[blackcat] L1 Close Histogram OscillatorLevel: 1 Background A histogram is a special chart that is applied to statistical data that is divided into numerically ordered groups. For example groups with close relationships in the vicinity like "Close-ref(Close ,1)", "Close-ref(Close,2)" and so on. A histogram provides a snapshot of all the data so that you can quickly get an overview of the historical data, especially its general shape.In a histogram, the bars are linked - in contrast to a bar chart for categorical data, in which the bars represent categories that are in no particular order and are separated. The height of each bar in a histogram indicates either the number of individuals (called the frequency) in each group or the percentage of individuals (the relative frequency) in each group. Each individual in the data set falls into exactly one bar. Function L2 Close Histogram Oscillator is a novel overbought and oversold indicator that estimate the trend state by counting a specific bar relationship nearby. Once nearby bars reach consensus, it may spread to global quickly. The reason why I got this inspiration is because I have been engaged in the research of blockchain consensus mechanism. The market is a complex system, and its consensus depends on the common human characteristics: greed and fear. The trend of the market often also conforms to sociological characteristics. Maybe it's a bit complicated for me to say that. However, if you understand the principle of the spread of rumors and viruses, you can understand the situation where some individuals in the market have local consensus and gradually spread to the overall situation. This is the process of trend formation. Key Signal fastcounter --> fast close histogram counters slowcounter --> slow close histogram counters attention --> bottom price appears, with height of 10 in white readybuy --> a small position buy opportunity after first bottom detected, with height of 20 in yellow buylow --> a small position buy at low price, with height of 30 in lime longentry --> a confirmed long entry signal by close histogram counter, with height of 40 in green risk --> oscillator top is reached and trend reversal may happen, with height drop from 100 to 80 in red Pros and Cons Pros: 1. since this is based on consensus formation principle, i think this is a leading indicator by spreading local consensus to global 2. it is an oscillator, overbought and oversold can be easily observed. Cons: 1. the model is not complex enough to depict market behavior exactly. 2. sideways and chop market will make this indicator's output hard to read. Remarks This is rare! I combined my previous theory of developing cellular automata with the market to produce such a weird indicator. I hope to inspire everyone and study market behavior in a deeper level. Readme In real life, I am a prolific inventor. I have successfully applied for more than 60 international and regional patents in the past 12 years. But in the past two years or so, I have tried to transfer my creativity to the development of trading strategies. Tradingview is the ideal platform for me. I am selecting and contributing some of the hundreds of scripts to publish in Tradingview community. Welcome everyone to interact with me to discuss these interesting pine scripts. The scripts posted are categorized into 5 levels according to my efforts or manhours put into these works. Level 1 : interesting script snippets or distinctive improvement from classic indicators or strategy. Level 1 scripts can usually appear in more complex indicators as a function module or element. Level 2 : composite indicator/strategy. By selecting or combining several independent or dependent functions or sub indicators in proper way, the composite script exhibits a resonance phenomenon which can filter out noise or fake trading signal to enhance trading confidence level. Level 3 : comprehensive indicator/strategy. They are simple trading systems based on my strategies. They are commonly containing several or all of entry signal, close signal, stop loss, take profit, re-entry, risk management, and position sizing techniques. Even some interesting fundamental and mass psychological aspects are incorporated. Level 4 : script snippets or functions that do not disclose source code. Interesting element that can reveal market laws and work as raw material for indicators and strategies. If you find Level 1~2 scripts are helpful, Level 4 is a private version that took me far more efforts to develop. Level 5 : indicator/strategy that do not disclose source code. private version of Level 3 script with my accumulated script processing skills or a large number of custom functions. I had a private function library built in past two years. Level 5 scripts use many of them to achieve private trading strategy.

3-Bar and 4-Bar PlaysThis indicator helps identify 3-bar and 4-bar plays, which are price action patterns consisting of a wide ranging bar that breaks above or below resistance or support, followed by one or two collecting/consolidating bars, then a continuation bar in the direction of the new trend. The 3 and 4-bar play is taught by Jared Wesley and Anmol Singh at Live Traders. The indicator works by looking for a wide ranging bar breaking out of an offset donchian channel, followed by one or two consolidating bars, then a continuation in the direction of the move. The script will place a label on the chart when it spots the pattern and alerts can be set up. Enjoy!

