Virtual Hosting

1. Added a link to the tutorial video "How to Rent A Virtual Platform" into the Virtual Hosting Wizard dialog. Watch this two-minute video to learn how to easily launch a trading robot or copy signals 24/7.
   
   

   
   

   This video as well as many others is available on the official MetaQuotes Software Corp. YouTube channel.
2. Fixed migration for hosting when a custom indicator is called or an EX5 library within a custom indicator is called from an Expert Advisor.

Terminal

1. Accelerated update of the list of open orders and positions during high-frequency trading (50 and more operations per second).
   
2. Optimized and greatly accelerated initial synchronization of the terminal with a trade server in case of a large amount of symbols (tens of thousands). Now, you can start working much faster after connection is established.
   
3. Optimized and significantly reduced memory consumption by the terminal.
   
4. Added saving and restoring the depth of market settings when closing/opening the terminal.
5. Fixed artifacts that occurred in Windows 10 when dragging the terminal windows.
6. Fixed the context help for a number of commands and dialogs. For activating help concerning a certain element, move the cursor on it and press F1.
7. The works on adapting the interface for high resolution screens (4K) are underway.

MQL5

1. Added the new properties for the OrderGetString, HistoryOrderGetString, and HistoryDealGetString functions responsible for receiving data on orders and deals:
   
   
• ORDER_EXTERNAL_ID - order ID in an external trading system (on the exchange).
• DEAL_EXTERNAL_ID - deal ID in an external trading system.


2. Fixed the ZeroMemory function operation when working with structures and classes. Memory clearing was not performed in some cases.
3. Added the error codes during the SendFTP function operation. The function sends the file to the address specified on the FTP tab of the Options window.
   
   
   • ERR_FTP_NOSERVER - FTP server is not specified in the settings
   • ERR_FTP_NOLOGIN - FTP login is not specified in the settings
   • ERR_FTP_FILE_ERROR - file does not exist
   • ERR_FTP_CONNECT_FAILED - failed to connect to the FTP server
   • ERR_FTP_CHANGEDIR - file upload directory not found on the FTP server
     
   • ERR_FTP_CLOSED - connection to the FTP server closed
     
   
   
4. Fixed type casting access by inheritance between child class objects and their parents.
5. Fixed a few errors in the class templates.
6. Fixed requesting ticks using the CopyTicks function. When specifying the COPY_TICKS_TRADE parameter (copy only trade ticks) for consecutive identical trade ticks (identical volume and last price), only the first tick was passed.
7. Fixed defining a size of a custom type variable.
8. Fixed an error when using ZLib in the CryptDecode function that led to an infinite unzip loop.

Tester

1. Fixed synchronization of the price history for a symbol different from the main test one.
2. Fixed doubling of the TRADE_TRANSACTION_DEAL_ADD transaction (adding a trade to history) in the OnTradeTransaction event handler.
3. Changed forward test behavior during genetic optimization. Now, all unique results obtained after genetic optimization participate in forward passes. Previously, only 1/4 of the results were used.

MetaEditor

1. MetaEditor: Added a link to the tutorial video "How to Create a Trading Robot in the MQL5 Wizard" to the MQL5 Wizard. Watch this three-minute video and develop a trading robot without writing a single line of code.

   
   

   This video as well as many others is available on the official MetaQuotes Software Corp. YouTube channel.
2. Fixed window arrangement commands if one of the windows is fully expanded. The Window menu allows you to arrange open files as tiles, vertically, horizontally and as a cascade.
3. The works on adapting the interface for high resolution screens (4K) are underway.

1. Improved symbol chart zoom: increased the amount of zoom steps and enhanced display smoothness.
   
   

   

2. All changes in the set of symbols and their sequence in the Market Watch and chart settings (scale, color scheme, object and indicator lists) are saved after closing the application in any way.
   
3. Added a face value and accrued interest in bond properties.
   

Terminal

1. Terminal: Added ability to place limit orders at a price worse than the market one in the Depth of Market. This allows you to get a guaranteed order execution at a specified price on the market.
   
   If we drag a limit order through ask/bid border, it will change to a stop order (Buy Limit will be replaced by Buy Stop, while Sell Limit - by Sell Stop). Hold Crtl while dragging so that a limit order is not replaced by a stop one.
   

