AdaptiveMovingAverage

Alias:

• KAMA, MovingAverageAdaptive

Defined by Perry Kaufman in his book “Smarter Trading”.

It is A Moving Average with a continuously scaled smoothing factor by taking into account market direction and volatility. The smoothing factor is calculated from 2 ExponetialMovingAverage smoothing factors, a fast one and slow one.

If the market trends the value will tend to the fast ema smoothing period. If the market doesn’t trend it will move towards the slow EMA smoothing period.

It is a subclass of SmoothingMovingAverage, overriding once to account for the live nature of the smoothing factor

Formula:

• direction = close - close_period

• volatility = sumN(abs(close - close_n), period)

• effiency_ratio = abs(direction / volatility)

• fast = 2 / (fast_period + 1)

• slow = 2 / (slow_period + 1)

• smfactor = squared(efficienty_ratio * (fast - slow) + slow)

• smfactor1 = 1.0 - smfactor

• The initial seed value is a SimpleMovingAverage

AroonDown

This is the AroonDown from the indicator AroonUpDown developed by Tushar Chande in 1995.

Formula:

• down = 100 * (period - distance to lowest low) / period

Note:

The lines oscillate between 0 and 100. That means that the “distance” to the last highest or lowest must go from 0 to period so that the formula can yield 0 and 100.

Hence the lookback period is period + 1, because the current bar is also taken into account. And therefore this indicator needs an effective lookback period of period + 1.

DemarkPivotPoint

Defines a level of significance by taking into account the average of price bar components of the past period of a larger timeframe. For example when operating with days, the values are taking from the already “past” month fixed prices.

Example of using this indicator:

data = btfeeds.ADataFeed(dataname=x, timeframe=bt.TimeFrame.Days) cerebro.adddata(data) cerebro.resampledata(data, timeframe=bt.TimeFrame.Months)

In the __init__ method of the strategy:

pivotindicator = btind.DemarkPivotPoiont(self.data1) # the resampled data

The indicator will try to automatically plo to the non-resampled data. To disable this behavior use the following during construction:

• _autoplot=False

Note:

The example shows days and months, but any combination of timeframes can be used. See the literature for recommended combinations

Formula:

• if close < open x = high + (2 x low) + close

• if close > open x = (2 x high) + low + close

• if Close == open x = high + low + (2 x close)

• p = x / 4

• support1 = x / 2 - high

DicksonMovingAverage

Alias:

• DMA, DicksonMA

By Nathan Dickson

The Dickson Moving Average combines the ZeroLagIndicator (aka ErrorCorrecting or EC) by Ehlers, and the HullMovingAverage to try to deliver a result close to that of the Jurik Moving Averages

Formula:

• ec = ZeroLagIndicator(period, gainlimit)

• hma = HullMovingAverage(hperiod)

• dma = (ec + hma) / 2

• The default moving average for the ZeroLagIndicator is EMA, but can be changed with the parameter _movav

  备注

  the passed moving average must calculate alpha (and 1 - alpha) and make them available as attributes alpha and alpha1

• The 2nd moving averag can be changed from Hull to anything else with the param _hma

FibonacciPivotPoint

Defines a level of significance by taking into account the average of price bar components of the past period of a larger timeframe. For example when operating with days, the values are taking from the already “past” month fixed prices.

Fibonacci levels (configurable) are used to define the support/resistance levels

Example of using this indicator:

data = btfeeds.ADataFeed(dataname=x, timeframe=bt.TimeFrame.Days) cerebro.adddata(data) cerebro.resampledata(data, timeframe=bt.TimeFrame.Months)

In the __init__ method of the strategy:

pivotindicator = btind.FibonacciPivotPoiont(self.data1) # the resampled data

The indicator will try to automatically plo to the non-resampled data. To disable this behavior use the following during construction:

• _autoplot=False

Note:

The example shows days and months, but any combination of timeframes can be used. See the literature for recommended combinations

Formula:

• pivot = (h + l + c) / 3 # variants duplicate close or add open

HullMovingAverage

Alias:

• HMA, HullMA

By Alan Hull

The Hull Moving Average solves the age old dilemma of making a moving average more responsive to current price activity whilst maintaining curve smoothness. In fact the HMA almost eliminates lag altogether and manages to improve smoothing at the same time.

Formula:

• hma = wma(2 * wma(data, period // 2) - wma(data, period), sqrt(period))

See also:

• http://alanhull.com/hull-moving-average

Note:

• Please note that the final minimum period is not the period passed with the parameter period. A final moving average on moving average is done in which the period is the square root of the original.

  In the default case of 30 the final minimum period before the moving average produces a non-NAN value is 34

Interpretation of the results

1. Geometric random walk (H=0.5)

2. Mean-reverting series (H<0.5)

3. Trending Series (H>0.5)

Important notes:

• The default period is 40, but experimentation by users has shown that it would be advisable to have at least 2000 samples (i.e.: a period of at least 2000) to have stable values.

• The lag_start and lag_end values will default to be 2 and self.p.period / 2 unless the parameters are specified.

  Experimentation by users has also shown that values of around 10 and 500 produce good results

The original values (40, 2, self.p.period / 2) are kept for backwards compatibility

PivotPoint

Defines a level of significance by taking into account the average of price bar components of the past period of a larger timeframe. For example when operating with days, the values are taking from the already “past” month fixed prices.