Bar Balance [LucF]Bar Balance extracts the number of up, down and neutral intrabars contained in each chart bar, revealing information on the strength of price movement. It can display stacked columns representing raw up/down/neutral intrabar counts, or an up/down balance line which can be calculated and visualized in many different ways. WARNING: This is an analysis tool that works on historical bars only. It does not show any realtime information, and thus cannot be used to issue alerts or for automated trading. When realtime bars elapse, the indicator will require a browser refresh, a change to its Inputs or to the chart's timeframe/symbol to recalculate and display information on those elapsed bars. Once a trader understands this, the indicator can be used advantageously to make discretionary trading decisions. Traders used to work with my  Delta Volume Columns Pro  will feel right at home in this indicator's Inputs . It has lots of options, allowing it to be used in many different ways. If you value the bar balance information this indicator mines, I hope you will find the time required to master the use of Bar Balance well worth the investment. █  OVERVIEW The indicator has two modes: Columns and Line . Columns • In Columns mode you can display stacked Up/Down/Neutral columns. • The "Up" section represents the count of intrabars where `close > open`, "Down" where `close < open` and "Neutral" where `close = open`. • The Up section always appears above the centerline, the Down section below. The Neutral section overlaps the centerline, split halfway above and below it.  The Up and Down sections start where the Neutral section ends, when there is one. • The Up and Down sections can be colored independently using 7 different methods. • The signal line plotted in Line mode can also be displayed in Columns mode. Line • Displays a single balance line using a zero centerline. • A variable number of independent methods can be used to calculate the line (6), determine its color (5), and color the fill (5).  You can thus evaluate the state of 3 different components with this single line. • A "Divergence Levels" feature will use the line to automatically draw expanding levels on divergence events. Features available in both modes • The color of all components can be selected from 15 base colors, with 16 gradient levels used for each base color in the indicator's gradients. • A zero line can show a 6-state aggregate value of the three main volume balance modes. • The background can be colored using any of 5 different methods. • Chart bars can be colored using 5 different methods. • Divergence and large neutral count ratio events can be shown in either Columns or Line mode, calculated in one of 4 different methods. • Markers on 6 different conditions can be displayed. █  CONCEPTS Intrabar inspection Intrabar inspection means the indicator looks at lower timeframe bars ( intrabars ) making up a given chart bar to gather its information. If your chart is on a 1-hour timeframe and the intrabar resolution determined by the indicator is 5 minutes, then 12 intrabars will be analyzed for each chart bar and the count of up/down/neutral intrabars among those will be tallied. Bar Balances and calculation methods The indicator uses a variety of methods to evaluate bar balance and to derive other calculations from them: 1. Balance on Bar : Uses the relative importance of instant Up and Down counts on the bar. 2. Balance Averages : Uses the difference between the EMAs of Up and Down counts. 3. Balance Momentum : Starts by calculating, separately for both Up and Down counts, the difference between the same EMAs used in Balance Averages and an SMA of double the period used for the EMAs. These differences are then aggregated and finally, a bounded momentum of that aggregate is calculated using RSI. 4. Markers Bias : It sums the bull/bear occurrences of the four previous markers over a user-defined period (the default is 14). 5. Combined Balances : This is the aggregate of the instant bull/bear bias of the three main bar balances. 6. Dual Up/Down Averages : This is a display mode showing the EMA calculated for each of the Up and Down counts. Interpretation of neutral intrabars What do neutral intrabars mean? When price does not change during a bar, it can be because there is simply no interest in the market, or because of a perfect balance between buyers and sellers. The latter being more improbable, Bar Balance assumes that neutral bars reveal a lack of interest, which entails uncertainty. That is the reason why the option is provided to interpret ratios of neutral intrabars greater than 50% as divergences. It is also the rationale behind the option to dampen signal lines on the inverse ratio of neutral intrabars, so that zero intrabars do not affect the