Open Interest Footprint IQ [TradingIQ]Hello Traders! Th e Open Interest Footprint IQ indicator is an advanced visualization tool designed for cryptocurrency markets. It provides a granular, real-time breakdown of open interest changes across different price levels, allowing traders to see how aggressive market participation is distributed within each bar. Unlike standard footprint charts that rely solely on volume, this indicator offers unique insights by focusing on the interaction between price action and changes in open interest (OI) — a leading metric often used to infer trader intent and positioning. How it works The Open Interest Footprint IQ processes lower timeframe price and open interest data to build a footprint-style chart that shows how traders are positioning themselves within each candle. Here’s a breakdown of the process: 1. Granular OI & Price Sampling The script retrieves lower-timeframe data (1-minute, 1-second, or 1-tick, based on your setting). For each candle, it captures: High and low prices Price change direction Change in open interest (OI) 2. Classifying Trader Behavior For each lower-timeframe segment, the indicator determines the type of positioning occurring based on price movement and OI change: If price is moving up and open interest is increasing, it suggests that long positions are being opened. This is considered a "Longs Opening" event, labeled as UU (Up/Up). If price is moving up but open interest is decreasing, it indicates that short positions are being closed. This is referred to as UD (Up/Down), or "Shorts Closing." If price is moving down and open interest is increasing, it signals that short positions are being opened. This is known as DU (Down/Up), or "Shorts Opening." If price is moving down while open interest is also decreasing, it means that long positions are being closed. This is labeled as DD (Down/Down), or "Longs Closing." These are stored in separate arrays and displayed at specific price levels. It is particularly useful for identifying: Where longs or shorts are opening/closing positions Stacked imbalances (indicative of potential absorption or exhaustion) Value area zones and POC (Point of Control) based on OI, not volume This footprint runs on your choice of sub-bar granularity and is ideal for high-frequency trading, scalping, and entries based on order flow dynamics. Key Features Footprint Visualization At each price level within a candle: Long/short opening and closing behavior is broken down. Delta (net open interest change) is displayed both numerically and color-coded. Optional gradient coloring shows intensity and type of flow (longs/shorts opened/closed). Cumulative or per-bar reset modes allow you to track OI evolution over time. The image above explains the information that each Footprint box shows across a candlestick! Each footprint box shows: OI Delta OI Delta % Longs Opened (LO) Longs Closed (LC) Shorts Opened (SO) Shorts Closed (SC) The image above explains the color-coding feature of the indicator. Boxes are color coded to show which position action dominated at the price area. For this example: Green boxes = Long positions being opened dominated Purple boxes = Long positions being closed dominated Red boxes = Short positions being opened dominated Yellow boxes = Short positions being closed dominated All colors are customizable. Additionally, for traders who are only interested in whether OI increased/decreased, a "two-color" option is available in the settings. For the two-color option, footprint boxes can be one of two colors. Showing whether OI increased or decreased at the level. Cumulative Levels Open Interest Footprint IQ contains a "Cumulative Levels" feature that tracks/stores open interest change at tick levels over time, rather than resetting per bar. With the "Cumulative Levels" feature enabled, traders can see open interest changes persist across all candlesticks. This feature is useful for determining whether longs opening, longs closing, shorts opening, or shorts closing are dominating at particular price areas over time rather than on a single bar. A useful feature to see if shorts/longs are favoring certain price throughout the day, week, month, etc. Input Settings Explained Granularity (Dropdown: Granularity) Options: 1-Minute, 1-Second, 1-Tick Determines how finely the script samples the lower timeframe data to construct the footprint. For precision: 1-Tick = Highest accuracy, but more resource-intensive. 