Example of using this indicator:

data = btfeeds.ADataFeed(dataname=x, timeframe=bt.TimeFrame.Days) cerebro.adddata(data) cerebro.resampledata(data, timeframe=bt.TimeFrame.Months)

In the __init__ method of the strategy:

pivotindicator = btind.PivotPoiont(self.data1) # the resampled data

The indicator will try to automatically plo to the non-resampled data. To disable this behavior use the following during construction:

• _autoplot=False

Note:

The example shows days and months, but any combination of timeframes can be used. See the literature for recommended combinations

Formula:

• pivot = (h + l + c) / 3 # variants duplicate close or add open

• support1 = 2.0 * pivot - high

• support2 = pivot - (high - low)

• resistance1 = 2.0 * pivot - low

• resistance2 = pivot + (high - low)

PrettyGoodOscillator

Alias:

• PGO, PrettyGoodOsc

The “Pretty Good Oscillator” (PGO) by Mark Johnson measures the distance of the current close from its simple moving average of period Average), expressed in terms of an average true range (see Average True Range) over a similar period.

So for instance a PGO value of +2.5 would mean the current close is 2.5 average days’ range above the SMA.

Johnson’s approach was to use it as a breakout system for longer term trades. If the PGO rises above 3.0 then go long, or below -3.0 then go short, and in both cases exit on returning to zero (which is a close back at the SMA).

Formula:

• pgo = (data.close - sma(data, period)) / atr(data, period)

RelativeMomentumIndex

Alias:

• RMI

Description: The Relative Momentum Index was developed by Roger Altman and was introduced in his article in the February, 1993 issue of Technical Analysis of Stocks & Commodities magazine.

While your typical RSI counts up and down days from close to close, the Relative Momentum Index counts up and down days from the close relative to a close x number of days ago. The result is an RSI that is a bit smoother.

Usage: Use in the same way you would any other RSI . There are overbought and oversold zones, and can also be used for divergence and trend analysis.

RelativeStrengthIndex

Alias:

• RSI, RSI_SMMA, RSI_Wilder

Defined by J. Welles Wilder, Jr. in 1978 in his book “New Concepts in Technical Trading Systems”.

It measures momentum by calculating the ration of higher closes and lower closes after having been smoothed by an average, normalizing the result between 0 and 100

Formula:

• up = upday(data)

• down = downday(data)

• maup = movingaverage(up, period)

• madown = movingaverage(down, period)

• rs = maup / madown

• rsi = 100 - 100 / (1 + rs)

The moving average used is the one originally defined by Wilder, the SmoothedMovingAverage

See:

• http://en.wikipedia.org/wiki/Relative_strength_index

Notes:

• safediv (default: False) If this parameter is True the division rs = maup / madown will be checked for the special cases in which a 0 / 0 or x / 0 division will happen

• safehigh (default: 100.0) will be used as RSI value for the x / 0 case

StochasticFast

By Dr. George Lane in the 50s. It compares a closing price to the price range and tries to show convergence if the closing prices are close to the extremes

• It will go up if closing prices are close to the highs

• It will roughly go down if closing prices are close to the lows

It shows divergence if the extremes keep on growing but closing prices do not in the same manner (distance to the extremes grow)

Formula:

• hh = highest(data.high, period)

• ll = lowest(data.low, period)

• knum = data.close - ll

• kden = hh - ll

• k = 100 * (knum / kden)

WilliamsAD

By Larry Williams. It does cumulatively measure if the price is accumulating (upwards) or distributing (downwards) by using the concept of UpDays and DownDays.

Prices can go upwards but do so in a fashion that no longer shows accumulation because updays and downdays are canceling out each other, creating a divergence.

ZeroLagExponentialMovingAverage

Alias:

• ZLEMA, ZeroLagEma

The zero-lag exponential moving average (ZLEMA) is a variation of the EMA which adds a momentum term aiming to reduce lag in the average so as to track current prices more closely.

Formula:

• lag = (period - 1) / 2

• zlema = ema(2 * data - data(-lag))

ZeroLagIndicator

Alias:

• ZLIndicator, ZLInd, EC, ErrorCorrecting

By John Ehlers and Ric Way

The zero-lag indicator (ZLIndicator) is a variation of the EMA which modifies the EMA by trying to minimize the error (distance price - error correction) and thus reduce the lag

Formula:

• EMA(data, period)

• For each iteration calculate a best-error-correction of the ema (see the paper and/or the code) iterating over -bestgain -> +bestgain for the error correction factor (both incl.)

• The default moving average is EMA, but can be changed with the parameter _movav

  备注

  the passed moving average must calculate alpha (and 1 - alpha) and make them available as attributes alpha and alpha1 in the instance

haDelta

Alias:

• haD

Heikin Ashi Delta. Defined by Dan Valcu in his book “Heikin-Ashi: How to Trade Without Candlestick Patterns “.

This indicator measures difference between Heikin Ashi close and open of Heikin Ashi candles, the body of the candle.

To get signals add haDelta smoothed by 3 period moving average.

For correct use, the data for the indicator must have been previously passed by the Heikin Ahsi filter.

Formula:

• haDelta = Heikin Ashi close - Heikin Ashi open

• smoothed = movav(haDelta, period)
