#### Peak (Peak)

This function is available on the Add Study window and in the Formula Toolbox.

The Hi/Lo Peak study identifies important highs and lows based on the number of bars, both to the left and to the right (before and after), which have lower highs to identify a Hi Peak or higher lows to identify a Lo Peak. Hi/Lo Peak identifies extreme price points of the same magnitude, based on the surrounding price action.

Characteristics & Usage

Hi/Lo Peak provides a method to consistently identify extreme price points of the same magnitude.

Hi/Lo Peak is an effective tool to identify important support and resistance levels based on recent price extremes.

The Hi/Lo Peak lines may be used to define a trading range.

The Lo Peak line identifies the price that attracted a bid and the Hi Peak line identifies the price level that attracted an offer.

A break above or below a Peak line may be considered a breakout of the trading range.

Hi/Lo Peak may also be used in a trend following manner.

A bull trend is indicated when price action persists above the Hi Peak.

An upward adjustment of the Hi Peak indicates the trend has terminated (this is due to the fact that Hi Peak will only adjust upward once lower highs follow an extreme high, indicating the bulls have been unable to bid prices beyond the highs for several bars).

The opposite holds for using Lo Peak to identify a bear trend and its termination.

When the Min/Max parameter is On, Hi/Lo Peak may be used to track the maximum and minimum values dependent on the Reset parameters. Reset parameters are employed so that Hi/Lo Peak will continue to be a responsive indicator, rather than simply identifying the highest and lowest points on a chart.

Calculation

Hi Peak = Highest Price with LLev (number) of lower highs preceding the Hi Peak and RLev (number) of lower highs following it.

Lo Peak = Lowest Price with LLev (number) of higher lows preceding the Lo Peak and RLev (number) of higher lows following it.

For variations see Parameters for Peak.

Example: HiPeak(@,1,1), LoPeak(@,1,1)

Example: HiCount(@,1,1), Lo Count(@,1,1)

 Parameter Description Display Opens a sub-window with display properties: Color = Select a line color. Weight = Type a value for line thickness. Display = Select line style: line, histogram, or dash. ShareScale = Assign a behavior for functions and studies sharing the vertical scale: Auto = System determine whether sharing is feasible. On = Scale is shared regardless of the functions and studies displayed. Off = Scale is not shared. Price Reference price. Optional settings include: Open, High, Low, Close, Mid-pt, HLC/3, Average, True High, True Low, Range, True Range, or Peak may reference Conditions. LLev Determines the number of bars to the left of the Hi/Lo peak which must have a lower Hi/higher Lo. RLev Determines the number of bars to the right of the Hi/Lo peak which must have a lower Hi/higher Lo. Offset Determines the number of bars to offset the PEAK Hi/Lo lines. Resets Opens a sub-window where you set Max/Min levels. Min/Max values: Hi Off = PEAK lines will move up or down in accordance with the parameters set above. Hi On = PEAK will track the Price higher, identifying each higher PEAK. Hi PEAK maintains its maximum value until the Reset parameters force PEAK to accept a lower value, in accordance with the parameters below. Price falls below the Threshold and crosses back above the Threshold value at which point Hi PEAK will reset to the Threshold level. Lo On = PEAK will track the Price lower identifying each lower PEAK. Lo PEAK will maintain its minimum value until the Reset parameters force PEAK to accept a higher value, in accordance with the parameters below. Price rises above the Threshold and crosses back below the Threshold value at which point Lo PEAK will reset to the Threshold level. Reset vales: <= or />= The Threshold level will serve as a Minimum/Maximum value which PEAK will take. Above this level Hi PEAK will identify extreme Prices as specified above, while Lo PEAK will identify extreme Prices below the Threshold level. XA/XB = When the selected Price crosses above/below the Threshold PEAK will revert to the Threshold value and once again begin to track extreme Price values. Trig = Activates the Reset Trigger as a method to force Hi PEAK to accept a lower value and Lo PEAK to accept a higher value. Reset Trigger = Condition that serves as the Trigger for PEAK to assume the value of Price when the condition is true. The Reset Trig forces Hi PEAK to accept a lower value than the maximum while forcing the Lo PEAK to accept higher values. Threshold = Threshold serves as a minimum value for Hi PEAK and a maximum value for Lo PEAK when either <=/>= is selected or when XA/XB is selected and Price has broken the Threshold. Once Hi/Lo PEAK crosses below/above the Threshold, PEAK will no longer respond to price action, until Price remains beyond the threshold for the total number of bars of LLev and RLev summed together (i.e. using the defaults, the price must remain beyond the Threshold for 3 days to be detected).