1-Second/1-Minute = Suitable for broader or more zoomed-out analysis. Tick Level Distance (Tick Level Distance (0 = Auto)) Defines the vertical spacing between levels in the footprint chart. If 0, the script uses an automatic calculation based on ATR to adapt to volatility. Set a manual value (e.g., 5) to control the height granularity of each level in ticks. Cumulative Levels (Toggle) If enabled, the footprint builds cumulatively over time, rather than resetting per candle. Use case: Visualize ongoing buildup of OI activity across a session or day. Cumulative Levels Reset TF (Timeframe) Sets the reset interval for the cumulative view (e.g., reset daily, hourly, etc.) Works only when Cumulative Levels is enabled. Delta Box Display Settings Show Delta Percentage Toggles the display of the percentage change in OI across the footprint level. Helpful to gauge how aggressive positioning is relative to total OI at that level. Show Longs/Shorts (Opened/Closed) Show Longs Opened: Displays OI increase in up candles (price ↑, OI ↑). Show Longs Closed: Displays OI decrease in down candles (price ↓, OI ↓). Show Shorts Opened: OI increase in down candles (price ↓, OI ↑). Show Shorts Closed: OI decrease in up candles (price ↑, OI ↓). These behaviors are color-coded to give traders instant context: Blue-green for longs opening. Purple for longs closing. Red for shorts opening. Yellow for shorts closing. Value Area & POC Value Area % (Value Area %) Controls how much cumulative open interest is used to define the value area. Example: 70% means the smallest range of prices that contains 70% of total OI in that bar will be marked. Helps identify zones of interest, support/resistance, and institutional levels. The image above explains how to identify the VAH/VAL/POC shown by Open Interest Footprint IQ. VAH = Upper 🞂 POC = ● VAL = Lower 🞂 Imbalances Imbalance Percentage Defines the minimum delta % required at a level to be marked as an imbalance. If the net open interest change at a level exceeds this threshold, a visual marker appears. Stacked Imbalance Count If the number of consecutive imbalance levels meets this count, a “Stacked Imbalance” alert will trigger. This can signal aggressive buying or selling pressure, potential breakout zones, or institutional absorption. Color Settings Longs Opened / Closed, Shorts Opened / Closed Customize the color palette for each order flow behavior. These colors appear in the background gradient of the footprint boxes. Up/Down Only Mode Toggle to override all behavior-based colors with a single Up Color and Down Color. Useful if you prefer a simple bull/bear view. Up Color / Down Color If "Up/Down Only" is enabled, these two colors are used to represent all net positive or negative deltas. Special Notes Crypto only: This script works only with crypto tickers on TradingView. For other assets (stocks, futures), a warning message will appear instead. OI data must be available from the exchange (many perpetual pairs support this). If the footprint is too small or invisible, increase your tick level spacing in the settings. Alerts When a stacked imbalance is detected, an alert is fired ("Stacked Imbalance"). This feature is useful for automated systems, bots, or simply staying informed of potential trade setups. And that's all for now! If you have any questions or features you'd like to see feel free to share them in the comments below! Thank you traders!

