ConsoleLibrary "Console" █   OVERVIEW An easy way to output messages to a console like table using a a simple "print" function that can be called from anywhere in your code including functions. █   Supports: - Scrollable console messages - Customisable number of displayed messages - More than one "console" for different types of output if required - The ability to choose which message to start viewing from (useful if the message list is long) - The ability to place the console table at different positions on the chart to mitigate against overwriting an existing table. █   Limitations: The "scrollbar" handle is actually a modified time widget handle. As the handle is grabbed and moved left or right across the chart bars, this script calculates the offset of the bar being pointed to from the last bar in the chart and uses that as the console message offset. However, It isn't possible to position this on the last chart bar with code. So there are two solutions: 1) Manually change timestamp of the variable scrollStart to the current time (roughly) eg. scrollStart = "25 Dec 2022 14:30 +0000" 2) Use a higher timeframe (Weeks or Months) and visually find the scroll bar. If it is to the right of the chart bars the console output will read NaN. Grab the handle and move it left and it will snap to the last chart candle position. If it is to the left then find it and move it to the right as needed. █   Notes On Usage - Import the library as console (the call will be console.print(...) ) - Assign a console variable name and call the console.initialise function eg. var con1=console.initialise() - Use the console.print() function to print a message or messages This takes two parameters: _consoleName :this is the console name you are printing to _message: this is the message that you want to display. It is a string and can be built in the normal way using any pinescript string functions like str.tostring() etc - Use the console.display function to display the messages. To work as intended this display function should be placed at the last line with the following code if i_showMessages ....if i_displayTable == "con1" ........display(con1, i_lineOffset, i_rowsToDisplay, i_gotoMsg, posn) (More "consoles" can be written to and the example code provided with the library shows this in more detail. Also, the indents don't show in these notes) Lastly, placement of a console.print() without a qualifying "if" statement will occur for every bar. This may be desired. If not then use under an if statement (example in the supplied code). Happy debugging :) ----------------------------------------------------------------------------------------------------------- initialise()   initialise: creates the message array   Parameters:      none :   Returns: message array: this is assigned to the "console" identifier print(_consoleName, _message)   used to output the desired text string to the console   Parameters:      _consoleName : : the message array      _message : : the console message   Returns: none display(_consoleName, _lineOffset, _rowsToDisplay, _gotoMsg, _posn)   display: placed in the last section of code.