   
   
   

   
   
2. Terminal: Added the "Show quick trading buttons" option in the chart settings. It allows you to hide the One Click Trading panel enabling buttons and the Depth of Market from a chart.
   

   
   
   

   
   
3. Terminal: Fixed occasional conflicts between tooltips and other applications.

MQL5

1. MQL5: Fixed the operation of the Copy* functions for copying history data with dynamic arrays having the AS_SERIES flag. The flag is set by the ArraySetAsSeries function and indicates that indexation of the array elements is performed as in timeseries.
2. MQL5: Changed the CHART_SHOW_ONE_CLICK property managed via ChartSetInteger and ChartGetInteger. Previously, the property allowed showing/hiding the One Click Trading panel on a chart. Now, it also shows/hides the buttons for setting the One Click Trading panel and the Depth of Market on a chart (similar to the "Show quick trading buttons" in the chart settings).
   
3. MQL5: Fixed template operation.

Terminal

1. Added ability to work with tick history in the Market Watch. Previously, a tick chart showed only the history collected in the terminal during its operation. Now, you can access the entire tick history on the trade server. Disable auto scroll and start scrolling a tick chart back in time using your mouse to download missing history from the trade server the same way it is done for common price charts. The new feature will be useful for traders who want to get the most detailed price charts.
   

   
   
   

   Use the CopyTicks() function to receive deeper tick history. It has been modified so that it requests missing history and downloads it if the latter is present on the trade server.
   
   
2. Added an icon for quick opening/closing the Depth of Market. The icon is located near the One-Click Trading panel on the chart. You can also use the new hotkey Alt+B. The hotkey also works in the Market Watch window opening the Depth of Market for a symbol highlighted in the Market Watch.

   
   
   
   

3. Information about the PC hardware characteristics and the operating system is now logged to a Journal at the start of the client terminal. Example:
   

   2015.10.14 14:48:18.486	Data Folder: C:\Program Files\MetaTrader 5
   2015.10.14 14:48:18.486	Windows 7 Professional (x64 based PC), IE 11.00, UAC, 8 x Intel Core i7  920 @ 2.67GHz, RAM: 8116 / 12277 Mb, HDD: 534262 / 753865 Mb, GMT+03:00
   2015.10.14 14:48:18.486	MetaTrader 5 build 1190 started (MetaQuotes Software Corp.)

4. Imrpoved working with the symbols in the Market Watch:
   
   
   • Added display of the amount of symbols in the Market Watch and the total available amount of symbols on the trade server
   • Added a line for adding a new symbol with the smart selection list
     
   • The search in the new symbol line is performed not only by a symbol name, but also by its description and international name.
     

     
     
     

   
   
5. Added support for the economic calendar in different languages.
   
6. Added missing country icons to the economic calendar.
7. Added the hotkey for opening the symbol management window in the Market Watch - Ctrl+U.
8. Fixed arranging open chart windows according to the Window menu commands.
9. Fixed an error that occasionally hampered the terminal's ability to find a certificate file when using the enhanced authentication.
10. Fixed an error that could occasionally lead to a price history synchronization looping.
11. Fixed nulling StopLoss/TakeProfit levels of a previously opened position after its volume has been increased if a symbol is traded in the Request Execution mode.
12. Fixed checking the ability to place a sell order in case of a long position on symbols in "Long only" trading mode in the Depth of Market.
13. Fixed Trailing Stop function operation. In some rare cases, a protective Stop Loss for an open position was moved incorrectly.
14. The terminal interface has been further adapted for high resolution screens (4K).
15. Fixed unloading history data as being excessive despite regular appeals to it from MQL5 programs.
16. Fixed display of some user interface elements when working in Windows 10.
17. Updated translations of the user interface.

Market

1. Market: Operation with the product database in the MQL5 Market has been revised and optimized.
2. Market: Purchasing without an MQL5.community account has been disabled for terminals on VPS. The purchase now requires specification of an MQL5.community account in the terminal setting: Tools - Options - Community.
3. Market: Added direct product purchasing using UnionPay.
4. Market: Enhanced logging when purchasing products in MQL5 Market.
5. Hosting: Added managing the virtual hosting (except for migration) when working in the 32-bit version of the client terminal.

