Does RSI Follow a Normal Distribution? The value of RSI was converted to a value between 0~2, 2~4, ..., 98~100, and the number of samples was graphed. The Z values are expressed so that the values corresponding to 30 and 70 of the RSI can be compared with the standard normal distribution. Additionally, when using the RSI period correction function of the 'RSI...

The Return Abnormality Score indicator is designed to help traders identify potential reversals in price by detecting abnormal daily returns beyond a certain significance level. The indicator uses a normal cumulative distribution function to calculate the probability of the daily return and flags it when it exceeds the specified significance level. Traders can...

This indicator shows the expected range of movement of price given the assumption that price is log-normally distributed. This includes 3 multiples of standard deviation and 1 user selected level input as a multiple of standard deviation. Expected assumes that volatility remains static on the next bar. In reality, this may or may not be the case, so use caution...

Library "normsinv" Description: Returns the inverse of the standard normal cumulative distribution. The distribution has a mean of zero and a standard deviation of one; i.e., normsinv seeks that value z such that a normal distribtuion of mean of zero and standard deviation one is equal to the input probability. Reference: github.com normsinv(y0)...

Library "norminv" Description: An inverse normal distribution is a way to work backwards from a known probability to find an x-value. It is an informal term and doesn't refer to a particular probability distribution. Returns the value of the inverse normal distribution function for a specified value, mean, and standard deviation. Reference: ...

One-Sided Gaussian Filter w/ Channels is a Gaussian Moving Average that is calculated using a Fibonacci weighting function. Keltner channels have been added to show zones of exhaustion. A better name would be "Half Gaussian bell weighted" or "Half normal distribution weighted" indicator, since the weights for calculation of the average (similar to linear...

Bollinger Bands are the result of the assumption that closing prices will follow a normal distribution. However, when I actually calculated the probability, the closing price does not follow a normal distribution. According to the normal distribution, the probability that Z > 2 should be 2.2%, but on the chart, the probability is 6~9%. Can we get a useful...

Probability Distribution Histogram During data exploration it is often useful to plot the distribution of the data one is exploring. This indicator plots the distribution of data between different bins. Essentially, what we do is we look at the min and max of the entire data set to determine its range. When we have the range of the data, we decide how many...

The exa is an oscillator that combines fisher transform with distance from moving average and it is based on a theory that exhaustion can be derived from how far price is able to extend from a moving average, on average. The fisher transform converts price into a gaussian normal distribution, also known as a bell curve {1}. A normal distribution is a type of...

The Impossible RSI is built on original RSI. If users want traditional RSI value, they can choose "Traditional RSI" in RSI mode. Untick "Log transform" ,"Error Correcting Smoothing " and "show columns" options in settings. Orginal RSI allows negative price as input. By using the log transform on input price, we eliminate the negative price scenario. The...

Mom is a momentum indicator calculated based on the EWMA historical volatility. It calculates the difference between the upward volatility and downward volatility. An advanced smoothing technique is used to smooth the indicator for people who want to get rid of noises. It has error-correcting property and limits overshoot. The lag is limited while still...

Volatility bands based on average candle percentage spread. Tested on BTCUSD charts only. Based on the 68-95-99.7 rule, it seems that the spread, for daily and 4-H candles, follows a normal distribution: that means, around 85% of candles have a %-spread within sma(low/high, some_len) and sma(high/low, some_len) , and around 95% of candles within the pow2 of...
