RS.ROC | Relative Strength - Rate of Changes - 4CR CUPFor completeness of Relative Strength studies, the Relative Strength based on rate of changes (ROC) with weighting is coded and presented as well. The RS.ROC is similar to the formulation of RS by IBD before rank among all the stocks in the market. The lookback period is relaxed for customizing. Once you set the total lookback period, representing the 4Q, in the indicator, the other shorter lookback periods will be auto-calculated, namely, 1Q, 2Q, 3Q. A simple moving average of the RS.ROC is also added for your easier analysis on the trend development of the strength. To use it later at your charting later, 1. Favorite it; 2. Select from your favorite list.

Nick Rypock Trailing Reverse (NRTR)This indicator was invented in 2001 by Konstantin Kopyrkin. The name "Nick Rypock" is derived from his surname reading in the opposite direction: Kopyrkin -> Kopyr Kin -> Kin Kopyr -> Nik Rypok The idea of the indicator is similar to the Chandelier Exit, but doesn't involve ATR component and uses a percentage instead. A dynamic price channel is used to calculate the NRTR. The calculations involve only those prices that are included in the current trend and exclude the extremes related to the previous trend. The indicator is always at the same distance (in percent) from the extremes reached by prices (below the maximum peak for the current uptrend, above the minimum bottom for the current downtrend).

MegaChangeThe MegaChange indicator is a traditional Change - on steroids! This indicator visualizes the Change from the current bar to the one before. Besides showing the standard change (% change from the previous bar's Last to current bar's Last), the indicator also includes the % change from the previous bar's Last to current bar's High, and to current bar's Low. The result is always in percentage. "green" days and "red" days are separated so you can always see on the scales the change for the last green day and the change for the last red day (only one of whom is the current change). The indicator demonstrates "how far" the change has gone each way, and where is it currently. Here's an example, using the chart above: When we look at the big red candle we might see it as a very bad sign. (With the blue bubble next to it) When we examine that candle with this indicator - the MegaChange - we can observe that the downside is very small in comparison to the Upside that came before that. (Tagged as 1) On the next candle (Tagged as 2) we can see a small tail representing the stock price going down and coming most of the way back. returning from -16% to only -4% after moving more than +170% only 2 days earlier! This might mean that the buyers are coming back and they're chasing the stock again for another run (long). This is an example of how the indicator might indicate future moves, when we might think the move is already over. Looking at the chart alone might be frightening, but using the indicator makes a change, as we can see that's the downside was really small relative to the upside. The small tail from the last day might tell us that the buyers are coming back, and that the stock might still have a potential Upside. fill free to ask any questions, or tell me if you find this indicator helpful, and how.

Logistic RSI, STOCH, ROC, AO, ... by DGTExperimental attemt of applying Logistic Map Equation for some of widly used indicators. With this study "Awesome Oscillator (AO)", "Rate of Change (ROC)", "Relative Strength Index (RSI)", "Stochastic (STOCH)" and a custom interpretation of Logistic Map Equation is presented Calculations with Logistic Map Equation makes sense when the calculated results are iterated many times within the same equation. Here is the Logistic Map Equation : Xn+1 = r * Xn * (1 - Xn) Where, the value of r is the key for this equation which changes amazingly the behaviour of the Logistic Map. The value we have asigned for r is less then 1 and greater than 0 ( 0 < r < 1) and in this case the iterations performed with the maximum number of output series allowed by Pine is quite enough for our purpose and thanks to arrays we can easiliy store them for further processing What we have as output: Each iteration result is then plotted (excluding plotting the first iteration), as circles or line based on user preference Values above and below zero level (0) are coloured differently to emphasis bull and bear power Finally Standard Deviation of Array's Elements is ploted as line. Users may choose to display this line only So where it comes the indicators "Awesome Oscillator (AO)", "Rate of Change (ROC)", "Relative Strength Index (RSI)", "Stochastic (STOCH)". Those are the indicators whose values are assigned to our key varaiable in the Logistic Map equation forulma which is r Further details regarding Logistic Map can found under the description of “Logistic EMA w/ Signals by DGT” study Disclaimer: Trading success is all about following your trading strategy and the indicators should fit within your trading strategy, and not to be traded upon solely The script is for informational and educational purposes only.