#### Power (Pwr)

For example: Price2Dollar(High(@)-Low(@)) returns the range of the bar in dollars.

Price2Dollar(y,x) converts X to dollars using a specific price scale (Y) different than the one on the chart.

For example: Price2Dollar(SP,High(@)-Low(@)) if applied to a NASDAQ (ND) chart, will return the price of the trading range of the NASDAQ futures bar using the SP price scale.

Example: PriceToDollar(@)

 Parameter Description Price Price used for calculation.

#### Round (Round)

This function is available on the Add Study window and in the Formula Toolbox.

#### Sample (Samp)

This function is available on the Add Study window and in the Formula Toolbox.

Sample identifies the price at which a condition is met. This study evaluates a condition on a True/False basis and returns the desired input value (price) when the condition changes from False to True or remains True, depending on parameter settings.

Sample is an effective tool for identifying support and resistance points defined by the occurrence of a specific condition.

An example is to use High as the input on a downside reversal day. The Sample parameters would be set as following:

Price = High

Capture = At Edge (when condition changes from false to true)

Hold = On (continue calculating until condition changes from false to true again)

Condition = Higher High than prior bar and a close down.

Sample may be used to assist in the development of a trade system, since it enables the user to identify specific events and analyze the market behavior following such an event.

Sample is similar to an If function. Both functions return a Price or User value when a defined condition occurs.

Sample provides the user with greater flexibility to select or hold a specific value, based on the selected parameter settings.

The Seconds Since Bar Opened function shows the number of minutes, seconds, and milliseconds after the bar opened that the selected tick occurred. Millisecond precision applies to all bars and not only the current bar.

Note that the time increment is taken from chart preferences|topic=Time Scale.

Example: SecSinceBarOp(@)

This function has no parameters.

#### Set/Reset (SetRst)

This function is available on the Add Study window and in the Formula Toolbox.

Set/Reset creates a picture of binary data for you, using two conditions. The first condition is displayed as an uptick on a line graph. The line continues on that level until the second condition is satisfied. Then the line returns to its baseline until the first condition occurs again. On a bar graph, the bars change colors to reflect the set and reset conditions.

For example:

mval := MACD(@,13,26);

diff := mval - MACDA(@,13,26,9);

SetReset(mval XABOVE 0, diff < diff[-1])

In this example on a bar graph, this formula would color bars when MACD crossed above zero and would stop marking the bars when the difference between the MACD and the MACDA turned down.

Example: SetRst(Hour(@)=9,Hour(@)=12)

 Parameter Description Display Opens a sub-window with display properties: Color = Select a line color. Weight = Type a value for line thickness. Display = Select line style: line, histogram, or dash. ShareScale = Assign a behavior for functions and studies sharing the vertical scale: Auto = System determine whether sharing is feasible.

Use Edges SetRst(Hour(@)=9,Hour(@)=12) with Use Edges will not trip to 1 on a 5min bar chart until the first bar on which it turns is complete the 9:00 bar. It actually returns 1 or true on the bar immediately following the first condition 9:05, hence the term “use edges.” Rather than show true at start of the start condition bar, it waits until the starting condition - start bar is completed. Without Use Edges, it will immediately turn to true when the start condition (Hour(@)=9) bar is first formed.

#### ShareScale (ShrScl)

This function is available on the Add Study window and in the Formula Toolbox.

ShareScale forces a bar value or formula (expression 1) to use the same scale as a bar chart or other value (expression2).

There are two forms for this function:

ShareScale(expr1): In this form, ShareScale forces expr1 to be displayed using the same units as the chart. For example: ShareScale(Low(@)-10*TickSize(@)) will ensure the same scale is used for the line that is generated as the bar chart on which it is overlaid.