signal, and progressively larger proportions of neutral intrabars will reduce the signal's amplitude, as the balance calcs using the up/down counts lose significance. The impact of the dampening will vary with markets. Weaker markets such as cryptos will often contain greater numbers of neutral intrabars, so dampening the Line in that sector will have a greater impact than in more liquid markets. █  FEATURES 1 — Columns • While the size of the Up/Down columns always represents their respective importance on the bar, their coloring mode is independent. The default setup uses a standard coloring mode where the Up/Down columns over/under the zero line are always in the bull/bear color with a higher intensity for the winning side. Six other coloring modes allow you to pack more information in the columns. When choosing to color the top columns using a bull/bear gradient on Balance Averages, for example, you will end up with bull/bear colored tops. In order for the color of the bottom columns to continue to show the instant bar balance, you can then choose the "Up/Down Ratio on Bar — Dual Solid Colors" coloring mode to make those bars the color of the winning side for that bar. • Line mode shows only the line, but Columns mode allows displaying the line along with it. If the scale of the line is different than that of the scale of the columns, the line will often appear flat. Traders may find even a flat line useful as its bull/bear colors will be easily distinguishable. 2 — Line • The default setup for Line mode uses a calculation on "Balance Momentum", with a fill on the longer-term "Balance Averages" and a line color based on the "Markers Bias". With the background set on "Line vs Divergence Levels" and the zero line on the hard-coded "Combined Bar Balances", you have access to five distinct sources of information at a glance, to which you can add divergences, divergences levels and chart bar coloring. This provides powerful potential in displaying bar balance information. • When no columns are displayed, Line mode can show the full scale of whichever line you choose to calculate because the columns' scale no longer interferes with the line's scale. • Note that when "Balance on Bar" is selected, the Neutral count is also displayed as a ratio of the balance line. This is the only instance where the Neutral count is displayed in Line mode. • The "Dual Up/Down Averages" is an exception as it displays two lines: one average for the Up counts and another for the Down counts. This mode will be most useful when Columns are also displayed, as it provides a reference for the top and bottom columns. 3 — Zero Line The zero line can be colored using two methods, both based on the Combined Balances, i.e., the aggregate of the instant bull/bear bias of the three main bar balances. • In "Six-state Dual Color Gradient" mode, a dot appears on every bar. Its color reflects the bull/bear state of the Combined Balances, and the dot's brightness reflects the tally of balance biases. • In "Dual Solid Colors (All Bull/All Bear Only)" a dot only appears when all three balances are either bullish or bearish. The resulting pattern is identical to that of Marker 1. 4 — Divergences • Divergences are displayed as a small circle at the top of the scale. Four different types of divergence events can be detected. Divergences occur whenever the bull/bear bias of the method used diverges with the bar's price direction. • An option allows you to include in divergence events instances where the count of neutral intrabars exceeds 50% of the total intrabar count. • The divergence levels are dynamic levels that automatically build from the line's values on divergence events. On consecutive divergences, the levels will expand, creating a channel. This implementation of the divergence levels corresponds to my view that divergences indicate anomalies, hesitations, points of uncertainty if you will. It excludes any association of a pre-determined bullish/bearish bias to divergences. Accordingly, the levels merely take note of divergence events and mark those points in time with levels. Traders then have a reference point from which they can evaluate further movement. The bull/bear/neutral colors used to plot the levels are also congruent with this view in that they are determined by price's position relative to the levels, which is how I think divergences can be put to the most effective use. 5 — Background • The background can show a bull/bear gradient on four different calculations. You can adjust its brightness to make its visual importance proportional to how you use it in your analysis. 6 — Chart bars • Chart bars can be colored using five different methods. • You have the option of emptying the body of bars where volume does not increase, as does my TLD indicator, the idea behind this being that movement on bars where volume does not increase is less relevant. 