[blackcat] L3 Financial Minesweeper: Altman Z ScoreLevel: 3 Background The Altman Z-score is the output of a credit-strength test that gauges a publicly traded manufacturing company's likelihood of bankruptcy. The Altman Z-score is a formula for determining whether a company, notably in the manufacturing space, is headed for bankruptcy. Function The possibility of financial failure or bankruptcy of the enterprise is analyzed and predicted through the comprehensive score. The lower the Z value, the more likely the enterprise will go bankrupt. By calculating the Z value of an enterprise for several consecutive years, we can find out whether the enterprise has signs of financial crisis. Generally speaking, when the Z value is greater than 2.675, it indicates that the financial situation of the enterprise is good, and the possibility of bankruptcy is small; When the value is less than 1.81, it indicates that the enterprise is in a potential bankruptcy crisis; when the Z value is between 1.81 and 2.675, it is called a "gray area, indicating that the financial situation of the enterprise is extremely unstable. Remarks STOCKs ONLY which require financial data. X1~X5 coefficients can be customized for different stock markets. Compared to TradingView official Altman Z-Score Indicator. Feedbacks are appreciated.

normalize_heatmap Description: This was a simple indicator to indicate the heatmap area of an asset price, in a relative given time period. In default the lookback period was set to 50 bars, indicating the current state of the price within the previous lookback period. The color scheme was using the rainbow palette, which set blue as the cooling-off area, and red as the heating area. The indicator doesn't take into account momentum strategy and thus doesn't consider the future direction of the asset price. Note: cooling-off area, can be considered to entry or adding position as a DCA strategy. Data Normalize: norm = (x - min) / (max - min) Feature: Heatmap color condition Weighted Moving average (Additional)

VarianceVariance is a measure of dispersion, simply put, it is measuring how distant data is from it's mean(average). This indicator allows you to see when variance is increasing or decreasing, as well as when it is at an extreme value. Thru this, you can get a more accurate description of risk. When variance is increasing/high, you know to expect larger moves, as data(price) is far and getting farther from the mean. and when it is low/decreasing, you know that price movement is more likely to be less volatile due to data clustering closer to the mean, ie ; smaller values. Variance is not a signal generating indicator in and of itself, but is more a tool to help tell you WHEN to trade. Use in conjunction with signal generating indicators such as Z-score to find entries. For example, trading z score extremes when variance is increasing. Variance works well alongside measurements of historical volatility to get a more accurate measurement of market risk/ volatility .

Volume CompressorTurns volume into a more informative representation, ready to be further analyzed ... Rationale Volume Back in the "before the quant" days I was a big fan of market & volume profile. Thing is J. Steidlmayer had lotta different ideas & works aside of profiling, it's just most of them ain't got to mainstream, one of them was "Hot / Cold volume" (yes, you can't really google it). From my interpretation, the idea was that in a given asset there is a usual constant volume that stays there no matter what, and if it ever changes it changes very slow and gradually; and there's another kind of, so to say, 'active' volume that actually influences price dynamics and very volatile by its nature. So I've met concept lately, and decided to quantify & model it one day when I'll have an idea how. That day was yesterday. Compression When we do music we always use different kinds of filters (low-pass, high pass, etc) for equalization and filtering itself. That stuff we use in finance as well. What we also always use in music are compressors, there dynamic processors that automatically adjust volume so it will be more consistent. Almost all the cool music you hear is compressed (both individual instruments (especially vocals) and the whole track afterwards), otherwise stuff will be too quite and too weak to flex on it, and also DJing it would be a nightmare. I am a big adept of loudness war. So I was like, how can I use compression in finance, when ima get an idea? That day was yesterday as well. Volume structure Being inspired by Steidlmayer's idea, I decided to distinguish volume this way: 1) Passive / static volume. The ~ volume that's always there no matter what (hedges, arbitrages, spread legs, portfolio parts etc etc), doesn't affect things; 2) Active / dynamic volume. The volume that flows from one asset to another, really matters and affects things; 3) Excess volume. The last portion of number 2 volume, that doesn't represent any powerful value to affect things. Now it's clear that we can get rid of number 1 and number 3, the components that don't really matter, and concentrate on number 2 in order to improve information gain, both for ourselves and for the models we feed this data. How? Model I don't wanna explain it all in statistical / DSP way for once. First of all, I think the population of volumes is log-normally distributed, so let's take logs of volumes, now we have a ~ normally distributed data. We take linearly weighted mean, add and subtract linearly weighted standard deviation from it, these would be our thresholds, the borders between different kinds of volumes explained before. The upper threshold is for downward compression, that will not let volume pass it higher. The lower threshold is for upward compression, all the volumes lower than this threshold will be brought up to the threshold's level. Then we apply multipliers to the thresholds in order to adjust em and find the sweet spots. We do it the same way as in sound engineering when we don't aim for overcompression, we adjust the thresholds until they start to touch the signal and all good. Afterwards, we delete all the number 1 and number 3 volume, leaving us exclusively with the clear main component, ready to be processed further. We return the volumes to dem real scale. About the parameters, based on testing I don't recommend changing the thresholds from dem default values, first of all they make sense statistically and second they work as intended. Window length can and should be adjusted, find your own way, or leave the default value. ML (moving location) length is up to you as well. So yeah, you can see now we can smooth the data and make it visually appealing not only by applying a smooth filter over it. All good TV?

