## RSI: Relative Strength Index

The Relative Strength Index (RSI) calculates a ratio of Rsi指标最早是被用于期货交易中 the recent upward price movements to the absolute price movement. Developed by J. Welles Wilder.

## Usage

## Arguments

Price series that is coercible to xts or matrix.

Number of periods for moving averages.

A function or a string naming the function to be called.

A *list* with the first component like (1) above, and additional parameters specified as *named* components. See Examples.

Other arguments to be passed to the *Rsi指标最早是被用于期货交易中* maType function in case (1) above.

## Value

A object of the same class as price or a vector (if try.xts fails) containing the RSI values.

## Details

The RSI calculation is RSI = 100 - 100 / ( 1 + RS ) , where RS is the smoothed ratio of 'average' gains over 'average' losses. The 'averages' aren't true averages, since they're divided by the value of n and not the number of periods in which there are gains/losses.

## MFI-RSI

I present you the chart oscillator where an oscillator (Stoch or RSI) is plotted on the chart itself (instead of below the chart) It is inspired on an idea of @Kablamicus Instead of having the lines between 0 and 100, here the '0-100' are - lowest(low, len) - highest(high, len) An overbought/oversold and a middle line is derived from these **Rsi指标最早是被用于期货交易中** lines and the.

Combines: Relative Strength (purple) and RSI Stoch (Orange/gray), Money Flow (green) all in one indicator window. On screen indicator text identifier will read in this order: "RSI/STOCH/MFI V3" // Changes from original version \\ It was important to bring forth the RSI indicator as the most visually important line and its relationship to the background. A.

The signals are based on the Gaussian Channel calculated by Donovan Wall. Thanks also to Kiasaki for Rate of Change code. Simply going long and short based on Gaussian channel was not consistent enough so I also included an MFI filter. We only go long if Money Flow Index is greater than the last candle (more money is **Rsi指标最早是被用于期货交易中** flowing in than out). The opposite for short.

Bill Williams indicator (MFI). The indicator calculates the range of oscillations per unit volume. In fact, this indicator shows the tick volume or the readiness of the market to move the **Rsi指标最早是被用于期货交易中** price. The indicator is presented as vertical columns or as a line with *Rsi指标最早是被用于期货交易中* levels. Vertical columns are painted in different colors depending on the displacement of Rsi指标最早是被用于期货交易中 the indicator.

## Stochastic RSI (STOCH RSI)

The Stochastic RSI indicator (Stoch RSI) is essentially an indicator of an indicator. It is used in technical analysis to provide a stochastic Rsi指标最早是被用于期货交易中 calculation to the RSI indicator. This means that it is a measure of RSI relative to its own high/low range over a user defined period of Rsi指标最早是被用于期货交易中 time. The Stochastic RSI is an oscillator that calculates a value between 0 and 1 which is then plotted as a line. This indicator is primarily used Rsi指标最早是被用于期货交易中 for identifying overbought and oversold conditions.

#### History

The Stochastic RSI (Stoch RSI) indicator was *Rsi指标最早是被用于期货交易中* developed by Tushard Chande and Stanley Kroll. They introduced their indicator in their 1994 book The New Technical Trader.

#### Calculation

#### In this example, a very common 14 Period Stoch RSI is used. Here are some approximate benchmark levels:

#### The basics

It is important to remember that the Stoch RSI is an indicator of an indicator making it two steps away from price. RSI is one step away from price and therefore a stochastic calculation of the RSI is two steps away. This Rsi指标最早是被用于期货交易中 is important because as with any indicator that is multiple steps away from **Rsi指标最早是被用于期货交易中** Rsi指标最早是被用于期货交易中 price, Stoch RSI can have brief disconnects from actual price movement. That being said, as a range bound indicator, the Stoch RSI's primary function is identifying crossovers as well as overbought and oversold conditions.

#### What to look for

##### Overbought/Oversold

Overbought and Oversold conditions are traditionally different than the RSI. While RSI overbought and oversold conditions are traditionally set at 70 for overbought and 30 for oversold, Stoch RSI are typically .80 and .20 respectively. When using the Stoch RSI, overbought and oversold work best when trading along with the underlying trend.

During an uptrend, look for oversold conditions for points of entry.

During a downtrend, look for overbought conditions for points of entry.

#### Summary

When using Stoch RSI in technical analysis, a trader should be careful. By adding the Stochastic calculation to RSI, speed is greatly increased. This can generate many more signals and therefore more bad signals as well as the good ones. Stoch RSI needs to be combined with **Rsi指标最早是被用于期货交易中** Rsi指标最早是被用于期货交易中 additional tools or indicators in order to be at its most effective. Using trend lines or basic chart pattern analysis can help to identify major, underlying trends and increase the Stoch RSI's accuracy. Using Stoch RSI to make trades that go against the underlying trend is a dangerous proposition.

#### Inputs

The time period to be used in calculating the %K. 3 is the default.

% D = Percent of Deviation between price and the average of previous prices (Momentum). The time period to be used in calculating the %D. 3 is the Rsi指标最早是被用于期货交易中 default.

##### RSI Length

The time period to be used in calculating the RSI

##### Stochastic Length

The time Rsi指标最早是被用于期货交易中 period to be used in calculating the Stochastic

##### RSI Source

Determines what data from each Rsi指标最早是被用于期货交易中 bar will be used in calculations. Close is the default.

#### Style

Can toggle the visibility of the %K as well as the visibility of a price line Rsi指标最早是被用于期货交易中 showing the actual current value of the %K. Can also select the %K Line's color, line thickness and visual style (Line is the Default).

Can toggle the visibility of the %D as well as the visibility of a price line showing the actual current value of the %D. Can also select the %D Line's color, line thickness and visual style (Line is the Default).

##### Upper Band

Can toggle the visibility of a line indicating overbought levels. Can also select Rsi指标最早是被用于期货交易中 the line’s value, line thickness, value and visual type (dashes is the default).**Rsi指标最早是被用于期货交易中**

##### Lower Band

Can toggle the visibility of a line indicating oversold levels. Can also select the line’s value, line thickness, value and visual type (dashes is the default).Rsi指标最早是被用于期货交易中

##### Background

Toggles the visibility of a Background color within the Bands. Can also change the Color itself as well as the opacity.

##### Precision

Sets the number of decimal places to be left on the indicator's value before rounding up. The higher this number, the more decimal points will be on the indicator's value.