Virtual Hosting and Signals

1. Payments for Virtual Hosting and Signal subscriptions can now be transferred straight from payment systems. To pay for hosting services, users don't need to log in to the MQL5.community account and add money to it. A payment for a service can now be transferred straight from the platform using one of the available payment systems.
   

   
   
   

   Select one of the available systems and make an online money transfer:
   

   
   
   

   
   Similarly, a payment for a trading signal subscription can be made straight from the terminal via a payment system.
   

   
   
   

   
   The required amount will be transferred to your MQL5.community account first, from which a payment for the service will be made. Thus, you maintain a clear and unified history of rented virtual hosting platforms and signal subscriptions and can easily access and review all your payments for the MQL5.community services.
2. Added managing the virtual hosting (except for migration) when working in the 32-bit version of the client terminal.
3. Fixed migration of FTP export settings to the virtual hosting regardless of the permission to publish reports via FTP.

MQL5

1. Enabled a new optimizing compiler. Execution of programs has been accelerated up to 5 times on 64-bit platofrms. MQL5 programs should be re-compiled in the last MetaEditor version.
   
2. Extended MqlTick structure format. Now, it passes the time of a tick arrival in milliseconds, as well as flags to determine which tick parameter has been changed.
   

   struct MqlTick
     {
      datetime     time;          // Time of a price last update
      double       bid;           // Current Bid price
      double       ask;           // Current Ask price
      double       last;          // Current Last price
      ulong        volume;        // Volume for the current Last price
      long         time_msc;      // Time of a price last update in milliseconds
      uint         flags;         // Tick flags
     };

   The parameters of each tick are filled in regardless of whether there are changes compared to the previous tick. Thus, it is possible to find out a correct price for any moment in the past without the need to search for previous values at the tick history. For example, even if only a Bid price changes during a tick arrival, the structure still contains other parameters as well, including the previous Ask price, volume, etc. You can analyze the tick flags to find out what data have been changed exactly:
   
   
   • TICK_FLAG_BID - a tick has changed a Bid price
   • TICK_FLAG_ASK  - a tick has changed an Ask price
   • TICK_FLAG_LAST - a tick has changed the last deal price
   • TICK_FLAG_VOLUME - a tick has changed a volume
   • TICK_FLAG_BUY - a tick is a result of a buy deal
   • TICK_FLAG_SELL - a tick is a result of a sell deal
   
   The MqlTick structure is used in two methods:
   
   
   • CopyTicks - method does not support the old format of the structure. Previously compiled EX5 files using the old tick format will return the error 4006 (ERR_MQL_INVALID_ARRAY) when calling the CopyTicks function.
   • SymbolInfoTick - method supports both old and new structure format.
     
   
   
3. Added class templates allowing you to create parametrized classes like in C++. That enables even greater abstraction and ability to use the same code for working with objects of different classes in a uniform manner. Example of use:

   TemplTest (EURUSD,H1)    Ptr: 30 31 32 33 34 35 36 37 38 39
   
   
   
4. New operations * and & for receiving a variable by reference and receiving a reference to a variable.
5. Added the overloaded form of the ObjectsDeleteAll function - delete all objects of a specified type by a name prefix in a chart subwindow.
   

   int  ObjectsDeleteAll(
      long           chart_id,   // chart ID
      const string     prefix,   // object name prefix

6. Fixed the ObjectGetValueByTime function operation. Previously, an incorrect price value by a chart time could sometimes be returned (for example, for a horizontal trend line).
7. Fixed operation of the Copy* functions in the absence of historical data on the server. Previously, such cases caused delays of 30-50 seconds before returning control.
8. Added a few improvements to the MQL5 Standard Library.
9. Translated the Standard Library documentation into German, French, Chinese, Turkish, Spanish and Portuguese.
10. Added MQL5 documentation in Japanese.

Tester

1. The process of selecting programs to run in the Strategy Tester has become much easier. The list is displayed now as a tree in accordance with the directories in which Expert Advisors and indicators are stored.

