Kaufman Adaptive Moving Average

The Kaufman Adaptive Moving Average was created, not surprisingly, by Perry Kaufman. The KAMA takes into consideration the noise of the market. This version of KAMA uses smoothing constants of 2 and 30 for the periods of the shortest and longest moving averages respectively. The user may change the input (close), period length and shift number. This indicator’s definition is further expressed in the condensed code given in the calculation below.

How To Trade Using the Kaufman Adaptive Moving Average

The Kaufman Adaptive Moving Average is a lagging trend indicator and may be used in conjunction with other studies. No trading signals are calculated.

Calculation

//input = price, user defined, default is close //period = user defined, default is 20 //shift = user defined, default is 0 //kama = kaufman adaptive moving average //index = current bar number

kama = kama(index+shift,period,input);

Keltner Channel

The Keltner Channel is named after Chester W. Keltner. In this modern version of the Keltner Channel, the middle line is an exponential moving average (EMA) of the given input. The upper and lower bands are a set distance that is a multiple (range attribute) of the Average True Range from the middle line. The user may change the input (close), period lengths and range attributes. This indicator’s definition is further expressed in the condensed code given in the calculation below.

//input = price, user defined, default is close //middlePeriod= user defined, default is 20 //atrPeriod= user defined, default is 10 //upperRange = user defined, default is 2 //lowerRange = user defined, default is 2 //ma = moving average, EMA = exponential moving average //index = current bar number, atr = average true range

atr = atr(index, atrPeriod);
Plot2: ma = ma("EMA", index, middlePeriod, input);
Plot1: ma + (upperRange * atr);
Plot3: ma - (upperRange * atr);

Kirshenbaum Bands

The Kirshenbaum Bands were authored by Paul Kirshenbaum. Their range is based on standard error as calculated from a hypothetical linear regression line. This range is added to and subtracted from an exponential moving average of the price to produce a top and a bottom band. The user may change the input (close), method (EMA) and period lengths. This indicator’s definition is further expressed in the condensed code given in the calculation below.

How To Trade Using Kirshenbaum Bands

The Kirshenbaum Bands may be used in conjunction with other studies. No trading signals are calculated for this indicator.

Calculation

//input = price, user defined, default is closing price //method = moving average (ma), user defined, default is EMA //period1 = user defined, default is 30 //period2 = user defined, default is 20 //noSdDev = number of standard deviations, user defined, default is 1

//stdErr = standard error, index = current bar number

ma = ma(method, index, period1, input);
sdErr = stdErr(period2, index, input);
topBand = ma + (sdErr * noSdDev);
bottBand = ma - (sdErr * noSdDev);

Klinger Volume Oscillator

The Klinger Volume Oscillator was developed by Stephen J. Klinger. It is a conformation indicator. It uses high, low, close and volume to create a volume force. This volume force (VF) is then turned into an oscillator by taking a fast EMA of VF and subtracting a slow EMA of VF. A signal line (KOS), which is an EMA of the Klinger Oscillator (KO), is plotted to trigger trading signals. The user may change the method (EMA), and period lengths. This indicator’s definition is further expressed in the condensed code given in the calculation below.

How To Trade Using Klinger Volume Oscillator

Although signals are generated as shown in the calculation, the Klinger Volume Oscillator is considered a conformation indicator and should be used in conjunction with other indicators.

Calculation

//method = moving average (ma) user defined, default is EMA //fastPeriod = user defined, default is 34 //slowPeriod = user defined, default is 55 //signalPeriod = user defined, default is 13 //index = current bar number

lastCm = CM[index-1];
lastHigh = high[index-1];
lastLow = low[index-1];
lastClose = close[index-1];
lastDm = lastHigh - lastLow;
lastTrend = TREND[index-1];
if (lastTrend == null) lastTrend = -1;
if ((high + low + close) moreThan (lastHigh + lastLow + lastClose)) TREND = 1;
else TREND = -1;
dm = high - low;
if (TREND == lastTrend) CM = lastCm + dm;
else CM = lastDm + dm;
if (CM == 0) temp = -2;
else temp = abs(2 * (dm/CM -1));
VF = volume * temp * TREND * 100;
koFast = ma(method, index, fastPeriod, VF);
koSlow = ma(method, index, slowPeriod, VF);
Plot1: KO = koFast - koSlow;
Plot2: KOS = ma(method, index, signalPeriod, KO);
//Signals
buy = crossedAbove(KO,KOS);
sell = crossedBelow(KO, KOS);

Know Sure Thing

Know Sure Thing was developed by Martin J. Pring in the 1990s. The KST uses four rate of change values to determine the trend of the market. The user may change the input (close), methods (SMA, EMA) and multiple period lengths. This indicator’s definition is further expressed in the condensed code given in the calculation below.

