Volume Profile and Market Profile TPO (Time Price Opportunity) composition
Reference documentation for configuration options and methods of the Volume by Price Indicator a suite of technical analysis data visualization tools for MetaTrader 4 and 5 platforms.
For details on installation of the indicator, and optional extensions and resources see help center.
Configurations are made via the indicator properties window 'Inputs' tab by setting parameters.
The properties window opens after attaching an indicator instance to a chart:
To open the properties window of an instance already attached:
The basic approach is to select graphical object types, e.g., set parameter Object Main = Market Profile TPO - Marker Letter, Object Column = Volume Total and Object Column = Volume Profile - Histogram, and positions, e.g., Anchor Main = Segment - Start and Anchor Column = Segment - Start Left.
For the dataset, set range, segmentation, price level and TPO parameters, e.g., Dataset Range = 10 Days, Dataset Segment = Session, Dataset Price Level = 100 Symbol Points and Dataset Market Profile TPO = 48.
For further indications, select by on-object visualization, e.g., Highlight Main Market Profile TPO = Sequence and Highlight Column Volume Profile = Value Area, and/or by visualization method, e.g., Highlight Main Marker POC = Box Border and Highlight Main Marker VA = Box Border. For the Main object select additional indication elements, e.g., Highlight Main IB = Bar, Highlight Main OHLC = Candle and Highlight Main VWAP = Line. Display the Main Line objects as horizontal line, or line graph by chart timeframe period data points, e.g., Style Main Line Trace = true. For the extension object select type and indication, e.g., Extension Volume by Time Object = Histogram or Extension Volume by Time Object = Bubble Graph, and Extension Volume by Time Highlight = Delta. Panel object for numeric indications and details on dataset compilation, e.g., Panel = Summary Extended - Table and Panel = Dataset Information - Feed Statistics.
Set styling parameters by object type and/or visualization method. Size histogram and line graph object types of segments for absolute or relative indications, e.g., Style Column Histogram Size Segment = Relative. Indication context class color parameters, e.g., Style Main Color (positive) and Style Main Color (negative) for Highlight Main Volume Profile = Value Area to indicate Value Area and the range(s) higher and/or lower, or for Highlight Main Volume Profile = Delta with Evaluation Volume Buy/Sell = Price High/Low volume classes by close prices higher and lower. Set color parameters with the color picker. Default configuration with a palette of five colors a positive, negative, neutral, foreground and background color. For contrast on both dark and light themed charts, the foreground and background color parameter values, set to Gray, are automatically substituted to the chart's respective colors with Style Color Default Foreground/Background. Set color list parameters with presets, or specify as text value to type or create with included resources, e.g., Style Highlight Marker Color Sequence = Green,White,Gray and Style Background Color Gradient = Blue-Green-Red. Layer graphical objects above or below the native price chart, e.g., Layer Main = Background and Layer Column = Foreground. Composition multiple indicator instances from top to bottom by the order of attaching to the chart. Panel object display as text lines, table column rows or dashboards on the chart or a separate subwindow, e.g., Panel = Summary Extended - Line, Style Panel Raster Line = true and Style Highlight Panel Color Fill = Signed.
Chart property parameters for integrated chart control, i.e., settings of the chart properties window, and to make additional changes, e.g., to hide native price chart and/or scales. Default configuration with indicator keyboard shortcuts, optional on-chart control buttons, to toggle display of objects, switch types of the Main and Panel object, and to adjust price level size. For dataset range Drag & Drop to reset the range selection lines to the window visible range. Pair multiple Drag & Drop indicator instances with a shared Drag & Drop ID.
Default dataset compilation with millisecond accumulated real-time data ticks and lowest chart timeframe period historical data Dataset Real-time Ticks Accumulation = 100 Milliseconds and Dataset History Bars = All Timeframes. Historical tick data, and real-time and historical trade operation tick data with volume classification by order type with the included Tick Volumes and Order Book extensions via the Data Source API, e.g., attach a extension instance to a chart and set indicator parameter Dataset Feed = History Ticks + Real-time Ticks - Indicator API. Feed MetaTrader 5 terminal broker exclusive data, i.e., historical price tick and trade operation tick data, to MetaTrader 4 terminals, e.g., additionally set indicator parameter Data Source Common Folder = true, and Extension Order Book Output Common Folder = true and Extension Order Book Output Format = 4. Alternatively, feed user specified third party tick-by-tick or bar data files, e.g., stream of programmatically managed real-time tick-by-tick data Data Source = Feed.dat or user download of historical data Data Source = Feed.csv. Volume classification defaults to order type with fallback to price action Evaluation Volume Buy/Sell = Order Buy/Sell - Indicator API.
For high resolution price level Volume Profile, i.e., small price level size, especially on low chart timeframe or price scale, it is imperative to have sufficient data available for price level data points to have value, e.g., dataset range of 15 minutes on 1-minute timeframe chart can fill only 15 price levels at most with lowest chart timeframe period historical data whereas tick data at times can provide 1500 values to distribute. Maximum use of historical chart timeframe data of a broker is set with Max bars property via the terminal options window 'Charts' tab. To apply changes to the Max bars property restart the terminal.
Target real-time data processing interval, i.e., rate limit, for default data input with Dataset Real-time Ticks Accumulation, for the Data Source API with indicator and connector parameters, e.g., Data Source Input Rate = 50 Milliseconds and Extension Tick Volumes Output Rate = 50 Milliseconds. For compositions with multiple indicator instances, indicator instances do not process concurrently and only the first instance attached to the chart, which is last to process, controls frame display rate. Limit system resource usage further with Display Frame Rate.
Default configuration with adaptive data timeframe period selection Dataset History Bars Adaptive to prevent unintended high system resource usage such as with time based segmentation methods on change to higher chart timeframe or time scale. Warnings are displayed whether segmentation parameters were adjusted and/or dataset compilation quality was lowered. Preemptively favor speed over quality of historical chart timeframe period data distribution with the adaptive data timeframe period selection modes or select a single timeframe period, e.g., on high scale 4-hour timeframe chart Dataset History Bars Plan = Performance or Dataset History Bars = 15 Minutes.
Data Environment API for programmatic access to dimensions and metrics with Global Variables and file data output in segment and price level scopes. Extensions included to output segment scope volume, TPO and price metrics data to files in HTML, CSV, JSON and SQL formats, and price metrics as iCustom Buffers. Developer resources include a framework for automated algorithmic trading strategies, Data Environment API clients for MQL4 and MQL5 programming languages, and an event-model evaluation based extension.
Environment variable names can be selected and specified as values of input parameters with additional properties and options, and/or further distinction per metric, e.g., line visualization with user specified labels and style per metric Highlight Main Custom = VP_POC_MEDIAN:Volume Point of Control;propSize=3;propDash=1, etc, data statistics table Object Panel = Volume Point of Control %VP_POC_MEDIAN%; etc, and evaluation condition Extension Notifications Condition = VOLUME_DELTA > 500, etc.
Indicator data and configuration files are located in a subfolder named 'Volume by Price Indicator' in Data Folder MQL4|MQL5\Files of the terminal directory. Optionally, for selected functions data files in the Common Data Folder for shared use with other terminals on the operating system. Similarly optional, extensions and resources are located in 'Volume by Price Indicator' folders in each respective application and file type folder, i.e., Templates, Experts, Indicators, Scripts and Include. Access to files by MetaTrader 4 and 5 indicators is strictly controlled, terminals utilize the highest user security and privacy standards with a file sandbox for all applications types, no read or write permissions outside of the MQL4|MQL5\Files subfolders. For quick access to the terminal directory use command 'Open Data Folder' in the File menu of the terminal, for the Common Data Folder use command 'Open Common Data Folder' in the File menu of the MetaEditor.
Values of text input parameters can be set by reference to a configuration file. Specified paths are relative with optional use of chart property names for automatic data and configuration association, e.g., Market Profile TPO marker configuration Style Main Marker Character Letter = Market Profile TPO Letters.ini and Style Highlight Marker Color Sequence = Market Profile TPO Colors.ini, or dynamic segmentation configuration with automatic association by chart symbol name and timeframe period Dataset Segment Divisor = %SYMBOL%_%TIMEFRAME%.ini.