lower_tf█   OVERVIEW This library is a Pine programmer’s tool containing functions to help those who use the request.security_lower_tf() function. Its `ltf()` function helps translate user inputs into a lower timeframe string usable with request.security_lower_tf() . Another function, `ltfStats()`, accumulates statistics on processed chart bars and intrabars. █   CONCEPTS Chart bars Chart bars , as referred to in our publications, are bars that occur at the current chart timeframe, as opposed to those that occur at a timeframe that is higher or lower than that of the chart view. Intrabars Intrabars are chart bars at a lower timeframe than the chart's. Each 1H chart bar of a 24x7 market will, for example, usually contain 60 intrabars at the ​LTF of 1min, provided there was market activity during each minute of the hour. Mining information from intrabars can be useful in that it offers traders visibility on the activity inside a chart bar. Lower timeframes (LTFs) A lower timeframe is a timeframe that is smaller than the chart's timeframe. This framework exemplifies how authors can determine which ​LTF to use by examining the chart's timeframe. The ​LTF determines how many intrabars are examined for each chart bar; the lower the timeframe, the more intrabars are analyzed. Intrabar precision The precision of calculations increases with the number of intrabars analyzed for each chart bar. As there is a 100K limit to the number of intrabars that can be analyzed by a script, a trade-off occurs between the number of intrabars analyzed per chart bar and the chart bars for which calculations are possible. █   `ltf()` This function returns a timeframe string usable with request.security_lower_tf() . It calculates the returned timeframe by taking into account a user selection between eight different calculation modes and the chart's timeframe. You send it the user's selection, along with the text corresponding to the eight choices from which the user has chosen, and the function returns a corresponding ​LTF string. Because the function processes strings and doesn't require recalculation on each bar, using var to declare the variable to which its result is assigned will execute the function only once on bar zero and speed up your script: var string ltfString = ​ltf(ltfModeInput, LTF1, LTF2, LTF3, LTF4, LTF5, LTF6, LTF7, LTF8) The eight choices users can select from are of two types: the first four allow a selection from the desired amount of chart bars to be covered, the last four are choices of a fixed number of intrabars to be analyzed per chart bar. Our example code shows how to structure your input call and then make the call to `ltf()`. By changing the text associated with the `LTF1` to `LTF8` constants, you can tailor it to your preferences while preserving the functionality of `ltf()` because you will be sending those string constants as the function's arguments so it can determine the user's selection. The association between each `LTFx` constant and its calculation mode is fixed, so the order of the arguments is important when you call `ltf()`. These are the first four modes and the `LTFx` constants corresponding to each: Covering most chart bars (least precise) — LTF1 Covers all chart bars. This is accomplished by dividing the current timeframe in seconds by 4 and converting that number back to a string in timeframe.period format using secondsToTfString() . Due to the fact that, on premium subscriptions, the typical historical bar count is between 20-25k bars, dividing the timeframe by 4 ensures the highest level of intrabar precision possible while achieving complete coverage for the entire dataset with the maximum allowed 100K intrabars. Covering some chart bars (less precise) — LTF2 Covering less chart bars (more precise) — LTF3 These levels offer a stepped ​LTF in relation to the chart timeframe with slightly more, or slightly less precision. The stepped lower timeframe tiers are calculated from the chart timeframe as follows: Chart Timeframe Lower Timeframe Less Precise More Precise < 1hr 1min 1min < 1D 15min 1min < 1W ​2hr​ 30min > 1W 1D 60min Covering the least chart bars (most precise) — LTF4 Analyzes the maximum quantity of intrabars possible by using the 1min ​LTF, which also allows the least amount of chart bars to be covered. The last four modes allow the user to specify a fixed number of intrabars to analyze per chart bar. Users can choose from 12, 24, 50 or 100 intrabars, respectively corresponding to the `LTF5`, `LTF6`, `LTF7` and `LTF8` constants. The value is a target; the function will do its best to come up with a ​LTF producing the required number of intrabars. Because of considerations such as the length of a ticker's session, rounding of the ​LTF to the closest allowable timeframe, or the lowest allowable timeframe of 1min intrabars, it is often impossible for the function to find a ​​LTF producing the exact number of intrabars. Requesting 100 intrabars on a 60min chart, for example, can only produce 60 1min intrabars. Higher chart timeframes, tickers with high liquidity or 24x7 markets will produce optimal results. █   `ltfStats()` `ltfStats()` returns statistics that will be useful to programmers using intrabar inspection. By analyzing the arrays returned by request.security_lower_tf() in can determine:  • intrabarsInChartBar : The number of intrabars analyzed for each chart bar.  • chartBarsCovered : The number of chart bars where intrabar information is available.  • avgIntrabars : The average number of intrabars analyzed per chart bar. Events like holidays, market activity, or reduced hours sessions can cause the number of intrabars to vary, bar to bar. The function must be called on each bar to produce reliable results. █   DEMONSTRATION CODE Our example code shows how to provide users with an input from which they can select a ​LTF calculation mode. If you use this library's functions, feel free to reuse our input setup code, including the tooltip providing users with explanations on how it works for them. We make a simple call to request.security_lower_tf() to fetch the close values of intrabars, but we do not use those values. We simply send the returned array to `ltfStats()` and then plot in the indicator's pane the number of intrabars examined on each bar and its average. We also display an information box showing the user's selection of the ​LTF calculation mode, the resulting ​LTF calculated by `ltf()` and some statistics. █   NOTES  • As in several of our recent publications, this script uses secondsToTfString() to produce a timeframe string in timeframe.period format from a timeframe expressed in seconds.  • The script utilizes display.data_window and display.status_line to restrict the display of certain plots.   These new built-ins allow coders to fine-tune where a script’s plot values are displayed.  • We implement a new recommended best practice for tables which works faster and reduces memory consumption.   Using this new method, tables are declared only once with var , as usual. Then, on bar zero only, we use table.cell() calls to populate the table.   Finally, table.set_*() functions are used to update attributes of table cells on the last bar of the dataset.   This greatly reduces the resources required to render tables. We encourage all Pine Script™ programmers to do the same. Look first. Then leap. █   FUNCTIONS The library contains the following functions: ltf(userSelection, choice1, choice2, choice3, choice4, choice5, choice6, choice7, choice8)   Selects a ​LTF from the chart's TF, depending on the `userSelection` input string.   Parameters:      userSelection : (simple string) User-selected input string which must be one of the `choicex` arguments.      choice1 : (simple string) Input selection corresponding to "Least precise, covering most chart bars".      choice2 : (simple string) Input selection corresponding to "Less precise, covering some chart bars".      choice3 : (simple string) Input selection corresponding to "More precise, covering less chart bars".      choice4 : (simple string) Input selection corresponding to "Most precise, 1min intrabars".      choice5 : (simple string) Input selection corresponding to "~12 intrabars per chart bar".      choice6 : (simple string) Input selection corresponding to "~24 intrabars per chart bar".      choice7 : (simple string) Input selection corresponding to "~50 intrabars per chart bar".      choice8 : (simple string) Input selection corresponding to "~100 intrabars per chart bar".   Returns: (simple string) A timeframe string to be used with `request.security_lower_tf()`. ltfStats()   Returns statistics about analyzed intrabars and chart bars covered by calls to `request.security_lower_tf()`.   Parameters:      intrabarValues : (float [ ]) The ID of a float array containing values fetched by a call to `request.security_lower_tf()`.   Returns: A 3-element tuple: [ (series int) intrabarsInChartBar, (series int) chartBarsCovered, (series float) avgIntrabars ].

Chaikin Money Flow - LibraryLibrary "Chaikin Money Flow" cmf() 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 of Money Flow Volume, Chaikin Money Flow simply 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. Chartists can also look for crosses above or below the zero line to identify changes on money flow. The Accumulation Distribution Line was developed by Marc Chaikin to measure the cumulative flow of money into and out of an index or security. The Accumulation/Distribution Line can be compared to the OBV (On Balance Volume), which adds or subtracts volume depending on the closing price. Marc Chaikin chose a different approach, instead of relying on the closing price, he used CLV (Close Location Value).

Demand IndexLibrary "DemandIndex" di() The Demand Index is a complex technical indicator that uses price and volume to assess buying and selling pressure affecting a security. James Sibbet established six rules for using Demand Index when the technical indicator was originally published. While traders may use variations of these rules, they serve as a great baseline for using the indicator in practice. The six rules are as follows: A divergence between the Demand Index and price is a bearish indication. Prices often rally to new highs following an extreme peak in the Demand Index. Higher prices with a low Demand Index often indicate a top in the market. The Demand Index moving through the zero line suggests a change in trend. The Demand Index remaining near the zero line indicates weak price movement that won’t last long. A long-term divergence between the Demand Index and price predicts a major top or bottom. Traders should use the Demand Index in conjunction with other technical indicators and chart patterns to maximize their odds of success.