Footprint IQ Pro [TradingIQ]Hello Traders! Introducing "Footprint IQ Pro"! Footprint IQ Pro is an all-in-one Footprint indicator with several unique features. Features Calculated delta at tick level Calculated delta ratio at tick level Calculated buy volume at tick level Calculated sell volume at tick level Imbalance detection Stacked imbalance detection Stacked imbalance alerts Value area and POC detection Highest +net delta levels detection Lowest -net delta levels detection CVD by tick levels Customizable values area percentage The image above thoroughly outlines what each metric in the delta boxes shows! Metrics In Delta Boxes "δ:", " δ%:", " ⧎: ", " ◭: ", " ⧩: " δ Delta (Difference between buy and sell volume) δ% Delta Ratio (Delta as a percentage of total volume) ⧎ Total Volume At Level (Total volume at the price area) ◭ Total Buy Volume At Level (Total buy volume at the price area) ⧩ Total Sell Volume At Level (total sell volume at the price area) Each metric comes with a corresponding symbol. That said, until you become comfortable with the symbol, you can also turn on the descriptive labels setting! The image above exemplifies the feature. The image above shows Footprint IQ's full power! Additionally, traders with an upgraded TradingView plan can make use of the "1-Second" feature Footprint IQ offers! The image above shows each footprint generated using 1-second volume data. 1-second data is highly granular compared to 1-minute data and, consequently, each footprint is exceptionally more accurate! Imbalance Detection Footprint IQ pro is capable of detecting user-defined delta imbalances. The image above further explains how Footprint IQ detects imbalances! The imbalance percentage is customizable in the settings, and is set to 70% by default. Therefore, When net delta is positive, and the positive net delta constitutes >=70% of the total volume, a buying imbalance will be detected (upwards triangle). When net delta is negative, and the negative net delta constitutes >=70% of the total volume, a buying imbalance will be detected (downwards triangle). Stacked Imbalance Detection In addition to imbalance detection, Footprint IQ Pro can also detect stacked imbalances! The image above shows Footprint IQ Pro detecting stacked imbalances! Stacked imbalances occur when consecutive imbalances at sequential price areas occur. Stacked imbalances are generally interpreted as significant price moves that are supported by volume, rather than a significant result with disproportionate effort. The criteria for stacked imbalance detection (how many imbalances must occur at sequential price areas) is customizable in the settings. The default value is three. Therefore, when three imbalances occur at sequential price areas, golden triangles will begin to print to show a stacked imbalance. Additionally, traders can set alerts for when stacked imbalances occur! Highest +Delta and Highest -Delta Levels In addition to being a fully-fledged Footprint indicator, Footprint IQ Pro goes one step further by detecting price areas where the greater +Delta and -Delta are! The image above shows price behavior near highest +Delta price areas detected by Footprint IQ! These +Delta levels are considered important as there has been strong interest from buyers at these price areas when they are traded at. It's expected that these levels can function as support points that are supported by volume. The image above shows a similar function for resistance points! Blue lines = High +Delta Detected Price Areas Red lines = High -Delta Detected Price Areas Value Area Detection Similar to traditional volume profile, Footprint IQ Pro displays the value area per bar. Green lines next to each footprint show the value area for the bar. The value area % is customizable in the settings. CVD Levels Footprint IQ Pro is capable of storing historical volume delta information to provide CVD measurements at each price area! The image above exemplifies this feature! When this feature is enabled, you will see the CVD of each price area, rather than the net delta! And that's it! Thank you so much to TradingView for offering the greatest charting platform for everyone to create on! If you have any feature requests you'd like to see for Footprint IQ, please feel free to share them with us! Thank you!

Volume Delta Candles HTF [TradingFinder] LTF Volume Candles 🔵 Introduction In financial markets, understanding the concepts of supply and demand and their impact on price movements is of paramount importance. Supply and demand, as fundamental pillars of economics, reflect the interaction between buyers and sellers. When buyers' strength surpasses that of sellers, demand increases, and prices tend to rise. Conversely, when sellers dominate buyers, supply overtakes demand, causing prices to drop. These interactions play a crucial role in determining market trends, price reversal points, and trading decisions. Volume Delta Candles offer traders a practical way to visualize trading activity within each candlestick. By integrating data from lower timeframes or live market feeds, these candles eliminate the need for standalone volume indicators. They present the proportions of buying and selling volume as intuitive colored bars, making it easier to interpret market dynamics at a glance. Additionally, they encapsulate critical metrics like peak delta, lowest delta, and net delta, allowing