7 — Intrabar Resolution You can choose between three modes. Two of them are automatic and one is manual:   a) Fast, Longer history, Auto-Steps (~12 intrabars) : Optimized for speed and deeper history. Uses an average minimum of 12 intrabars.   b) More Precise, Shorter History Auto-Steps (~24 intrabars) : Uses finer intrabar resolution. It is slower and provides less history. Uses an average minimum of 24 intrabars.   c) Fixed : Uses the fixed resolution of your choice. Auto-Steps calculations vary for 24/7 and conventional markets in order to achieve the proper target of minimum intrabars. You can choose to view the intrabar resolution currently used to calculate delta volume. It is the default. The proper selection of the intrabar resolution is important. It must achieve maximal granularity to produce precise results while not unduly slowing down calculations, or worse, causing runtime errors. 8 — Markers Six markers are available: 1. Combined Balances Agreement : All three Bar Balances are either bullish or bearish. 2. Up or Down % Agrees With Bar : An up marker will appear when the percentage of up intrabars in an up chart bar is greater than the specified percentage. Conditions mirror to down bars. 3. Divergence confirmations By Price : One of the four types of balance calculations can be used to detect divergences with price. Confirmations occur when the bar following the divergence confirms the balance bias. Note that the divergence events used here do not include neutral intrabar events. 4. Balance Transitions : Bull/bear transitions of the selected balance. 5. Markers Bias Transitions : Bull/bear transitions of the Markers Bias. 6. Divergence Confirmations By Line : Marks points where the line first breaches a divergence level. Markers appear when the condition is detected, without delay. Since nothing is plotted in realtime, markers do not appear on the realtime bar. 9 — Settings • Two modes can be selected to dampen the line on the ratio of neutral intrabars. • A distinct weight can be attributed to the count of the latter half of intrabars, on the assumption that later intrabars may be more important in determining the outcome of chart bars. • Allows control over the periods of the different moving averages used in calculations. • The default periods used for the various calculations define the following hierarchy from slow to fast:   Balance Averages: 50,   Balance Momentum: 20,   Dual Up/Down Averages: 20,   Marker Bias: 10. █  LIMITATIONS • This script uses a special characteristic of the `security()` function allowing the inspection of intrabars—which is not officially supported by TradingView. • The method used does not work on the realtime bar—only on historical bars. • The indicator only works on some chart resolutions: 3, 5, 10, 15 and 30 minutes, 1, 2, 4, 6, and 12 hours, 1 day, 1 week and 1 month. The script’s code can be modified to run on other resolutions, but chart resolutions must be divisible by the lower resolution used for intrabars and the stepping mechanism could require adaptation. • When using the "Line vs Divergence Levels — Dual Color Gradient" color mode to fill the line, background or chart bars, keep in mind that a line calculation mode must be defined for it to work, as it determines gradients on the movement of the line relative to divergence levels. If the line is hidden, it will not work. • When the difference between the chart’s resolution and the intrabar resolution is too great, runtime errors will occur. The Auto-Steps selection mechanisms should avoid this. • Alerts do not work reliably when `security()` is used at intrabar resolutions. Accordingly, no alerts are configured in the indicator. • The color model used in the indicator provides for fancy visuals that come at a price; when you change values in Inputs , it can take 20 seconds for the changes to materialize. Luckily, once your color setup is complete, the color model does not have a large performance impact, as in normal operation the `security()` calls will become the most important factor in determining response time. Also, once in a while a runtime error will occur when you change inputs. Just making another change will usually bring the indicator back up. █  RAMBLINGS Is this thing useful? I'll let you decide. Bar Balance acts somewhat like an X-Ray on bars. The intrabars it analyzes are no secret; one can simply change the chart's resolution to see the same intrabars the indicator uses. What the indicator brings to traders is the precise count of up/down/neutral intrabars and, more importantly, the calculations it derives from them to present the information in a way that can make it easier to use in trading decisions. How reliable is Bar Balance