Technical Analysis

ABANDS

Acceleration Bands (ABANDS) created by Price Headley. Plots bands around a simple moving average as the midpoint and the upper and lower bands are of equal distance from this midpoint. Look for breakouts outside these bands, while also using the shorter time frames to define likely support and resistance levels at the lower and upper Acceleration Bands. This indicator is usually plotted on the price chart.

• ABANDS(high, low, close, period)

Returns an array with 3 results arrays. Upper on index 1, middle on index 2 and lower on index 3.

AD

Accumulation/Distribution Line (AD) Developed by Marc Chaikin, the Accumulation Distribution Line is a volume-based indicator designed to measure the cumulative flow of money into and out of a security. Chaikin originally referred to the indicator as the Cumulative Money Flow Line. As with cumulative indicators, the Accumulation Distribution Line is a running total of each period's Money Flow Volume. First, a multiplier is calculated based on the relationship of the close to the high-low range. Second, the Money Flow Multiplier is multiplied by the period's volume to come up with a Money Flow Volume. A running total of the Money Flow Volume forms the Accumulation Distribution Line. This indicator is usually plotted to its own chart.

• AD(high, low, close, volume)

Returns the AD result.

ADOSC

Developed by Marc Chaikin, the Chaikin Oscillator (ADOSC) measures the momentum of the Accumulation Distribution Line using the MACD formula. (This makes it an indicator of an indicator.) The Chaikin Oscillator is the difference between the 3-day and 10-day EMAs of the Accumulation Distribution Line. Like other momentum indicators, this indicator is designed to anticipate directional changes in the Accumulation Distribution Line by measuring the momentum behind the movements. A momentum change is the first step to a trend change. This indicator is usually plotted to its own chart.

BETA

The Beta (BETA) value can measure he volatility of a coin in relation to that of the market. For stock investors the beta value[1] of a portfolio is an important measure of risk, a value above 1 means the investment is more volatile than the market, a value lower than 1 is less volatile. It can be helpful to do a beta analysis for your portfolio to see how returns match up against the beta and spot real winners (low beta, high returns). Since most altcoins are still sold and bought using Bitcoin (BTC), its price could be used as the [Market's source data] (2nd input parameter), which results BTC a beta of 1. This indicator is usually plotted to its own chart.

KELTNER

The Keltner Channel (KELTNER), originally developed by Chester Keltner, extended by Linda Bradford Raschke, uses a volatility-based envelopes set above and below an exponential moving average. This indicator is similar to Bollinger Bands, which use the standard deviation (STDDEV) to set the bands. Instead of using the standard deviation, Keltner Channels use the Average True Range (ATR) to set channel width. The channels are typically set 2x ATR values above and below the EMA. The exponential moving average dictates direction and the Average True Range sets channel width. Keltner Channels are a trend following indicator used to identify reversals with channel breakouts and channel direction. Channels can also be used to identify overbought and oversold levels when the market is ranging. This indicator is usually plotted on the price chart.

• KELTNER(high, low, close, emaPeriod, [ atrPeriod ], [ multiplier ])

KST

Know Sure Thing (KST), developed by Martin Pring, is a momentum oscillator based on the smoothed Rate-of-Change (ROC) for four different periods. In short, KST measures price momentum for four different price cycles, combining them into a single momentum oscillator. Like any other unbound momentum oscillator, chartists can use KST to look for divergences, signal line crossovers, and centerline crossovers. Pring frequently applied trend lines to KST. Although trend line signals do not occur often, Pring notes that such breaks reinforce signal line crossovers. This indicator is usually plotted on its own chart.

MAMA

The Mesa Adaptive Moving Average (MAMA) is a trend-following indicator which adapts to price movement "based on the rate change of phase as measured by the Hilbert Transform Discriminator". This method of adaptation features a fast and a slow moving average so that the composite moving average swiftly responds to price changes and holds the average value until the next bar’s close. The Averages act as support and resistance areas and the price will tend to react to them. This makes pullbacks to the MAMA and FAMA suitable with-trend entry areas. This indicator is usually plotted on the price chart. NOTE: The FastLimit and SlowLimit parameters should be between 0.01 and 0.99.

