Acceleration bands (ABANDS)

aws.finspace.timeseries.spark.analytics.abands(tenor, time_col_name, price_col_name, high_col_name, low_col_name)

The Acceleration Bands (ABANDS) created by Price Headley plots upper and lower envelope bands around a simple moving average.

Parameters

Return type Callable[. . . , Column]

Returns pandas/Spark user defined scalar function

Accumulation/Distribution (AD)

aws.finspace.timeseries.spark.analytics.acc_dist_indicator(time_col_name,price_col_name, high_col_name, low_col_name, volume_col_name)

The Accumulation/Distribution (AD) study attempts to quantify the amount of volume flowing into or out of an instrument by identifying the position of the close of the period in relation to that period's high/low range. The volume for the period is then allocated accordingly to a running continuous total. In this indicator, if the divisor, high-low is 0, and hence the current money flow volume is nan, then it means that price, which must fall between high and low is also going to equal high. In that case the numerator is 0 as well which means that the contribution should really be 0 in this case. Hence below we filter the NANs out in the equation. https://www.investopedia.com/terms/a/accumulationdistribution.asp

Chaikin money flow

aws.finspace.timeseries.spark.analytics.chaiken_money_flow_indicator(tenor, time_col_name, price_col_name, high_col_name, low_col_name, vol ume_col_name)

Developed by Marc Chaikin, Chaikin Money Flow measures the amount of Money Flow Volume over a specific period. Money Flow Volume forms the basis for the Accumulation Distribution Line. Instead of a cumulative total, Chaikin Money Flow sums Money Flow Volume for a specific look-back period, typically 20 or 21 days. The resulting indicator fluctuates above/below the zero line just like an oscillator. Chartists weigh the balance of buying or selling pressure with the absolute level of Chaikin Money Flow. Additionally, chartists can look for crosses above or below the zero line to identify changes on money flow.

The term and its formula were developed by psychologist and trader AlexanderElder and published in his 1993 book Trading for a Living. The force index uses price and volume to determine the amount of strength behind a price move. The index is an oscillator, fluctuating between positive and negative territory. It is unbounded meaning the index can go up or down indefinitely.

The study is a trend following indicator that identifies mid-points of historical highs and lows at different lengths of time and generates trading signals similar to that of moving averages/MACD. A key difference between Ichimoku and moving averages is Ichimoku charts lines are shifted forward in time creating wider support/resistance areas mitigating the risk of false breakouts. Learn more.

KAMA will closely follow prices when the price swings are relatively small and the noise is low. KAMA will adjust when the price swings widen and follow prices from a greater distance. This trend-following indicator can be used to identify the overall trend, time turning points and filter price movements.

Keltner in his book How To Make Money in Commodities, and is also explained by Perry Kaufman's book The New Commodity Trading Systems and Methods. Keltner Channels plots three lines, consisting of a exponential moving average (typically of the average price) with upper and lower bands plotted above and below this moving average.The width of the bands is based on a user defined factor applied to the Average True Range, with this result added to and subtracted from the middle moving average line.

aws.finspace.timeseries.spark.analytics.klinger_oscillator_indicator(short_period, long_period, time_col_name, price_col_name, high_col_name, low_col_name, volume_col_name)

The indicator was developed by Stephen Klinger to determine the long-term trend of money flow while remaining sensitive enough to detect short-term fluctuations. The indicator compares the volume flowing through securities with the security price movements and then converts the result into an oscillator. The Klinger oscillator shows the difference between two moving averages which are based on more than price. Traders watch for divergence on the indicator to signal potential price reversals. Like other oscillators, a signal line can be added to provide additional trade signals.

Triple exponential moving average (T3)

aws.finspace.timeseries.spark.analytics.t3_ema_indicator(tenor, time_col_name, price_col_name)

The Triple Exponential Moving Average (T3) by Tim Tillson attempts to offers a moving average with better smoothing then traditional exponential moving average.

EMA1 = EMA(x,Period) EMA2 = EMA(EMA1,Period) GD = EMA1*(1+vFactor)) - (EMA2*vFactor) T3 = GD (GD ( GD(t, Period, vFactor), Period, vFactor), Period, vFactor)

Where vFactor is a volume factor between 0 and 1 which determines how the moving averages responds. A value of 0 returns an EMA. A value of 1 returns DEMA. Tim Tillson advised or preferred a value of 0.7.

Parameters

Return type Callable[. . . , Column]

Returns pandas/Spark user defined scalar function

Time series forecast (TSF)

aws.finspace.timeseries.spark.analytics.time_series_forecast_indicator(tenor, scale, time_col_name, time_axis_col_name, price_col_name)

The Time Series Forecast (TSF) indicator displays the statistical trend of a security's price over a specified time period. The trend is based on linear regression analysis. Rather than plotting a straight linear regression trend line, the Time Series Forecast plots the last point of multiple linear regression trend lines. The difference between the TSF and the moving linear regression is that the TSF adds the slope of the linear regression to the linear regression essentially projecting the position of the linear regression forward one period.

%R

aws.finspace.timeseries.spark.analytics.will_r_indicator(tenor, time_col_name, price_col_name, high_col_name, low_col_name)

Compute william %R indicator. The %R indicator was developed by Larry Williams and introduced in his 1979 book How I Made $1,000,000 Trading Commodities Last Year. Williams %R is similar to a stochastic oscillator, as it normalizes price as a percentage between 0 and 100. It is basically an inverted version of the Raw %K value of a Fast Stochastic.