information? By the same token that an up bar does not guarantee that more up bars will follow, future price movements cannot be inferred from the mere count of up/down/neutral intrabars. Price movement during any chart bar for which, let's say, 12 intrabars are analyzed, could be due to only one of those intrabars. One can thus easily see how only relying on bar balance information could be very misleading. The rationale behind Bar Balance is that when the information mined for multiple chart bars is aggregated, it can provide insight into the history behind chart bars, and thus some bias as to the strength of movements. An up chart bar where 11/12 intrabars are also up is assumed to be stronger than the same up bar where only 2/12 intrabars are up. This logic is not bulletproof, and sometimes Bar Balance will stray. Also, keep in mind that balance lines do not represent price momentum as RSI would. Bar Balance calculations have no idea where price is. Their perspective, like that of any historian, is very limited, constrained that it is to the narrow universe of up/down/neutral intrabar counts. You will thus see instances where price is moving up while Balance Momentum, for example, is moving down. When Bar Balance performs as intended, this indicates that the rally is weakening, which does necessarily imply that price will reverse. Occasionally, price will merrily continue to advance on weakening strength. Divergences Most of the divergence detection methods used here rely on a difference between the bias of a calculation involving a multi-bar average and a given bar's price direction. When using "Bar Balance on Bar" however, only the bar's balance and price movement are used. This is the default mode. As usual, divergences are points of interest because they reveal imbalances, which may or may not become turning points. I do not share the overwhelming enthusiasm traders have for the purported ability of bullish/bearish divergences to indicate imminent reversals. Superfluity In "The Bed of Procrustes", Nassim Nicholas Taleb writes: To bankrupt a fool, give him information . Bar Balance can display lots of information. While learning to use a new indicator inevitably requires an adaptation period where we put it through its paces and try out all its options, once you have become used to Bar Balance and decide to adopt it, rigorously eliminate the components you don't use and configure the remaining ones so their visual prominence reflects their relative importance in your analysis. I tried to provide flexible options for traders to control this indicator's visuals for that exact reason—not for window dressing. █  NOTES For traders • To avoid misleading traders who don't read script descriptions, the indicator shows nothing in the realtime bar. • The Data Window shows key values for the indicator. • All gradients used in this indicator determine their brightness intensities using advances/declines in the signal—not their relative position in a fixed scale. • Note that because of the way gradients are optimized internally, changing their brightness will sometimes require bringing down the value a few steps before you see an impact. • Because this indicator does not use volume, it will work on all markets. For coders • For those interested in gradients, this script uses an advanced version of the Advance/Decline gradient function from the PineCoders Color Gradient (16 colors) Framework . It allows more precise control over the range, steps and min/max values of the gradients. • I use the PineCoders Coding Conventions for Pine to write my scripts. • I used functions modified from the PineCoders MTF Selection Framework for the selection of timeframes. █  THANKS TO: — alexgrover who helped me think through the dampening method used to attenuate signal lines on high ratios of neutral intrabars. — A guy called Kuan who commented on a Backtest Rookies presentation of their Volume Profile indicator . The technique I use to inspect intrabars is derived from Kuan's code. — theheirophant , my partner in the exploration of the sometimes weird abysses of `security()`’s behavior at intrabar resolutions. — midtownsk8rguy , my brilliant companion in mining the depths of Pine graphics.

Backward Number of BarsThis indicator was written in order to apply bar limit in strategies and it was published as open code so that everyone can use it. When backtesting with stock market api data, we determine how many bars should be, not from which date the data will be drawn. For example, we can draw 1000 bar data from stock exchange and perform the backtest on this data. You can plan your strategy by checking the number of bars you test with the window () == 1 parameter here while checking through Tradingview to check that the test we performed gives correct results.