• MAMA(prices, fastlimit, slowlimit)

MFI

The Money Flow Index (MFI), developed by Gene Quong and Avrum Soudack, is an oscillator that uses both price and volume to measure buying and selling pressure. MFI is also known as volume-weighted RSI. MFI starts with the typical price for each period. Money flow is positive when the typical price rises (buying pressure) and negative when the typical price declines (selling pressure). A ratio of positive and negative money flow is then plugged into an RSI formula to create an oscillator that moves between zero and one hundred. As a momentum oscillator tied to volume, MFI is best suited to identify reversals and price extremes with a variety of signals.

TRIMA

The Triangular Moving Average (TRIMA) is similar to other moving averages in that it shows the average (or mean) price over a specified number of data points (usually a number of price bars). However, the triangular moving average differs in that it is double smoothed — which also means it is averaged twice. This indicator is usually plotted on the price chart.

TSF

Time Series Forecast (TSF) is a linear regression calculation that plots each bar’s current regression value using the least square fit method. This indicator is sometimes referred to as a moving linear regression similar to a moving average. For example, the TSF value that covers 10 days will have the same value as a 10-day Time Series Forecast. This differs slightly from the Linear Regression indicator in that the Linear Regression indicator does not add the slope to the ending value of the regression line. This indicator is usually plotted on the price chart.

UDRSI

The UpDown RSI (UDRSI) is an RSI Based Indicator that uses an alternative formula to calculate the momentum oscillator. This Indicator works exactly like RSI but instead of determining this from the difference in price, it is calculated by what is called trend stepping. Trend stepping basically measures the closing price of a range of candles and when the price of one candle is lower than the next, it is calculated as 1 price step up. Because of this alternative calculation of Relative Strength Index, Up Down RSI produces some unique Trade Signals.

• UDRSI(prices, period)

Returns the UDRSI result.

ULTOSC

The Ultimate Oscillator (ULTOSC), developed by Larry Williams, is a momentum oscillator designed to capture momentum across three different timeframes. The multiple timeframe objective seeks to avoid the pitfalls of other oscillators. Many momentum oscillators surge at the beginning of a strong advance, only to form a bearish divergence as the advance continues. This is because they are stuck with one timeframe. The Ultimate Oscillator attempts to correct this fault by incorporating longer timeframes into the basic formula. Williams identified a buy signal a based on a bullish divergence and a sell signal based on a bearish divergence.

• ULTOSC(high, low, close, periodA, periodB, periodC)

Returns the ULTOSC result.

WiMA

Wilder Moving Average (WiMA), also called Wilder's Smoothed Moving Average, is similar to the Exponential Moving Average. Compared to other moving averages, Wilders MA responds more slowly to price changes, where an n-period Wilder MA gives similar values to a 2n- period EMA. For example, a 14-period EMA has almost the same values as a 7-period Wilder MA.

ZLEMA

The Zero-Lag Exponential Moving Average (ZLEMA), developed by John Ehlers and Ric Way. As is the case with the double exponential moving average (DEMA) and the triple exponential moving average (TEMA) and as indicated by the name, the aim is to eliminate the inherent lag associated to all trend following indicators which average a price over time. The idea is do a regular exponential moving average (EMA) calculation but on a de-lagged data instead of doing it on the regular data. Data is de-lagged by removing the data from "lag" days ago thus removing (or attempting to) the cumulative effect of the moving average.

• ZLEMA(prices, period)

Returns the ZLEMA result.

ZLMA

The Zero Lag Moving Average (ZLMA) is the same as ZLEMA, but opens up the possibility to change the type of the moving average. The idea is do a regular moving average (MA) calculation but on a de-lagged data instead of doing it on the regular data. Data is de-lagged by removing the data from "lag" days ago thus removing (or attempting to) the cumulative effect of the moving average.
