Minutes Before Session Close (MinutesBeforeSessionClose)

The minutes before session close shows the number of minutes before the session closed that the selected tick occurred.

Example: MinutesBeforeSessionClose(@)

This function has no parameters.

Modulus

Modulus returns the remainder after division.

In mathematics, the remainder is the amount "left over" after division. For example, the remainder of 10 / 4 is 2, because 4 goes into ten twice with two left over. You'll see this written as 10 / 4 = 2 r 2, the 'r' standing for remainder.

Format: Modulus(@,@)

For example:

Modulus(10,4)

10 / 4 = 2 with a remainder of 2

Modulus returns 2

This function has no parameters.

Native Currency to Price (D2P)

Native Currency to Price converts US Dollars to price units. There are two forms:

Dollar2Price(X) converts X to price units using the currents contract for the price scale.

For example: Low(@) –Dollar2Price(2000) returns a price line equivalent to $2000 under the low of the bar or 2000 ticks.

Dollar2Price(y,x) converts X to price units, using y for the price scale.

For example: Low(@)-Dollar2Price(SP,2000) will return a price line $2000 under the low using SP price scale. This would translate into 800 ticks under the low.

Example: DollarToPrice(@)

This function has no parameters.

Natural Log (Log)

Displays the natural log of chart values.

Example: Natlog(@)

Style = Choose a line style: line, long dash, or short dash.

Net Change (NC)

Net change is the difference between today’s current price and the settlement price.

Example: NC(@)

This function has no parameters.

Peak (Peak)

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.

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)

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(@)

Sample (Samp)

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.

Example:

Seconds Since Bar Opened (SecSinceBarOp)

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

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.

Use Edges	SetRst(Hour(@)=9,Hour(@)=12) with Use Edges will not trip to 1 on a 5min 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.

Example: ShrScale(@,@)

Parameter	Description

Standard Deviation (StdDev)

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

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).