Higher High / Lower Low StrategyThis is a very simple trend following strategy for Day Trading. The premise is to follow the Moving Average for the trend direction and buy/sell the dips and blips in the trend. 1. In an uptrend, when the candle action offers a "dip", or a lower high, the strategy will then buy on the close of the candle that breaks the high of the previous candle. 2. In a downtrend, when the candle action offers a"blip", or a higher low, the strategy will then sell on the close of the candle that breaks the low of the previous candle. 3. The strategy will go Long only or Short only, not both. It must be manually reversed in the settings when a new trend is established. 4. The start month and year allow you to backtest from then until now. It's not one month at a time. 5. The strategy uses a reversal of the Stochastic %K variable as the exist. The setting for Period K controls the exit for backtesting purposes. 6. The strategy uses a moving average to determine the trend. The setting for the Period MA controls the SMA. 7. The strategy has the option of filtering the number of trades based on the direction of the MACD and/or the Signal line. This can either reduce or increase the probability, and is highly dependent on the price action of the instrument. WARNING: I am not a licensed financial advisor.

ATR draw on the candle easily setup SL&TPHi,Guys, Build-in ATR need to read the pips then add on current price to setup safe SL. But under stress of trading, calculation is not effective. Input: Length:Length of ATR n:n*ATR=Risk m:m*Risk=TP the dash line means current price plus n*ATR and minus n*ATR for setup sell or buy stop loss. If increase m more than 1,you can see the additional line outside the original line in order to setup TP with Reward:Risk more than 1. Hope you guys enjoy it, and welcome to comment.

Momentum Acceleration by DGTItalian physicist Galileo Galilei is usually credited with being the first to measure speed by considering the distance covered and the time it takes. Galileo defined speed as the distance covered during a period of time. In equation form, that is v = Δd / Δt where v is speed, Δd is change in distance, and Δt is change in time. The Greek symbol for delta, a triangle (Δ), means change. Is the speed getting faster or slower? Acceleration will be the answer, acceleration is defined as the rate of change of speed over a set period of time, meaning something is getting faster or slower. Mathematically expressed, acceleration denoted as a is a = Δv / Δt , where Δv is the change in speed and Δt is the change in time. How to apply in trading Lets think about Momentum, Rate of Return, Rate of Change all are calculated in almost same approach with Speed Momentum measures change in price over a specified time period, Rate of Change measures percent change in price over a specified time period, Rate of Return measures the net gain or loss over a specified time period, And Speed measures change in distance over a specified time period So we may state that measuring the change in distance is also measuring the change in price over a specified time period which is length, hence speed can be calculated as (source – source )/length and acceleration becomes (speed – speed )/length In this study acceleration is used as signal line and result plotted as arrows demonstrating bull or bear direction where direction changes can be considered as trading setups Just a little fun, since we deal with speed the short name of the study is named after famous cartoon character Speedy Gonzales Trading success is all about following your trading strategy and the indicators should fit within your trading strategy, and not to be traded upon solely Disclaimer: The script is for informational and educational purposes only.

US Inflation Rate [nb]This is the United States inflation rate, based on the total Consumer Price Index published by the U.S. Bureau of Labor Statistics. Option to toggle: A line to display the inflation rate in December. It does not change until the next December. What the color change to red is indicative of: According to the Federal Open Market Committee (FOMC) regarding inflation rate, "2% is a bae number to be around". This does not imply a strict 2% inflation for success and allows room for federal rate cuts should they be needed. Although FOMC declared 2% to be "bae" in 2012, James Bullard, of federal banking fame, claims that started to become the norm in 1995. Therefore the inflation rate line will only turn red 1995 onwards, and serves as a friendly reminder that inflation has been over at or over 2% for more than one month.

Rate Of Change - Weekly SignalsRate of Change - Weekly Signals This indicator gives a potential "buy signal" using Rate of Change of SPX and VIX together, using the following criteria: SPX Weekly ROC(10) has been BELOW -9 and now rises ABOVE -5 *PLUS* VIX Weekly ROC(10) has been ABOVE +80 and now falls BELOW +10 The background will turn RED when ROC(SPX) is below -9 and ROC(VIX) is above +80. The background will turn GREEN when ROC(SPX) is above -5 and ROC(VIX) is below +10. So the potential "buy signal" is when you start to get GREEN BARS AFTER RED - usually with some white/empty bars in between...but wait for the green. This indicates that the volatility has settled down, and the market is starting to turn up. This indicator gives excellent entry points, but be careful of the occasional false signals. See Nov. 2001 and Nov. 2008, in both cases the market dropped another 25-30% before the final bottom was formed. Always have an exit strategy, especially when buying in after a downtrend. How I use this indicator, pretty much as shown in the preview. Weekly SPX as the main chart with some medium/long moving averages to identify the trend, VIX added as a "Compare Symbol" in red, and then the Weekly ROC signals below. For the ROC graphs, you can show SPX+VIX together, SPX alone, or VIX alone. I prefer to display them separately because they don't scale well together (VIX crowds out the SPX when it spikes). Background color is still based on both SPX/VIX together, regardless of which graph is shown. Note that there is no VIX data available on Trading View prior to 1990, so for those dates the formula is using only ROC(SPX) and the assigned thresholds (-9 and -5, or whatever you choose).