[LunaOwl] RSI 美國線 (RSI Bar, RSIB)Last year, I saw someone using the candle innovation called "RSI Candle" or "RSIC". so let me have the idea of making RSIB. the Candlestick was Steve Nison in the 1990s. He introduced the concept from Japan to America and published it in the book "Candlestick Course". Welles Wilder is the creator of the relative strength index. after several years of commodity trading, Wilder focused on technical analysis. In 1978 he published "New Concepts in the Technology Trading System". RSI is the new momentum oscillator mentioned in the book. then, if you use Bars to display RSI, it might be an artistic idea. everyone is familiar with the method of use. 以前看過人家使用 " RSI 蠟燭線 "（RSIC）的版本，於是就想做一下美國線的版本。1990年代史蒂夫．尼森將蠟燭線的概念從日本引進華爾街，並在《陰線陽線》詳細介紹；威爾德是 RSI 的作者，做商品交易的他專注於研究技術分析，1978年他出版《技術交易系統新概念》提到了這個。如果用美國線表示 RSI 會是另一個模樣。至於它的用法大家都很熟悉了。 The purpose of publishing Chinese Scripts is to make Pine close to more Chinese user. 發布中文腳本的目的，是希望可以讓 Pine 親近更多中文圈的使用者。

vline() Function for Pine Script v4.0+It's been a long time coming, but here is a versatile vline() function applicable to PSv4.0+ utilizing line.new(). I decided to finally figure this out at the request of another member recently. I have been waiting myself for months, but it's now time for an idea who's time has come to unleash upon planet Pine Script. It's a handy little function I believe will be very useful in the future. It only requires 4 parameters of BarIndex, Color, LineStyle, and LineWidth. Make sure you place it in an appropriate if() block to use it properly. As displayed above, this plots every 10 bars using a conditional statement employing the rarely used modulus operator. Use it as you please, this is free code to implement into your new Pine projects. I don't require an credit for any one to use this function. I simply don't want any credit. I would however like to see some great ideas utilizing this when I randomly and accidentally come across them in the public library. I didn't know where to put this script, so I just tossed into the "Trend Analysis" category. I'm pondering we members need a "Miscellaneous" category some time in the future. The comments section below is solely just for commenting and other remarks, ideas, compliments, etc... regarding only this indicator, not others. If you do have any questions or comments regarding this indicator, I will consider your inquiries, thoughts, and concepts presented below in the comments section, when time provides it. When my indicators achieve more prevalent use by TV members, I will implement more ideas when they present themselves as worthy additions. As always, "Like" it if you simply just like it with a proper thumbs up, and also return to my scripts list occasionally for additional postings. Have a profitable future everyone!

Volume & Dollar BarsThis scriptlet is a part of an ongoing project and attempts at volume and dollar bar identification. The original idea is taken from excellent books 'Hands-On Machine Learning for Algorithmic Trading' (2019) by Stefan Jansen and 'Advances in Financial Machine Learning' (2018) by Marcos Lopez de Prado. Statement of Purpose I am an advocate of Open source and against those who publish their code with a lock icon. My code and ideas are aimed at people with critical thinking, who are able to take an informative and responsible decision when it comes to investing their funds. I do not guarantee that all of my ideas will perform well. As usual, they require a certain degree of your sound judgment. My final aim is to provide you with coding techniques that you could use in your own scripts and strategies.

Intra-bar VolumeDisclamer : READ THIS BEFORE USING IT !!! I have take and try to improuve the source code of indicator "intra-bar volume" by backtest-rookies.com This indicator categorized the volume in lower timeframe, if the candle close up it's a buying volume, if it close down... Beware that is not easy to work with different TF on tradingview so you have some limitation on the TF with this indicator. Also in TV we can't have a mutable variable in a security fonction.. so my approche is not clean but it works, if someone find better way, please comment or contact me :) So by default the indicator can work on the following TF : 5m 15m 30m 60m 120m 240m 480m 720m 1D 1W 12M. But ... this indicator need a lower timeframe and the number of bar to work correctly, in my code i suppose that the market run 24/7, so you need to adapte it or use intraday TF for other market. To make sure that the indicator work correctly i have juste add circle, if it's green the buying+selling+balance volume is equal to the volume on the last close candle. If it's red theire is a problem. I hope you enjoy it, feel free to modify the code and comment if you have any sugestion, i have just make it so maybe i will ajust some part of the code.

Three-Bar Inside Bar PaternAuthor: Johnan Prathap TASC March 2011 The typical inside bar two-bar view indicates minimal activity in a market. It is defined as a bar (or series of bars) that is completely within the range of the preceding bar; that is, it has a higher low and lower high than the bar immediately before it. Some traders consider a bar an inside bar if the high and low are equal to the previous bar or where there are several consecutive bars within the range of a previous bar. Many analysts tend to view inside bars as an indication of declining market activity, or possibly a prelude to a large movement in either direction.
