Zscore

Z Score Enhanced Time Segmented Volume (Multi MA)**THIS VERSION HAS BEEN STANDARDIZED WITH A Z SCORE CALCULATION AND ALLOWS THE USER TO SELECT WHICH MOVING AVERAGE THEY WOULD LIKE TO UTILIZE FOR THE SIGNAL LINE** Chart shows the Non-Standardized Enhanced Time Segmented Volume (Multi MA) with default settings on top and the Standardized version with default settings on the bottom. Time Segmented Volume was developed by Worden Brothers, Inc to be a leading indicator by comparing various time segments of both price and volume . Essentialy it is designed to measure the amount of money flowing in and out of an instrument. Time Segmented Volume was originally ported to TradingView by user @liw0 and later corrected by user @vitelot. I never quite understood how to read Time Segmented Volume until I ran across a version by user @storma where they indicated when price would be long or short, but that code also utilized the incorrect calculation from user @liw0. In an effort to make Time Segmented Volume more accessible and easier to read, I have re-coded it here. The calculations are based on the code from @vitelot and I have added direction indicators below the chart. If the histogram (TSV) is greater than zero and greater than the moving average, price should be moving long and there will be a green box below the chart. If TSV falls below the moving average while still being greater than zero, the trend may be exhausting and has been coded to read Price Action Long - FAILURE with a black x below the chart. If the histogram (TSV) is less than zero and less than the moving average, price should be moving short and there will be a red box below the chart. If TSV rises above the moving average while still being less than zero, the trend may be exhausting and has been coded to read Price Action Short - FAILURE with a black x below the chart. At times, the moving average may be above zero while TSV is below zero or vice versa. In these situations the chart will indicate long or short based on whether or not TSV is greater or less than zero. It is possible a new trend may be forming as the moving average obviously lags, but also possible price is consolidating with little volume and causing TSV to oscillate close to zero. **Z Score // Standardized Option ** Thist Standardized code implements all of the above but also allows the user to select a threshold level that should not need to be adjusted for each instrument (since the output is standardized). If the TSV value meets the long and short signal requirements above and TSV is greater than the threshold values a green or red box will print ABOVE the oscillator. The histogram will also change color based on which threshold TSV has met. This calculation allows us to compare current volatility to the mean (moving average) of the population (Z-Length). The closer the TSV Z-Score is to the mean, the closer it will be to the Zero Line and therefore price is likely consolidating and choppy. The farther TSV Z-Score is from the mean, the more likely price is trending. The MA Mode determines the Moving Average used to calculate TSV itself. The Z-Score is ALWAYS calculated with a simple moving average (as that is the standard calculation for Z-Score). The Threshold Levels are the levels at which TSV Z-Score will change from gray to yellow, orange, green ( bullish ), or red ( bearish ). Statistically speaking, confidence levels in relation to Z-Score are noted below. The built in Threshold Levels are the positive and negative values for 90%, 95%, and 99%. This would indicate when volatility is greater than these values they are out of the ordinary from the standard range. You may wish to adjust these levels for TSV Z-Score to be more responsive to your trading needs 80% :: 1.28 85% :: 1.44 90% :: 1.64 95% :: 1.96 99% :: 2.58 The Z Length is the period for which the Z Score is calculated More information regarding Time Segmented Volume can be found here: www.worden.com Original code ported by @liw0 Corrected by @vitelot Updated/Enhancements by @eylwithsteph with inspiration from @storma Multiple MA Options Credits to @Fractured and @lejmer Bits and Pieces from @AlexGrover, @Montyjus, and @Jiehonglim As always, trade at your own risk.

WhipLashThis is a study to determine if small candle bodies (little difference between open and close), regardless of overall candle length (high/low), can be used to filter choppy markets. The indicator will calculate the selected average "MA Mode" of (close-open). To standardize this result and ensure any filters/thresholds do not need to be recalculated for each instrument the result will be used to calculate the Z Score. The idea is that when candle bodies are small there is very little actual price movement, and therefore price is choppy. When considering the Z Score of that result, any outliers ie larger candle bodies, could show a potential trend forming. This indicator is similar to QStick but allows more customization by the user. MA Mode determines which MA is used to smooth the results of (close-open) Price Smoothing is the number of running periods the MA Mode is calculated for. The three Thresholds are preset to the 90%, 95%, and 99% levels for Z Score. If these thresholds are altered you may wish to also alter the horizontal lines programmed for each level on the positive and negative sides. The Z Length is the period for which the Z Score is calculated Multiple MA Options Credits to @Fractured Bits and Pieces from @AlexGrover, @Montyjus, and @Jiehonglim As always, trade at your own risk.

OBV Z-ScoresThis study calculates the On-Balance Volume (OBV) and displays it in terms of its Z-Score. OBV is a great momentum indicator . As the name suggests, OBV predicts changes in price based on the security's volume flow. Formula: if (Current Price > Previous Price) then Current OBV = Previous OBV + Current Volume if (Current Price < Previous Price) then Current OBV = Previous OBV - Current Volume if (Current Price == Previous Price) then Current OBV = Previous OBV As the formula shows, the OBV goes a step beyond just looking at the pure volume of a security. Instead, it factors in relative price action from period to period to reflect investor sentiment. As a result, we often look to the OBV to spot bullish or bearish trends while they are in the early stages of development or simply predict impending uptrends or downtrends. To make the OBV easier to visualize, we converted the value to a Z-Score. The Z-Score is a simple statistical measurement and represents the current OBV value's distance from the mean OBV value in terms of # of standard deviations. Users can adjust the values for the 2 upper bounds for Z Scores and 2 lower bounds. Additionally, the n value for z score calculation can be adjusted in the input menu. A higher n value means the z score will be based on a longer lookback period. A lower value will result in more sensitive readings. Overall, I think this is an interesting way to represent OBV values and will be a valuable leading indicator. ~Happy Trading~

Multi Z Score [DW]This is an experimental study using z scores of multiple sampling periods to analyze price trends. Z score measures the number of standard deviations price is from its mean. In this study, z scores are calculated over a Fibonacci sequence of sampling periods from 3 to 4181. The scores are then averaged with equal weighting, resulting in a display of long term trend with short term sensitivity. Custom bar colors are included. The color scheme is based on the perceived trend from the average z score.

Z-Score (Close)A Z-score is a numerical measurement of a value's relationship to the mean in a group of values. If a Z-score is 0, it represents the score as identical to the mean score. Z-scores may also be positive or negative, with a positive value indicating the score is above the mean and a negative score indicating it is below the mean. Positive and negative scores also reveal the number of standard deviations that the score is either above or below the mean.