COVID-19: Daily change per capita (EU only)New confirmed cases per day (daily change) is one thing, just an absolute value but when we put this number in context of population (per million people) of each country the situation is a bit different. We can easily see that, at the moment (Apr 2nd, 2020), the most affected country is Spain (~150 new cases per million people per day) and surprisingly the second one is Switzerland (CH). We can also see Spain or Belgium's steep curve relative to other countries. I know that some countries run more tests than the others and the outcome might not be reflect the reality but this is the official data that is available.

COVID-19: Daily momentumThis indicator shows 14-days moving average of daily rate of change (momentum, acceleration), in other words: - up trends means that virus accelerates at the rate displayed on the right scale - consolidation/horizontal movement - virus spreads at constant rate - down trend - virus looses momentum IMPORTANT: the virus STILL accelerates but at a lower rate By default the graphic displays World vs. EU vs. US vs. Asia while individual countries are available in Settings. - EU includes the following countries (DE, FR, IT, ES, CH), all with more than 10k confirmed cases and more than 1k new daily infections. - Asia includes CH and KR To use the indicator it is important to disconnect main chart from the right scale, on main chart click on More (the 3 dots) -> Pin to scale -> Select "No Scale".

GMS: RSI & ROC StrategyThis is a basic strategy like the RSI one I posted. This one adds in the Rate of Change indicator as well. You can separate the two for RSI only and ROC only. Everything else is the same as the RSI strategy. - Simple moving average trend filter. - Simple moving average trade exit. - Both long and short or each on it's own. The source code should be open if you want to see it or modify it for your own project. I hope it helps! Andre Global Market Signals

SMU Binary Decimal CandlesThis script creates a Decimal and Binary representation of the price using ROC. The idea is to simplify the price action into a distance from Zero to upside and downside. You can see clearly trend develops in the ROC in the decimal view, kind of like MACD but based on raw price action change. I'm' a big fan of raw price action, so my scripts are super simple. You can also use this script in a binary mode close higher = 1 and lower is -1. I use the binary mode to remove the psychological pressure of watching the stock going against me. I turn off the actual price and only focus on number of reds vs blue. On a Quantum physics level, when I short, I observe /wish for more reds like last night 1% sell-off The main message form all my scripts is think outside the box, experiment with something crazy that doesn't make sense at first and make it to make sense. I always start with an idea that pops into my head, script with Pine script super simple and then watch it for hours to see what is trying to tell me. I have many work in progress that still doesn't make sense but looks really weird and wonderful. When I figure out what is trying to tell me I publish it

Rate Of Change Earnings Move - ROCEMRate Of Change Earnings Move What is it and how does it work? The Rate of Change Earnings Move indicator or ROCEM is an indicator designed for giving the user an idea of how much a stock has moved up or down in past earnings reports. This is ideal for options traders who can use ROCEM to calculate whether or not their long straddles are actually probable of happening. How it works The indicator measures the absolute value rate of change and then calculates the average rate of change for the day of the earnings report for the past 8 earnings reports (2 years). It then takes the current stock price and finds the upper and lower price based on the average rate of change for past earnings. I have also included a moving average (purple line), use this to see if the current rate of change is higher than usual. Additionally, earnings reports are marked with a red x on the indicator. How to trade ROCEM This is primarily made for options trading so I will be explaining how it can be used for that. It is not suited for traditional stock trading as it does not determine a market direction. Select a stock with an upcoming earnings Enter your per leg commissions in the indicator if you want it to calculate new upper and lower prices (makes it easier to determine if the options trade will pass the breakeven when commissions are factored in) Compare your long straddle breakevens with the upper and lower prices of the indicator. If the upper breakeven is smaller than the upper price in ROCEM and the lower breakeven is larger than the lower price in ROCEM, then a long straddle position could be considered a reasonable trade based on past earnings performance.