traders to grasp the market's internal order flow with greater precision. In financial markets, grasping the interplay between supply and demand and its influence on price movements is crucial for successful trading. These fundamental economic forces reflect the ongoing balance between buyers and sellers in the market. When buyers exert greater strength than sellers, demand dominates, driving prices upward. Conversely, when sellers take control, supply surpasses demand, and prices decline. Understanding these dynamics is essential for identifying market trends, pinpointing reversal points, and making informed trading decisions. Volume Delta Candles provide an innovative method for evaluating trading activity within individual candlesticks, offering a simplified view without relying on separate volume indicators. By leveraging lower timeframe or real-time data, this tool visualizes the distribution of buying and selling volumes within a candle through color-coded bars. This visual representation enables traders to quickly assess market sentiment and understand the forces driving price action. Buyer and seller strength is a critical concept that focuses on the ratio of buying to selling volumes. This ratio not only provides insights into the market's current state but also serves as a leading indicator for detecting potential shifts in trends. Traders often rely on volume analysis to identify significant supply and demand zones, guiding their entry and exit strategies. Delta Candles translate these complex metrics, such as Maximum Delta, Minimum Delta, and Final Delta, into an easy-to-read visual format using Japanese candlestick structures, making them an invaluable resource for analyzing order flows and market momentum. By merging the principles of supply and demand with comprehensive volume analysis, tools like the indicator introduced here offer unparalleled clarity into market behavior. This indicator calculates the relative strength of supply and demand for each candlestick by analyzing the ratio of buyers to sellers. 🔵 How to Use The presented indicator is a powerful tool for analyzing supply and demand strength in financial markets. It helps traders identify the strengths and weaknesses of buyers and sellers and utilize this information for better decision-making. 🟣 Analyzing the Highest Volume Trades on Candles A unique feature of this indicator is the visualization of price levels with the highest trade volume for each candlestick. These levels are marked as black lines on the candles, indicating prices where most trades occurred. This information is invaluable for identifying key supply and demand zones, which often act as support or resistance levels. 🟣 Trend Confirmation The indicator enables traders to confirm bullish or bearish trends by observing changes in buyer and seller strength. When buyer strength increases and demand surpasses supply, the likelihood of a bullish trend continuation grows. Conversely, decreasing buyer strength and increasing seller strength may signal a potential bearish trend reversal. 🟣 Adjusting Timeframes and Calculation Methods Users can customize the indicator's candlestick timeframe to align with their trading strategy. Additionally, they can switch between moving average and current candle modes to achieve more precise market analysis. This indicator, with its accurate and visual data display, is a practical and reliable tool for market analysts and traders. Using it can help traders make better decisions and identify optimal entry and exit points. 🔵 Settings Lower Time Frame Volume : This setting determines which timeframe the indicator should use to identify the price levels with the highest trade volume. These levels, displayed as black lines on the candlesticks, indicate prices where the most trades occurred. It is recommended that users align this timeframe with their primary chart’s timeframe. As a general rule : If the main chart’s timeframe is low (e.g., 1-minute or 5-minute), it is better to keep this setting at a similarly low timeframe. As the main chart’s timeframe increases (e.g., daily or weekly), it is advisable to set this parameter to a higher timeframe for more aligned data analysis. Cumulative Mode : Current Candle : Strength is calculated only for the current candlestick. EMA (Exponential Moving Average) : The strength is calculated using an exponential moving average, suitable for identifying longer-term trends. Calculation Period : The default period for the exponential moving average (EMA) is set to 21. Users can modify this value for more precise analysis based on their specific requirements. Ultra Data : This option enables users to view more detailed data from various market sources, such as Forex, Crypto, or Stocks. When activated, the indicator aggregates and displays volume data from multiple sources. 🟣 Table Settings Show Info Table : This option determines whether the information table is displayed on the chart. When enabled, the table appears in a corner of the chart and provides details about the strength of buyers and sellers. Table Size : Users can adjust the size of the text within the table to improve readability. Table Position : This setting defines the table’s placement on the chart. 🔵 Conclusion The indicator introduced in this article is designed as an advanced tool for analyzing supply and demand dynamics in financial markets.