How To Trade Using Know Sure Thing

LBR Paint Bars

LBR Paint Bars changes the color of the price bars depending on the trend direction. The trend is determined by the position of 2 volatility lines. The calculation of these lines uses a moving average of the Average True Range and applies it to (plus or minus) the highest highs and the lowest lows. The And Or option refers to the specific logic used see the code for details. The user may change the input (close), method (SMA), factor, period lengths and the and or option. This indicator’s definition is further expressed in the condensed code given in the calculation below.

Linear Regression

Linear Regression is a statistical representation of the price data. It is a straight line on an x (date) y (price) graph that best represents the price data between its starting and ending points. It is calculated using the sum of least squares method. The user may change the input (close), number of regression bars and number of future bars. This indicator’s definition is further expressed in the condensed code given in the calculation below.

How To Trade Using Linear Regression

The linear regression line may be used to show the current trend. The slope of the line designates an upward or downward trend. No signals are generated and it should be used in conjunction with other indicators.

Calculation

//input = price, user defined, default is closing price //noBars = user defined, default is 40 //noFutureBars = user defined, default is 1 //index = current bar number

endIndex = size() -1;
startIndex = endIndex - noBars;
value[] = linRegLine(endIndex, noBars, input);
a = value[0];   //a in line equasion y = a + (m * x)
m = value[1];  //m in line equasion y = a + (m * x)
//y = a + (m * x)
startY = a + (m * 0);
endY = a + (m * noBars);
start = Coordinate(getStartTime(startIndex), startY);
end = Coordinate(getStartTime(endIndex), endY);
line = Line(start, end);
line.setExtendRight(noFutureBars);
addFigure(line);

Linear Regression Curve

Linear Regression Curve (LRC) is a type of Moving Average based on the linear regression line equation (y = a + mx). The calculation produces a straight line with the best fit for the various prices for the period. The endpoint of this line is used to plot the LRC. A signal line (PRICE), which is the price chosen by the user is used to help trigger signals. Two user factors are applied to the price to determine the buy or sell signal. The user may change the input (close), period length and factors. This indicator’s definition is further expressed in the condensed code given in the calculation below.

How To Trade Using Linear Regression Curve

A buy signal is generated when the price moves below the linear regression curve times a user-defined percent value. Conversely, a sell signal is given when the price moves above the linear regression curve times a user-defined percent value.

Calculation

//input = price, default is closing price //period = linear regression period, default is 9 //pcAbove = percent above, default is .009 //pcBelow = percent below, default is .009 //index = current bar number

price = getPrice(index, input, 0);
linReg = linRegLine(index, period, input, period)[0]; //end point of lin. reg. line
plot1: linReg;
plot2: price;
//Signals
pcAbove = 1 + pcAbove/100.0;
pcBelow = 1 - pcBelow/100.0;
sell = price moreThan; linReg * pcAbove;
buy = price lessThan; linReg * pcBelow;

Linear Regression Channel

Linear Regression Channel is a popular technical analysis that uses price volatility to provide the price trend directions and the potential buy/sell signals. This indicator displays a channel using a standard deviation multiplier above or below a Linear Regression trend line. The Linear Regression trend line is the middle/center line that represents the general trend in price movements. The other two lines: The Upper and Lower Channel, are paralleled to the center line, and their distances are computed using Standard Deviations. These Upper and Lower Channel lines act as resistance and support to signal potential breakouts of the price trend, therefore, offering buy or sell opportunities.

How to trade using Linear Regression Channel

The slopes of the channel indicate the trend of the prices, whether they are in an upward or downward trend, or a sideways market (flat slope).

By default, markers are generated when the prices cross above or below the top (Upper Channel line) or the bottom (Lower Channel line) lines. Users can enable/disable the markers for clearer readings.

In general, sell signals are given when the price reaches the resistance level (Upper Channel line). The sell signals are more reliable when the channel is in a downtrend. Conversely, buy signals are shown when the price drops right below the support level (Lower Channel line). The buy signals are more reliable when the channel is in an uptrend.

Linear Regression Slope

Linear Regression Slope is part of Standard Error Bands by Jon Anderson, Stocks and Commodities Mag. 09/1996. This study should be used with Standard Error PercentA, R Squared and Bollinger Bands®. The user may change the input (close) and period length. This indicator’s definition is further expressed in the condensed code given in the calculation below.

How To Trade Using Linear Regression Slope

Linear Regression Slope should be used with Standard Error PercentA, R squared and Bollinger Bands®. For a buy opportunity look for narrow Bollinger Bands® turning upward, R squared in the top 15 percent, and the upward trend of the Standard Error PercentA and the Linear Regression Slope. For a sell opportunity look for narrow Bollinger Bands® turning downward, R squared in the bottom 15 percent, and the downward trend of the Standard Error PercentA and Linear Regression Slope. No trading signals are calculated by this study.

Calculation

//input = price, user defined, default is close //period = user defined, default is 21 //index = current bar number

lrs = linRegLine(index, period, input, 0)[1];  //returns linear regression slope
Plot: lrs
