Super EMA PrismThis script implements the Binary Trade Logic (BTL) algorithm to calculate two distinct scores that range from 0 to 7. One score is calculated assigning a power of 2 weight to the positive sign of 3 Phi^3 distant Moving Average (MA) slopes. The other score is calculated assigning a power of 2 weight to the sign of the difference between the price and the value of 3 Phi^3 distant Moving Average (MA). For the first score, hereafter called as the angle score (AS), the largest MA slope positive sign receives weight 4, the middle length MA slope positive sign receives weight 2 and the shortest MA slope positive sign receives weight 1. The positive sign of an MA is defined as 1 if the slope of the MA is positive and 0, otherwise. Therefore, for MAs 305, 72 and 17, if slope(MA305) > 0, slope(MA72) < 0 and slope(MA17) > 0, then score will be 4*1 + 2*0 + 1*1 = 5. Up to my knowledge, this score was first proposed by Bo Williams and named by him as Prisma. For the second score, hereafter called as the value score (VS), if the price > largest MA, it receives weight 4. If the price > the middle length MA, it receives weight 2 and if the price > the the shortest MA, it receives weight 1. Therefore, for MAs 305, 72 and 17, if price < MA305, price > MA72 and price > MA17, then score will be 4*0 + 2*1 + 1*1 = 3. Up to my knowledge, this score was first proposed by Bo Williams and named by him as Prisma. Both AS and VS are calculated for Phi^3 lengths (610, 144, 34) and for Phi^3/2 lengths (305, 72, 17). The scores of the same kind calculated for each set of length are combined multiplying the Phi^3 length score by 10 and adding with with the Phi^3/2 score, therefore providing a 2 digit score ranging from 0 to 77. For instance, if we have AS(610, 144, 34) = 7 and AS(305, 72, 17) = 5, we have AS=75. At the same time, if we have VS(610, 144, 34) = 6 and VS(305, 72, 17) = 4, we have VS=64. VS score is plotted by default in black, but it can be on white for dark themes. AS is plotted with the color of the longest MA used. Chart background is colored according to the range of values for AS and VS, checked in the following order: if AS >= 13 and VS <= 13 then back color = red if AS >= 13 or VS <= 13 then back color = orange if AS >= 64 and VS >= 64 then back color = green if AS >= 64 or VS >= 64 then back color = blue otherwise back color = none (white o black)

Custom EMA PrismThis script implements the Binary Logic Trading (BLT) algorithm to calculate a score from 0 to 7. This score is calculated assigning a power of 2 weight to the positive sign of 3 Phi^3 distant EMAs' slopes. The largest EMA slope positive sign receives weight 4, the middle length EMA slope positive sign receives weight 2 and the shortest EMA slope positive sign receives weight 1. The positive sign of an EMA is defined as 1 if the slope of the EMA is positive and 0, otherwise. Therefore, for EMAs 305, 72 and 17, if slope(EMA305) > 0, slope(EMA72) < 0 and slope(EMA17) > 0, then score will be 4*1 + 2*0 + 1*1 = 5. Up to my knowledge, this score was first proposed by Bo Williams and named by him as Prisma. Due too sampling issues, this script ONLY WORKS with graphic time of 1d. I would like to thanks to MrBitmanBob for showing me how to get quotations from a graphic time distinct from the current one. This script also gets sampling data from graphic times 2h and 30m to calculate their score. As, even for smaller graphic times, price data is sampled at the current time frequency, the EMA lengths for those smaller graphic times needed to be proportionally decreased, meaning that when calculating the score for 1d with lengths 305, 72 and 17, the score for 2h must be calculated with lengths 72, 17 and 4, and the score for 30m must be calculated with lengths 17, 4 an 1. I understand that some precision may be lost but it is the best that is possible. There is an optional setting for Crypto Currencies that instead of calculating the score for 1d, 2h and 30m, it calculates the score for 1d, 4h and 60m. This is due to the fact that Crypto Currencies are traded 24x7. Despite of this setting, the labels at the Style tab of the settings window remains 2h and 30m, because they must be constants. This script with the corresponding EMAs chart and the EMAs Angle chart provides a broader view of the trading scenario.

Custom EMA AngleThis script shows the angle of 6 EMAs to perform trade analysis. The EMA angle is also known as its Rate Of Change ( ROC ). The 6 EMAs (I, II, III , IV, V and VI ) default lengthes come from one of the Fibonacci Phi^3 and Phi^3/2 sub series (17, 34, 72, 144, 305 and 610), but can be changed to any values, particularly to the traditionally used 20, 40, 50, 100, 200 and 300. Up to my knowledge, Fibonacci Phi^3 and Phi^3/2 sub series lengthes were first proposed by Bo Williams. Angle calculation is performed by calculating the tangent over a delta interval. Normalization is required to make the angle independent of the price range. This script is meant to be used together with the corresponding EMAs on the candle pane. Non normalized view shows a more realistic angle condition but, if intended to be used with the CEMAS indicator, normalized view should be used.

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.