Volume / Open Interest "Footprint" - By Leviathan This script generates a footprint-style bar (profile) based on the aggregated volume or open interest data within your chart's visible range. You can choose from three different heatmap visualizations: Volume Delta/OI Delta, Total Volume/Total OI, and Buy vs. Sell Volume/OI Increase vs. Decrease. How to use the indicator: 1. Add it to your chart. 2. The script will use your chart's visible range and generate a footprint bar on the right side of the screen. You can move left/right, zoom in/zoom out, and the bar's data will be updated automatically. Settings: - Source: This input lets you choose the data that will be displayed in the footprint bar. - Resolution: Resolution is the number of rows displayed in a bar. Increasing it will provide more granular data, and vice versa. You might need to decrease the resolution when viewing larger ranges. - Type: Choose between 3 types of visualization: Total (Total Volume or Total Open Interest increase), UP/DOWN (Buy Volume vs Sell Volume or OI Increase vs OI Decrease), and Delta (Buy Volume - Sell Volume or OI Increase - OI Decrease). - Positive Delta Levels: This function will draw boxes (levels) where Delta is positive. These levels can serve as significant points of interest, S/R, targets, etc., because they mark the zones where there was an increase in buy pressure/position opening. - Volume Aggregation: You can aggregate volume data from 8 different sources. Make sure to check if volume data is reported in base or quote currency and turn on the RQC (Reported in Quote Currency) function accordingly. - Other settings mostly include appearance inputs. Read the tooltips for more info.

RS: Footprint This is live only Footprint indicator. Warning: TV does not provide tick by tick data and updates come in snapshots . Based on this, this indicator can never show precisely what is happening on the bid/ask. What it shows is only an approximation that works well enough if the tape is not too fast. Use it at your own risk, with the warning above in mind! Footprint can be used in two modes: Delta - with bid/ask delta numbers on the left, at the same price level and the total volume numbers on the right Bid vs Ask - with the bid on the left and the ask on the right; the coloring is based on the diagonal difference Zoom in to fit the candles; optionally hide default candles.

Real Cummulative Delta (New TV Function)Thanks to the new TradingView indicator Up/Down Volume, it is now possible to get accurate information on Agression (market buying vs market selling) However, as they only provide the value of delta, I've made this indicator to show the cummulative value, in the form of candles. It is great to detect divergences in the macro and in the micro scale (As in divergences in each candle and divergences in higher or lower tops or bottoms) Hope you can make good use of it!

Realtime Footprint The purpose of this script is to gain a better understanding of the order flow by the footprint. To that end, i have added unusual features in addition to the standard features. I use "Real Time 5D Profile by LucF" main engine to create basic footprint(profile type) and added some popular features and my favorites. This script can only be used in realtime, because tradingview doesn't provide historical Bid/Ask date. Bid/Ask date used this script are up/down ticks. This script can only be used by time based chart (1m, 5m , 60m and daily etc) This script use many labels and these are limited max 500, so you can't display many bars. If you want to display foot print bars longer, turn off the unused sub-display function. Default setting is footprint is 25 labels, IB count is 1, COT high and Ratio high is 1, COT low and Ratio low is 1 and Delta Box Ratio Volume is 1 , total 29. plus UA , IB stripes , ladder fading mark use several labels. ///////// General Setting /////////// Resets on Volume / Range bar : If you want to use simple time based Resets on, please set Total Volume is 0. Your timeframe is always the first condition. So if you set Total Volume is 1000, both conditions(Volume >= 1000 and your timeframe start next bar) must be met. (that is, new footprint bar doesn't start at when total volume = exactly 1000). Ticks per row and Maximum row of Bar : 1 is minimum size(tick). "Maximum row of Bar" decide the number of rows used in one footprint. 