ShareScale(expr1, expr2): This forces expr1 to be displayed using the same scaling as expr2.

Standard Deviation is a statistical measure indicating the variability of the data points. High standard deviations are believed by some analysts to indicate market tops, while the opposite is true for lower Standard Deviations. Calculating the Standard Deviation involves taking the square root of the deviations from a simple moving average.

The following formula describes the Standard Deviation ( ): Sum the square of the difference of each PRICE (x) for the PERIOD (n), and the Simple Moving Average value (m).

Divide the sum by the PERIOD (n).

Display = Select line style: line, histogram, or dash. ShareScale = Assign a behavior for functions and studies sharing the vertical scale: Auto = System determine whether sharing is feasible. On = Scale is shared regardless of the functions and studies displayed. Off = Scale is not shared. MarkIt Opens the Specify Conditions for Marking Bar window. Period Time period for the moving average calculations. Price Price used for calculations. OB/OS Opens a sub-window with properties for overbought and oversold indicators. Color = Select a line color. Weight = Type a value for line thickness. Type = Select fixed or dynamic. Std Dev = Choose a multiplier of the Standard Deviation used to derive high and low. Lookback = Choose the number of bars that should be compared to the current bar. Level = Assign a percentage value of average OB/OS to be used to calculate predictor OB/OS levels. Display = Click this check box to display the line on the chart. Style = Choose a line style: line, long dash, or short dash.

#### Tan (Tan)

This function is available on the Add Study window and in the Formula Toolbox.

The Tan function takes the selected chart value, converts it into radians, and calculates a tangent value. For example, the tangent value of 1090 would be .13. This value is calculated as follows:

1090/(2*pi) = 173.478 Calculates the laps around the unit circle

.478 * (2*pi) = 3.00894 Takes the leftover lap and converts it to radians

Sin( 3.00894) radians = .13226249 Calculates the sine for the calculated radians

.13226249/.99124775 = .1334 Divides the sine by the cosine

Example: Tan(@)

 Parameter Description Display Opens a sub-window with display properties: Color = Select a line color. Weight = Type a value for line thickness. Display = Select line style: line, histogram, or dash. ShareScale = Assign a behavior for functions and studies sharing the vertical scale: Auto = System determine whether sharing is feasible. On = Scale is shared regardless of the functions and studies displayed. Off = Scale is not shared. MarkIt Opens the Specify Conditions for Marking Bar window. Price Price used for calculations.

#### Tick Size (TSize)

This function is available on the Add Study window and in the Formula Toolbox.

TickSize returns the size of the minimum price units.

For example, High(@) +10*TickSize(@) returns a line ten ticks above the high of each bar.

TickSize can be used to create a channel line above and/or below a bar or candlestick chart. TickSize can also be used to define a specific price level in conditions, user formulas or trade systems.

Example: High(@) +10*TickSize(@)
 Parameter Description Display Opens a sub-window with display properties: Color = Select a line color. Weight = Type a value for line thickness. Display = Select line style: line, histogram, or dash. ShareScale = Assign a behavior for functions and studies sharing the vertical scale: Auto = System determine whether sharing is feasible. On = Scale is shared regardless of the functions and studies displayed. Off = Scale is not shared. MarkIt Opens the Specify Conditions for Marking Bar window.

#### Time (Time)

This function is available on the Add Study window and in the Formula Toolbox.

The Time function plots the value of a point in time, allowing users to include these values in user formulas. The function plots the following:

Year

Month: 1 for January, 2 for February, 3 for March, etc.

Day

Hour

Minute

Day of Week

Week

Day of Year

Local versions, e.g. Local Year and Local Day of Week, are available in the Formula Toolbox.

DayofWeek(@) returns 1 for Monday, 2 for Tuesday, 3 for Wednesday, 4 for Thursday, 5 for Friday, 6 for Saturday, and 7 for Sunday.

It uses the start time of the bar for its calculation.

For example, for Monday's daily bar it returns 7 (Sunday) because the bar actually starts at Sunday 15:30.

LocalDayofWeek(@) returns 1 for Monday, 2 for Tuesday, 3 for Wednesday, 4 for Thursday, 5 for Friday, 6 for Saturday, and 7 for Sunday.