Decaying Rate of Change Non Linear FilterThis is a potential solution to dealing with the inherent lag in most filters especially with instruments such as BTC and the effects of long periods of low volatility followed by massive volatility spikes as well as whipsaws/barts etc. We can try and solve these issues in a number of ways, adaptive lengths, dynamic weighting etc. This filter uses a non linear weighting combined with an exponential decay rate. With the non linear weighting the filter can become very responsive to sudden volatility spikes. We can use a short length absolute rate of change as a method to improve weighting of relative high volatility. c1 = abs(close - close ) / close Which gives us a fairly simple filter : filter = sum(c1 * close,periods) / sum(c1,periods) At this point if we want to control the relative magnitude of the ROC coefficients we can do so by raising it to a power. c2 = pow(c1, x) Where x approaches zero the coefficient approaches 1 or a linear filter. At x = 1 we have an unmodified coefficient and higher values increase the relative magnitude of the response. As an extreme example with x = 10 we effectively isolate the highest ROC candle within the window (which has some novel support resistance horizontals as those closes are often important). This controls the degree of responsiveness, so we can magnify the responsiveness, but with the trade off of overshoot/persistence. So now we have the problem whereby that a highly weighted data point from a high volatility event persists within the filter window. And to a possibly extreme degree, if a reversal occurs we get a potentially large "overshoot" and in a way actually induced a large amount of lag for future price action. This filter compensates for this effect by exponentially decaying the abs(ROC) coefficient over time, so as a high volatility event passes through the filter window it receives exponentially less weighting allowing more recent prices to receive a higher relative weighting than they would have. c3 = c2 * pow(1 - percent_decay, periods_back) This is somewhat similar to an EMA, however with an EMA being recursive that event will persist forever (to some degree) in the calculation. Here we are using a fixed window, so once the event is behind the window it's completely removed from the calculation I've added Ehler's Super Smoother as an optional smoothing function as some highly non linear settings benefit from smoothing. I can't remember where I got the original SS code snippet, so if you recognize it as yours msg me and I'll link you here.

Function To Candles - Another way to see indicatorsIntroduction There are different and better way's to see price data, a candlestick chart is one of the best way to see the price since you have access to the open/high/low/close information, this is really efficient and can allow for naked non parametric trading strategies (candlesticks patterns) . But what about making candles out of indicators ? There are tons of studies about candlesticks patterns in price data but none (?) about candlestick patterns using indicator data, therefore i made this script in order to show candles from various indicators, i also made an heikin-ashi mode. Rsi To Candles All the indicators are use the open/high/low/close price as input in order to return candles. length control the indicator period. Stochastic To Candles The stochastic oscillator is restrained in a range of 0/100, therefore when equal to 0 or 100 the candles can be flat. Rate Of Change To Candles The rate of change don't distort price as heavily as other indicators since its based on differencing. Center Of Gravity To Candles The center of gravity (cog) is defined from tradingview as "an indicator based on statistics and the Fibonacci golden ratio", its not an indicator i'am familiar with and i don't know if its the same proposed by Elhers. The candles are smooth, high length can flatten the candles heavily making them hard to see. Correlation Oscillator In a range of -1/1 this indicator is quite smooth and can also flatten candles. Patterns And Heikin-Ashi There are tons of patterns that can be generated from candlesticks, they can be applied to this indicator as well. The indicator can show an heikin-ashi mode, heikin-ashi candlestick use averaging to plot candles, this is why they appear smoother, some signals generated from heikin-ashi candles are : Bullish body with no lower shadows = Strong Uptrend Bearish body with no higher shadows = Strong Downtrend High range and small body = Indecision/Risk of reversal Conclusion I made an indicator able to draw candles from other indicators, those candles contain various information that can generate decision from patterns. I hope you find a use to it, if its the case share your findings with me, maybe that you will even be able find a new candlestick pattern :) Thanks for reading !

[RESEARCH] Rate of ChangeHello traders and developers! I was wondering how built-in "roc" function in Pine is defined and calculated so I made a little research. I examined 4 samples: 1) "roc" function itself 2) "roc" according to its description 3) price change ratio 4) price percent change ratio The results of the first and fourth samples are identical. So, TV built-in roc(source, length) = 100 * change(source, length) / source . And it's description is incorrect. If you didnt know it - now you know it. Good luck!

RSI based on ROC Backtest This is the new-age indicator which is version of RSI calculated upon the Rate-of-change indicator. The name "Relative Strength Index" is slightly misleading as the RSI does not compare the relative strength of two securities, but rather the internal strength of a single security. A more appropriate name might be "Internal Strength Index." Relative strength charts that compare two market indices, which are often referred to as Comparative Relative Strength. And in its turn, the Rate-of-Change ("ROC") indicator displays the difference between the current price and the price x-time periods ago. The difference can be displayed in either points or as a percentage. The Momentum indicator displays the same information, but expresses it as a ratio. You can change long to short in the Input Settings WARNING: - For purpose educate only - This script to change bars colors.

Forex strength meterCalculates the strength of a particular currency taking into account it's rate of change (% price change in a period) in all correlated and anti-correlated pairs. For instance, when looking for USD strength we will add ROC for USDCAD, USDCHF and USDJPY while subtract AUDUSD, EURUSD, GBPUSD and NZDUSD. After ROC step, one can smooth the result using EMA, or MACD. As the script needs to fetch values from multiple currencies it isn't the fastest one, but it gets its job done. Important: Only major currencies (AUD, CAD, CHF, EUR, GBP, JPY, NZD and USD) are considered.

ROC TideAdds some depth to the traditional rate of change (ROC) indicator. Instead of just having one ROC line with a single lookback period, this takes a minimum lookback period, n , and plots 20 ROC lines with lookback periods of n, 2n, 3n, ..., 20n . These lines will appear green when greater than zero, red when less than zero, and yellow when equal to zero by default. Then it plots the average of those 20 ROC's as a yellow filled area so as to make it easier to see where the balance (or "tide") of the ROC waves are located.