1 row is created from 1 label, so you need to reduce this number to display many footprints (Max label is 500). Volume Filter and For Calculation and Display : "Volume Filter" decide minimum size of using volume for this script. "For Calculation and Display" is used to convert volume to an integer. This script only use integer to make profile look better (I contained Bid number and Ask number in one row( one label) to saving labels. This require to make no difference in width by the number of digits and this script corresponds integers from 0 to 3 digits). ex) Symbol average volume size is from 0.0001 to 0.001. You decide only use Volume >= 0.0005 by "Volume Filter". Next, you convert volume to integer, by setting "For Calculation and Display" is 1000 (0.0005 * 1000 = 5). If 0.00052 → 5.2 → 5, 0.00058 → 5.8 → 6 (Decimal numbers are rounded off) This integer is used to all calculation in this script. //////// Main Display /////// Footprint, Total, Row Delta, Diagonal Delta and Profile : "Footprint" display Ask and Bid per row. "Total" display Ask + Bid per row. "Row Delta" display Ask - Bid per row. "Diagonal Delta" display Ask(row N) - Bid(row N -1) per row. Profile display Total Volume(Ask + Bid) per row by using Block. Profile Block coloring are decided by Row Delta value(default: positive Row Delta (Ask > Bid) is greenish colors and negative Row Delta (Ask < Bid) is reddish colors.) Volume per Profile Block, Row Imbalance Ratio and Delta Bull/Bear/Neutral Colors : "Volume per Profile Block" decide one block contain how many total volume. ex) When you set 20, Total volume 70 display 3 block. The maximum number of blocks that can be used per low is 20. So if you set 20, Total volume 400 is 20 blocks. total volume 800 is 20 blocks too. "Row Imbalance Ratio" decide block coloring. The row imbalance is that the difference between Ask and Bid (row delta) is large. default is x3, x2 and x1. The larger the difference, the brighter the color. ex) Ask 30 Bid 10 is light green. Ask 20 Bid 10 is green. Ask 11 Bid 10 is dark green. Ask 0 Bid 1 is light red. Ask 1 Bid 2 is red. ask 30 Bid 59 is dark green. Ask 10 Bid 10 is neutral color(gray) profile coloring is reflected same row's other elements(Ask, Bid, Total and Delta) too. It's because one label can only use one text color. /////// Sub Display /////// Delta, total and Commitment of Traders : "Delta" is total Ask - total Bid in one footprint bar. Total is total Ask + total Bid in one footprint bar. "Commitment of traders" is variation of "Delta". COT High is reset to 0 when current highest is touched. COT Low is opposite. Basic concept of Delta is to compare price with Delta. Ordinary, when price move up, delta is positive. Price move down is negative delta. This is because market orders move price and market orders are counted by Delta (although this description is not exactly correct). But, sometimes prices do not move even though many market orders are putting pressure on price , or conversely, price move strongly without many market orders. This is key point. Big player absorb market orders by iceberg order(Subdivide large orders and pretend to be small limit orders. Small limit orders look weak in the order book, but they are added each time you fill, so they are more powerful than they look.), so price don't move. On the other hand, when the price is moving easily, smart players may be aiming to attract and counterattack to a better price for them. It's more of a sport than science, and there's always no right response. Pay attention to the relationship between price, volume and delta. ex) If COT Low is large negative value, it means many sell market orders is coming, but iceberg order is absorbing their attack at limit order. you should not do buy entry, only this clue. but this is one of the hints. "Delta, Box Ratio and Total texts is contained same label and its color are "Delta" coloring. Positive Delta is Delta Bull color(green),Negative Delta is Delta Bear Color and Delta = 0 is Neutral Color(gray). When Delta direction and price direction are opposite is Delta Divergence Color(yellow). I didn't add the cumulative volume delta because I prefer to display the CVD line on the price chart rather than the number. Box Ratio , Box Ratio