Portfolio Laboratory [Kioseff Trading]Hello! This script looks to experiment with historical portfolio performance. However, a hypothetical cash balance is not used; weighted percentage increases and decreases are used. You can select up to 10 assets to include in the portfolio. Long and short positions are possible. Show in the image are the portfolio's weight, the total return of the portfolio and the total return of the asset on the chart over the selected timeframe. Shown in the image above are the constituents of the portfolio, which can include any asset, the weighted percentage gain/loss of the constituents in addition to 10 major indices and their respective total percentage gain/loss over the timeframe. Shown in the image above are the dividend yield % of the portfolio and relevant portfolio metrics - ex-post calculations are applied and are predicated on simple returns. Shown in the image above is a portfolio of all short positions; portfolio calculations adjusted to the modifications. Also shown is a change in the index the portfolio is calculated against. I have been asked a few times to include NIFTY 50 in my scripts - I made sure this was achieved, lol! Show in the image is a performance line of performance of percentage increases/decreases for the index calculated against, the asset on the chart, and the portfolio. All lines start simultaneously on the selected start date at the close price of the session for the asset on your chart. However, the right-hand scale, whether displaying price or percent, cannot be used to assess the performance of each line - they are useful for visualization only and can extend below zero on a low-priced asset. Calculations will not execute correctly when selecting a start date prior to any asset in the portfolio's first trading session; calculations do not begin on the first bar of the asset on your chart. I decided to code the script this way so statistics remain fixed when moving from asset to asset! To compensate for this limitation, I included a label plot and background color change at the first session in which all assets in the portfolio had at least one bar of price data. You can adjust the calculation start date to the date portrayed on the label to test al possible price data! The statistics table, and the performance lines, can be hidden in the user input section. I plan on putting a bit more work into this script. I have some ideas on what to include; however, any input is greatly appreciated! If there's something you would like me to include please let me know. @scheplick mentioned me in a script he recently coded: My inspiration came from his script! I thank him for that!

Z-Score with Buy & Sell SignalsThis is my open-source indicator of z-score with buy and sell indicators. I see there are other z-score indicators, I just am particular about how I like my z-scores calculated and so decided to make my own and add buy and sell signals to help guide me. And I figured I could share it openly here! What is a Z-Score A z-score is a statistical measures of the distance, in standard deviations, a value is from its given mean. It is expressed as a standard deviation (or SD). The further a value (in this case, a stock) is from their mean, the more likely a regression to the mean is possible (i.e. a return to the average). So if a stock is trading at 3 standard deviations away from its mean, then we can anticipate it wanting to regress back towards 1 to 0 standard deviations from its mean (i.e. sell off back to a value that brings it closer to that SD). The inverse is true if it is trading below. Z-Scores and Stocks Stocks, like everything in nature, like to trade between -1 and +1 SD away from its mean. Anything above this, we can interpret that there is "stress" on the stock. Anything over 2.50 is tremendous stress on the stock and we can anticipate that it will want to revert to its mean in the near future and bring that value down to at least 1, ideally between the -0.5 and 0.5 range. Please note, I set the standard VERY high for the indicator to issue a buy and sell signal (/=2.50). Lately with the volatility, stocks have been entering these ranges frequently and so there have been plenty of signals, but traditionally in a stable environment you may not get these signals. I set the bar extremely high because I want to avoid false buy and sell signals (you will still get them though, nothing is perfect!). So the value in this indicator is in interpreting the actual z-score itself, so please be sure you understand exactly what the Z-score is (see the description above). How the indicator works The indicator works by calculating the average Z-Score between a stocks high and low. This indicator will present the average deviation a stock has from its high and low average. The higher the Z-Score, the more "overbought" the stock is. The lower the z-score, the more "oversold" the stock is. It uses the previous 500 candles worth of data to calculate its SMA and its Standard deviation in order to calculate the z-score. Anytime a stock trades 2.50 SDs or more above or below its mean, you will be presented with a Buy or Sell signal, as generally, statistically speaking, after something has travelled 2.50 SDs aware from its mean, there is an increased probability of a reversion happening. You can use this indicator to determine whether the stock is trading within normal parameters or not and to help you in your analysis as to whether or not a stock could be shorted or longed. I personally like this for swing trading on the 1 hour chart; however, this can be used on any time from 1 minute to 1 hour. It also allows you to track a stocks progress in its reversion to the mean. Examples of it in Use: Gold ETF (ARCA: GLD) on 1 minute Dow Jones ETF (ARCA: DIA) on 1 minute (my favourite Stock!) SPY ETF (ARCA: SPY) on 1 hour chart Disclaimer: This is not meant to be placed as a sole and single strategy. It should be used in COJUNCTION with your other strategies to help you make a determination. No indicator is infallible and should never be relied on 100%! Please let me know your questions/comments/experiences/recommendations below! Thanks everyone!

Market Profile Fixed ViewSome instruments does not provide any volume information, therefore, as a fixed volume profile user, I needed a fixed market profile indicator to use the same principles, regardless of whether the volumes are available or not. This script draws a market profile histogram corresponding to price variations within a specific duration, you only need to specify Start and End date/time values to see the histogram on your chart. Details Two lines corresponding to highest/lowest prices are displayed around the histogram The redline corresponds to the POC (point of control) Options Start calculation End calculation Bars number (histogram resolution, currently locked to a max value of 50 bars) Display side/Width (allows to modify size of bars, to the left or to the right) Bars/Borders/POC Color customization Notes This script will probably be updated (to add VAH/VAL zones, and maybe other options). However, some common market profile attributes have not been implemented yet since I don't really use them)