It uses the time from the chart’s horizontal scale for its calculation and is sensitive to Time preferences.

For a daily bar it returns the day of the week for that day.

DOW(@) returns 1 for Sunday, 2 for Monday, 3 for Tuesday, 4 for Wednesday, 5 for Thursday, 6 for Friday, and 7 for Saturday.

For intraday, it uses the start time of the bar for its calculation, the same as Day of Week (DayofWeek).

For daily and above, it uses the trading date for its calculation. For example, for Monday's daily bar it returns 2 (Monday).
 Parameter Description Display Opens a sub-window with display options for year, month, day, hour, minute, day of the week, week, and day of the year. Color: Select a color for the line. Weight: Choose how thick you want the study line. ShareScale Determines whether sharing of the vertical scales between studies is accepted. Digits Number of digits displayed after the decimal point. Use Local Time Overrides any other time setting, so that local time is used.

#### Time Average (TimAvg)

This function is available on the Add Study window and in the Formula Toolbox.

Calculates the average for values taken at the same time of day (typically BarIX).

Example: TimAvg(@,@,10)
 Parameter Description Display Opens a sub-window with display properties: Color = Select a line color. Weight = Type a value for line thickness. Display = Select line style: line, histogram, or dash. ShareScale = Assign a behavior for functions and studies sharing the vertical scale: Auto = System determine whether sharing is feasible. On = Scale is shared regardless of the functions and studies displayed. Off = Scale is not shared. MarkIt Opens the Specify Conditions for Marking Bar window. Price Price used for calculation. Checkup Choices include: Close, Open, High Low, Mid, HLC3, Average, TrueHigh, TrueLow,Range, TrueRange, TickVol, Vol, CurrentOpen, CurrentHigh, CurrentLow, Last, CurrentVol, CurrentTickVol, BestBid, BestBidVol, BestAsk, BestAskVol. Period The time period for the moving average calculations. Extra Steps A look back maximum period that the formula will try to compute. If you were to create, for example, a 1001 period variable, but the steps only went back 1000 the calculation wouldn’t work.

#### Time Compare (TCmp)

This function is available on the Add Study window and in the Formula Toolbox.

The Time Compare function compares a user-selected time (for intraday bars) or date (for daily or longer bars) to the time or date where the vertical cursor is positioned. The study reports values for six possibilities. It returns a 1 if the choice is true and a zero if it is false. The six possibilities are:

Time EQ: The time represented by the vertical cursor position is the same as the user-selected time.

Time NE: The time represented by the vertical cursor position is not the same as the user-selected time.

Time GT: The time represented by the vertical cursor position is later than the user-selected time.

Time GE: The time represented by the vertical cursor position is later or the same as the user-selected time.

Time LT: The time represented by the vertical cursor position is earlier than the user-selected time.

Time LE: The time represented by the vertical cursor position is earlier or the same as the user-selected time.
 Parameter Description Display Opens a sub-window with display properties: Color = Select a line color. Weight = Type a value for line thickness. Display = Select line style: line, histogram, or dash. Date Selects the date for the comparison for daily or longer bars. Time Selects the time for the comparison for bars shorter than daily.

#### Truncate Display (TrncDsp)

This function can be accessed only in the Toolbox.

This formula restricts the display of a study by n bars. It works backward from the most recent bar.

For example, TrncDsp(MA(@,Sim,21),10) would display only the last 10 values of a 21-period moving average. The average is still calculated using 21 periods; only the display is affected.

Example: TrncDsp(MA(@,Sim,21),10)

 Parameter Description Trailing Bars Select the number of bars to display.

#### Yield Value (Yield)

This function can be accessed only in the Toolbox.

It calculates the yield value for a contract, provided that contract has yield specified.

You can apply this function to a contract or to a spread strategy. For example:

Yield(TYA)

Yield(SPREAD(TYA-USA, , 0.001, 1:2, , 1))

SPREAD(Yield(TYA)-YIELD(BTC10), , 0.001, 10:1, , 1)

 Parameter Description Mode Select a type: default, specific issue, or custom. Calculation Opens a sub-window with parameters for custom and specific issue modes:
