    Compared are arrays of simple types or custom structures without complex objects (strings, dynamic arrays, classes or other structures with complex objects). This function works only with arrays of the same type src1 and src2. When src1 is of type char and src2 is of type uchar, the error 302 "type mismatch" will occur.

  2. Added the CHART_IS_OBJECT chart property (for the ChartGetInteger function) - it indicates that a chart is the "Chart" graphic object.
  3. Added the CHART_MOUSE_SCROLL chart property (for the ChartGetInteger and ChartSetInteger functions) - it enables/disables scrolling of chart using a mouse. This property can be used when implementing graphical user interface in MQL5 programs.
  4. Fixed an error that in some cases led to a stack overflow during MQL5 programs execution.
  5. Changed OpenCL benchmark system: when OpenCL device(s) configuration is changed (including at the first run), terminal runs a test that determines device(s) performance and stores information in the registry.

    To automatically select the most efficient device, call the function of creating OpenCL context and specify CL_USE_ANY as the device number.

  6. Fixed the 'invalid EX5' message when using template functions.

  5. Fixed navigation through a chart in case of a specified fixation point.
  6. Fixed the terminal operation in corporate networks having proxy servers.

Trading Signals

  1. Added automatic conversion of EURUSD* type Forex trading symbols. If a signals source has positions at EURUSD! symbol, while a subscriber trades on EURUSD (or vice versa), the terminal will automatically detect the similarity of the trading symbols changing their names when copying the signal.
  2. Added display of active orders and signal positions in the signal's description.

    Added display of active orders and signal positions in the signal's description.

  3. Added the dialog of consent to synchronize positions on a subscriber's account with signal's ones in case of a positive floating profit on a signal provider's account:

    Added the dialog of consent to synchronize positions on a subscriber's account with signal's ones in case of a positive floating profit on a signal provider's account

    By default, synchronization is allowed only if the floating profit on the provider's account is not positive. This ensures that the signal subscriber can enter the market at a price that is not worse than the provider's one during synchronization of positions. Thus, the appropriate dialog window is shown before synchronization where traders can enable forced synchronization of positions with the signal, despite the positive floating profit.

  4. Added the dialog of automatic closing of positions and orders on a subscriber's account before synchronizing with signal provider's positions and orders:

    Added the dialog of automatic closing of positions and orders on a subscriber's account before synchronizing with signal provider's positions and orders

    Before synchronization, subscribers should close positions and remove orders opened manually or based on another signal. If open positions or pending orders unrelated to the provider's signals are detected, the client terminal will offer to remove all pending orders and close all positions automatically at the current price. However, traders can perform all necessary actions manually.


  1. Added support of template functions and methods.

    Templates can be compared with a macro (#define) representing an entire function instead of an expression. A template is inserted into the code in case the template function is called based on this call's parameters.
    A separate function (with its own static variables) is added by the compiler for each of the existing sets of the template function call's parameters present in the code.

    Example of the template function for calculation of the array's highest value:
    template<typename T>                       // В < > указываются параметры шаблона через запятую, не более 8.
    T ArrayMax(const T &data[],const T defval) // В качестве параметра может выступать только тип
       T    result=defval;
       uint size  =ArraySize(data);
       for(uint i=0;i<size;i++)
    Keep in mind that automatic reduction of parameters is not allowed when a template function is called. The parameter type should be clearly defined. For example, when calling ArrayMax function for char type array and CHAR_MIN as defval, the second parameter's type should be clearly defined as char:
    char a[];
       Print(ArrayMax(a,CHAR_MIN));       // ошибка, невозможно применить шаблон, т.к. T может быть или char или int
       Print(ArrayMax(a,(char)CHAR_MIN)); // ошибки нет, параметр шаблона T может быть только char
    Number of template parameters cannot exceed 8. Insertion of templates into the code is performed only by call parameters, evident template typification is not performed.
    Example of evident typification:
    Print(ArrayMax<char>(a,CHAR_MIN));  // Явная типизация шаблона пока не доступна!
  2. Enhanced integer properties received by CLGetInfoInteger function:

    • CL_DEVICE_VENDOR_ID  - OpenCL device vendor ID
    • CL_DEVICE_MAX_COMPUTE_UNITS  - number of OpenCL device computational units
    • CL_DEVICE_MAX_CLOCK_FREQUENCY - frequency of OpenCL device computational units
    • CL_DEVICE_GLOBAL_MEM_SIZE - size of the global memory of OpenCL device
    • CL_DEVICE_LOCAL_MEM_SIZE - size of the local memory of OpenCL device

  3. Added CLGetInfoString returning the following OpenCL properties:

    • CL_PLATFORM_PROFILE - OpenCL platform profile type
    • CL_PLATFORM_VERSION - OpenCL platform version
    • CL_PLATFORM_NAME - OpenCL platform name
    • CL_PLATFORM_VENDOR - OpenCL platform vendor name
    • CL_PLATFORM_EXTENSIONS - OpenCL platform possibilities (extensions)
    • CL_DEVICE_NAME - OpenCL device name
    • CL_DEVICE_VENDOR - OpenCL device vendor name
    • CL_DRIVER_VERSION - OpenCL device driver version
    • CL_DEVICE_PROFILE - OpenCL device profile type
    • CL_DEVICE_VERSION - OpenCL device version
    • CL_DEVICE_EXTENSIONS  - OpenCL device possibilities (extensions)
    • CL_DEVICE_OPENCL_C_VERSION - supported version of OpenCL compiler
  4. Added CLExecute overload function allowing users to specify dimensions of OpenCL local space of tasks.
  5. Fixed ArrayFill function operation.
  6. Removed warning when using an uninitialized variable in sizeof() function.
  7. Improved  __FUNCSIG__ macro - added notification of the fact that parameters are arrays, as well as of their constancy.
  8. Standard Library. Fixed CCanvas::FillRectangle method.
  9. Standard Library. The classes for working with files are transformed using template methods.
  10. Standard Library. Added support of operator [] in CArray* dynamic array classes.
  11. Standard Library. Enhanced CCheckGroup class methods - "checkbox group" control element.
  12. Standard Library. Added CIndicator::BarsCalculated method.

Strategy Tester

  1. Added the tester's compatibility with Wine.
  2. Added additional checks for disk errors during the tests.
  3. Fixed generation of week bars for trading symbols with a quote session on Sundays.
  4. Fixed generation of week and month bars - the bar time has sometimes been set incorrectly.
  5. Cloud agent having less than 100 megabytes of available disk space cannot execute the tasks.
  6. Removed log messages on charging commission during optimization.
  7. Fixed settings dialog behavior when testing an indicator.
  8. Fixed optimization chart display in case of a large number of passes.

MetaTrader 5 Trading Terminal build 705

Trading Terminal

  1. The MetaTrader 5 Trading Terminal has been integrated with the MQL5.Signals service. Now every MQL5 account holder can subscribe to trading Signals Sources, including the Automated Trading Championship 2012 participants.

    Moreover, the Client Terminal will copy trading signals with minimum delays according to the signal settings.

    Control of signals in the MetaTrader 5 Trading Terminal

    The list of signals in the MetaTrader 5 Trading Terminal

    The report on signals in the MetaTrader 5 Trading Terminal

    One trading account on the broker's trade server can be subscribed to only one Signals Source at a time. To change the Signals Source, the active subscription has to be revoked.

    Before the Signal is copied, client's positions undergo the initial synchronization with the positions of the Signals Source. There shall be no orders or positions in the client account of the Subscriber that were opened by the client or based on the Signal from another Signals Source. Moreover, the initial synchronization is only possible in case the total floating profit of the Signals Source is not positive, thus the Subscriber will enter the market at the price which is not worse than that at which the Signals Source entered the market.

    The synchronization initiates the opening of the client's positions in the same direction and trading instrument as the positions of the Signals Source. The opening position volume is determined according to the money management settings. The positions are opened using market orders with slippage specified in the settings. SL and TP levels are also copied, unlike pending orders that are not copied.

    Further copying of the Signal is subject to successful synchronization the results of which are recorded in the terminal log labeled "Signal".

    Following the successful initial synchronization, new transactions in the account of the Signals Source are copied again by performing the same transactions in the client account of the Subscriber using market orders. The order volume and slippage are determined according to the settings. Changes in the SL and TP levels for open positions are also copied. All actions associated with the copying of the signal are recorded in the terminal log labeled "Signal".

    The copying of signals does not provide for the possibility of concurrent trading either manually or using an Expert Advisor. Any results of copying the signal are incalculable after such interference.

    If an error occurs when copying the signal - connection failure, order placing error, etc. - the account will again be synchronized with the Signals Source.

    The signal settings require the specification of the money management, i.e. the algorithm for determining the volume of transactions with respect to the volume of transactions of the Signals Source:

    • Automatic - the volume is determined in proportion to the Subscriber's and Signals Source's balance ratio.
    • Percentage based - the volume is determined as a specified percentage of the signal's volume in the Signals Source.

    Trading operations are performed with a permissible slippage set by the "Slippage" parameter that is expressed in spreads of a trading instrument.
    The copying of the signal will stop automatically if Equity falls below the level specified in the settings. All previously opened positions will in this case get closed.

  2. Fixed setting SL and TP values in the position modification dialog for instruments with a fixed tick size.
  3. Fixed handling commands for arranging chart windows horizontally and vertically
  4. Fixed the display of the purchased Product list in MQL5.Market.

  1. Changed the order of calling the constructor of an object returned by the function:
    Formerly, the constructor has been called by default before the function returning an object, while the copy operator has been called inside the function for return.
    Now, the appropriate constructor, copy constructor or default constructor calling the copy operator are called in return operator for an object returned from the function.
  2. Fixed a typo in one of the ENUM_SERIES_INFO_INTEGER enumeration values (SERIES_SYNCRONIZED -> SERIES_SYNCHRONIZED). Please make changes in the codes where the value is used.

  1. MetaEditor: Added support for projects in

    Projects allow programmers to develop MQL5 applications in teams. Teamwork is performed via MQL5 Storage. It means that a user should have an active account on and connect to MQL5 Storage.

    Projects in

    Projects folder in MQL5 directory has been implemented for common projects. It is shown in blue in Navigator.
    Despite the fact that Projects folder is located inside MQL5, the projects are located separately from the user's personal directory (< account>/MQL5).
    All projects are stored in a separate section

    The top-level directory in Projects folder is considered to be a project. Therefore, a new folder should be created in Projects section to create a project. Use "New Folder" option to create the new folder, select it and click "Create Project" in the context menu.
    The project will be created. Reports on successful project creation will be displayed in MetaEditor's journal.

    Access to each project is set only by a project author (a user who created it).
    To start a teamwork on a project, you should allow other users to access it. Click "Add Permission" in the context menu of a created project folder and add a new user by specifying his or her login.

    Collaboration over the project in MetaEditor

    Click "Checkout" in "Projects" folder context menu to upload available projects. The projects will be uploaded from the storage. All further operations with them are similar to the ones with conventional files assigned to MQL5 Storage.

  2. Fixed MetaStyler operation - considering interline alignment for the lines beginning from #.
  3. Fixed errors occurred when working with MQL5.Strorage.

  5. Fixed display of internal emails and news under Windows XP with Internet Explorer 6.0.
  6. Fixed search on website when working in older Windows XP versions.
  7. Updated translation of the client terminal into Bulgarian.


  1. Added request_id field in MqlTradeResult structure - a unique identifier of the terminal trade request during a network session.

    This field is filled by the client terminal when a trade request is successfully sent to the server. Further on, this field is filled in result parameter of OnTradeTransaction entry point. Therefore, the opportunity of clear comparison of OrderSend and OrderSendAsync functions calling with getting the trade request results at OnTradeTransaction entry point is provided.

  2. Added compatibility of ex5 programs with DLLs created using .NET.
  3. Fixed optimization of the functions that return the structures.
  4. Added operation signs in the profiler mode:
    • IS_PROFILE_MODE - macros determining MQL5 program compilation in the profiling mode
    • MQL5_PROFILER - new value of ENUM_MQL5_INFO_INTEGER enumeration - determining the programs operation in the profiler mode. MQL5InfoInteger function should be used to get the value.
  5. Disabled inlining of large volume functions leading to excessively large EX5 files.
  6. Standard Library. Added SetTransparentLevel transparency management method to CCanvas class.
  7. Added the new sinput (static input) key word preventing manual input of values for searching an input parameter during optimization.
  8. Added ParameterSetRange(string name, bool enable, double value, double start, double step, double stop) function, which allows redefining the very possibility of searching the values, as well as the range of searched values before launching the optimization. The function can be called only from OnTesterInit handler. The function can also be applied to the input parameters protected by sinput key word.
  9. Added ParameterGetRange(string name,bool& enable, double& value, double& start, double& step, double &stop) function. It can be called from OnTesterPass and OnTesterDeinit handlers.


  1. Fixed automatic saving of all open files before the compilation.
  2. Added the snippet for OnTradeTransaction entry point.

    For ease of writing code, MetaEditor provides the possibility to insert snippets — small template fragments of source code describing a particular construction of the MQL5 language. Insertion of a snippet is initialized by typing the keyword. After you type the keyword the cursor is changed to "Snippet available". To insert a snippet, you should press "Tab". For more information about working with snippets please read the MetaEditor Help.

    The key word for OnTradeTransaction entry point is OnTradeTransaction.

  3. MQL5.Storage - fixed MQL5 Storage errors related to determining the presence of changes.
  4. Fixed results display for the "inline" code in the profiler.
  5. Fixed search on website when working in older Windows XP versions.

Strategy Tester

  1. Removed the limit of 63 simultaneously optimized parameters.

    All input parameters can now be included for optimization (the number of input parameters is limited by 1024). It means that the space that can have the maximum value to be written in the integer 1024-bit value can be used in the genetic search for the optimal parameters. The protocol of data transfer between the terminal and tester agents has been changed for big indices of the optimized variants.

MetaTrader 5 Client Terminal build 674

Trading Terminal

  1. Added the ability to post screenshots of charts on When saving a screenshot, just select the appropriate option and the screenshot will be automatically placed on, while a trader will get its address for posting on other websites and forums.

  2. Improved the algorithm of a trend line inclination angle calculation.
  3. Fixed display of available bars number in a chart tooltip.
  4. Fixed display of news with the same publication time.
  5. Added support for canceled deals display.
  6. Fixed display of close button when closing a deal with a volume less than the minimum allowed one.
  7. Fixed spread and tick volume calculation in charts generated by the terminal.


  1. Added OnTradeTransaction entry point - getting information about trade transactions performed for a trade account.

    void OnTradeTransaction(const MqlTradeTransaction& trans,const  MqlTradeRequest& request,const MqlTradeResult& result)

    The entry point is called to transfer the data on the trade transactions performed for a trade account to MQL5 program:

    • adding, modifying, deleting open orders
    • adding, modifying, deleting orders in history
    • adding, modifying, deleting deals
    • modifying a position
    • execution of client's trade requests and getting the results.

    The client terminal stores the history of transactions and consistently transfers them to an Expert Advisor, if an entry point is present. The history is limited to 1024 transactions and cleared during the next connection.

    Note that transactions processing in the terminal is performed independent of transactions processing in MQL5 program. For example, while an Expert Advisor processes a transaction to add a new order, the terminal can at the same time get a transaction to delete the appropriate order and move it to history.

  2. Fixed making long screenshots of charts by MQL5 means (ChartScreenShot function).
  3. Fixed getting an empty last bar for the symbols built by Last prices.
  4. Added checking the presence of available history when executing request functions in synchronous requests of the price history.
  5. Added the function of ArrayFill numeric array filling. The function is an equivalent of memset C function and allows to initialize a memory area as efficiently as possible.
  6. Updated ENUM_SYMBOL_SWAP_MODE enumeration - swaps accrual parameters for open positions - new values added and part of previous ones renamed. Previous enumeration values are still supported for compatibility.
  7. MQL5: Enhanced ENUM_DEAL_TYPE "deal types" enumeration values set. The following values are added:

    • DEAL_TYPE_BONUS - depositing a bonus by a broker
    • DEAL_TYPE_COMMISSION - charging commission by a broker
    • DEAL_TYPE_COMMISSION_DAILY - charging commission by a broker according to trading day results
    • DEAL_TYPE_COMMISSION_MONTHLY - charging commission by a broker according to month results
    • DEAL_TYPE_AGENT_DAILY - depositing the agent's commission according to trading day results
    • DEAL_TYPE_AGENT_MONTHLY - depositing the agent's commission according to month results
    • DEAL_TYPE_INTERESTRATE - depositing accrued interest rate on free funds
    • DEAL_TYPE_BUY_CANCELED - canceled buy deal
    • DEAL_TYPE_SELL_CANCELED - canceled sell deal
  8. Standard Library. Added possibility to manage the list elements in CComboBox class.
  9. Standard Library. Added CCanvas class (MQL5\Include\Controls\Canvas.mqh).

    CCanvas class allows to implement various graphics on custom charts of "Bitmap" and "Bitmap Label" types. In fact, these objects turn into a surface for drawing any image. Thus, it is possible to create custom graphical objects, apart from the ready-made terminal ones.

    The class implements the functions for drawing lines, circles, rectangles, polygons, their filling and filling any area in a specified color. Besides, the client terminal distribution kit now has the example of the class application CanvasSample (MQL5\Scripts\Examples\Canvas\CanvasSample.mq5).

Strategy Tester

Added saving the intermediate data of the genetic optimization - the optimization process will start from where it was stopped, not from the beginning.


  1. Added MQL5 programs profiler - the built-in tool for gathering program parameters during its operation. Attention is paid to such parameters as functions execution time, number of functions calls, separate code fragments execution time. This tool allows programmers to analyze their application, find its critical parts and write more optimal code.

    Profiling results are exported in HTML, CSV and OpenXML formats. To move to a specific code line, just double-click on the appropriate profiling report line.

  2. Fixed comparing files with the contents of MQL5 Storage.

    Fixed errors reported in crash logs.
    Updated documentation.
