigger: Defines the minimum gap size to give a signal, for both positive and negative sides. This option depends on the Mode setting
Show trigger lines: Enable/Disable the display of the Variation Trigger setting lines
Color signals only: When enabled, bars crossing the trigger value are still colored, but other are gray
Show signals only: When enabled, will only show bars corresponding to gaps crossing the trigger value
Notes
Basic alerts on Bullish , Bearish and All gaps are available.
Feel free to suggest any improvement.
Bitcoin - CME Futures Friday Close
This indicator displays the weekly Friday closing price according to the CME trading hours (Friday 4pm CT).
A horizontal line is displayed until the CME opens again on Sunday 5pm CT.
This indicator is based on the thesis, that during the weekend the Bitcoin price tends to mean reverse to the CME closing price of the prior Friday. The level can also act as support/resistance. This indicator gives a visualization of this key level for the relevant time window.
Furthermore the indicator helps to easily identify, if there is an up or down gap in the CME Bitcoin contract.
TC Gaps IndicatorTrade Central Gaps indicator makes it super easy to visualise gaps in your charts in any timeframe. You can also configure the width of gaps in percentage (default is 0.5%).
Customizable Gap FinderThis is a fully customizable gap finder. You can change the color of just about anything, on top of hiding filled/old gaps. This is so you can spot those tiny gaps on something such as futures. Be sure to play around with the settings.
Unfilled Gap DetectorThis indicator displays gaps on a chart within a specified range which have not been filled. It offers the ability to set the minimum gap size to detect as a multiple of the average true range (ATR), as well as the allowed distance from a gap fill for the gap to be considered filled. The use of ATR allows the gap threshold to dynamically change as the stock price and volatility change over time. Lastly, it offers the ability to show gaps which have been filled in addition to unfilled gaps.
The following describes each input's effect on the indicator.
Bars to Search Back: specifies how many bars back in the chart to search for gaps and gap fills (maximum 5000).
ATR Length: specifies the length of the ATR() function used for thresholding
Minimum ATR Multiple For Gap Detection: The minimum gap size as a multiple of the ATR
Minimum ATR Multiple For Gap Fill: The minimum distance between a bar high/low and a gap for it to be considered "filled" as a multiple of ATR
Gaps % Size DistributionThis tool is to visualize the distribution of gap % sizes, i.e. those things that I marked on the main chart. The tool uses the entire history of an instrument.
The detalization depends on the Binning Step parameter. The lower chart timeframe the lower that step should be.
Good luck.
Data Gap PointerUpdating the v3 script made by u/Lemrin + some mods
What this does:
Paints a blue "down arrow" pointer at an intraday bar that has occurred with a skip (e.g. a 1min bar that occurs a few minutes after the previous bar)
Checks for whether the market is open, and only paints arrows if inside open hours (because Extended Hours have lots of bar gaps)
Gap detector
This is a very simple gap indicator derived by comparing the previous opening and next closing price.
Gap down if opening price is lesser than previous closed price.
Gap up if opening is more than previous closed price.
This gap detector use to evaluate the continuation or reversal of next candle and needed to be implement with other indicator such as Moving average or Boilinger band to read the possible direction of trend. Basic knowledge of candlestick pattern may help to predict the direction of next candlestick base on gap up or down of current price.
Alert can be setup using this gap detector accordingly to the time frame of chart.
Multiple time frame is recommended