Divisor and Heavy Box Ratio Ratio : This is not ordinary footprint features, but I like this concept so I added. Box Ratio by Richard W. Arms is simple but useful tool. calculation is "total volume (one bar) divided by Bar range (highest - lowest)." When Bull and bear are fighting fiercely this number become large, and then important price move happen. I made average BR from something like 5 SMA and if current BR exceeds average BR x (Heavy Box Ratio Ratio), BR box mark will be filled. Box Ratio Divisor is used to good looking display(BR multiplied by Box Ratio Divisor is rounded off and displayed as an integer) Diagonal Imbalance Count , D IB Mark and D IB Stripes : Diagonal Imbalance is defined by "Diagonal Imbalance Ratio". ex) You set 2. When Ask(row N) 30 Bid(row N -1)10, it's 30 > 10*2, so positive Diagonal Imbalance. When Ask(row N) 4 Bid(row N -1)9, it's 4*2 < 9, so negative Diagonal Imbalance. This calculation does not use equals to avoid Ask(row N) 0 Bid(row N -1)0 became Diagonal Imbalance. Ask(row N) 0 Bid(row N -1)0, it's 0 = 0*2, not Diagonal Imbalance. Ask(row N) 10 Bid(row N -1)5, it's 10 = 5*2, not Diagonal Imbalance. "D IB Mark" emphasize Ask or Bid number which is dominant side(Winner of Diagonal Imbalance calculation), by under line. "Diagonal Imbalance Count" compare Ask side D IB Mark to Bid side D IB Mark in one footprint. Coloring depend on which is more aggressive side (it has many IB Mark) and When Aggressive direction and price direction are opposite is Delta Divergence Color(yellow). "D IB Stripes" is a function that further emphasizes with an arrow Mark, when a DIB mark is added on the same side for three consecutive row. Three consecutive arrow is added at third row. Unfinished Auction, Ratio Bounds and Ladder fading Mark : "Unfinished Auction" emphasize highest or lowest row which has both Ask and Bid, by Delta Divergence Color(yellow) XXXXXX mark. Unfinished Auction sometimes has magnet effect, price may touch and breakout at UA side in the future. This concept is famous as profit taking target than entry decision. But, I'm interested in the case that Big player make fake breakout at UA side and trapped retail traders, and then do reversal with retail traders stop-loss hunt. Anyway, it's not stand alone signal. "Ratio Bounds" gauge decrease of pressure at extreme price. Ratio Bounds High is number which second highest ask is divided by highest ask. Ratio Bounds Low is number which second lowest bid is divided by lowest bid. The larger the number, the less momentum the price has. ex)first footprint bar has Ratio Bounds Low 2, second footprint bar has RBL 4, third footprint bar has RBL 20. This indicates that the bear's power is gradually diminishing. "Ladder fading mark" emphasizes the decrease of the value in 3 consecutive row at extreme price. I added two type Marks. Ask/Bid type(triangle Mark) is Ask/Bid values are decreasing of three consecutive row at extreme price. Row Imbalance type(Diamond Mark) are row Imbalance values are decreasing of three consecutive row at extreme price. ex)Third lowest Bid 40, second lowest Bid 10 and lowest Bid 5 have triangle up Mark. That is bear's power is gradually diminishing. (This Mark only check Bid value at lowest price and Ask value at highest price). Third highest row delta + 60, second highest row delta + 5, highest delta - 20 have diamond Mark. That is Bull's power is gradually diminishing. Sub display use Delta colors at bottom of Sub display section. ////// Candle & POC ///////// candle and POC : Ordinary, "POC" Point of Control is row of largest total volume, but this script'POC is volume weighted average. This is because the regular POC was visually displayed by the profile ,and I was influenced LucF's ideas. POC coloring is decided in relation to the previous POC. When current POC is higher than previous POC, color is UP Bar Color(green). In the opposite case, Down Bar color is used. POC Divergence Color is used when Current POC is up but current bar close is lower than open (Down price Bar),or in the opposite case. POC coloring has option also highlight background by Delta Divergence Color(yellow). but bg color is displayed at your time frame current price bar not current footprint bar. The basic explanation is over. I add some image to promote understanding basic ideas.