   
   
   
   

2. Brought display of some indicators during a visualized test in line with the client terminal.
   
3. Fixed setting a leverage and a chart timeframe while debugging MQL5 programs via the strategy tester.
4. Fixed debugging indicators when testing on history.

Updated documentation.

• Added support for a special type of non-tradable instruments, which can be used as the client's assets to provide the required margin for open positions of other instruments. Such assets are displayed as open positions. They increase the free margin amount, thus increasing the volumes of allowable trade operations on the account.
• New interface language: Hindi.
• Various bug fixes and improvements.

Market

1. We are introducing a new mechanism of "direct" purchasing. Purchasing a trading robot or an indicator from the Market is now even easier, and you do not even need an MQL5.community account.
   
   One-Step Purchase
   A user doesn't need to log in to an MQL5.community account and add money to it. A payment for a product can now be made straight from the platform using one of the available payment systems. To maintain a clear and unified history of purchases from the Market, the required amount will be first transfered to your MQL5.community account, from which a payment for the product will be made.
   
   You can easily access and review all your payments from your MQL5.community Profile.
   

   
   
   

   
   Purchase without Registration
   A product from the Market can be purchased without an MQL5.community account. Click "Buy" and pay for the product using one of the available payment systems.
   

   
   
   

   Then you will be redirected to the payment system web page to complete your purchase.
   

   
   
   

   After that, we strongly recommend you to register an account on MQL5.community, and your purchase will be automatically linked to it. This enables you to update the product and install it on multiple computers.

MetaEditor

1. New features allow to debug Expert Advisors and indicators on history prices. In the older versions debugging required live real time charts.
   
   Now any program can be tested on required history data. Debugging runs in the visual testing mode in the Strategy Tester. An application is executed on a chart with an emulated sequence of ticks in the tester.
   
   Configure the debugging parameters in the MetaEditor settings: symbol, timeframe, interval, execution mode, tick generation mode, initial deposit and leverage. These parameters will be applied for visual testing.
   

   
   
   

   Set the breakpoints in the code, and then start the debugging using historical prices.
   

   
   
   

   This will initiate visual testing and the debugging process.
   

   
   
   

Virtual Hosting

1. Multiple improvements and fixes have been implemented in the Virtual Hosting service.
   
   The major changes apply to operation in Wine on computers running Linux and Mac OS. All the functions are available for allocated virtual servers in Wine, including migration, performance monitoring and logs.
   
   

   
   

   The operation of the Log has also changed. If a user requests too many records, then only part of the first logs for the specified period will be downloaded. This prevents performance degradation resulting from large logs. If you need to download further logs, you no longer need to change the requested period. Simply select the last row in the log viewer window and press PgDn.
   

   
   
   

   
   

Terminal

1. Added support for a special type of non-tradable assets, which can be used as client's assets to provide the required margin for open positions of other instruments. For example, a certain amount of gold in physical form can be available on a trader's account, which can be used as a margin (collateral) for open positions.
   
   Such assets are displayed as open positions. Their value is calculated by the formula: Contract size * Lots * Market Price * Liquidity Rate.
   
   Liquidity Rate here means the share of the asset that a broker allows to use for the margin.

   
   The Assets are added to the client's Equity and increase Free Margin, thus increasing the volumes of allowable trade operations on the account.
   

   Thus, it is now possible to open accounts with various margin types.

   
   

   In the example above, a trader has 1 ounce of gold having the current market value of 1 210.56 USD. This value is added to the equity and the free margin allowing the trader to continue trading even in case of a zero balance.
   
   
2. A new Depth of Market with a tick chart and the Time&Sales data of trades.
   
   A tick chart of exchange instruments with real transaction prices is now displayed in the Depth of Market. All transactions conducted on the Exchange are plotted on this chart:
   
   
   • Red circles - Sell transactions
   • Blue circles - Buy transactions
   • Green circles - the direction of the transaction is undefined. It is used when the exchange does not transmit the direction of a transaction. In this case, the direction is determined based on the price of the transaction as compared to prices bid and ask. A Buy transaction is that executed at the ask price or above, a Sell transaction is executed at the bid price or lower. The direction is undefined, if the price of the transaction is between the bid and the ask.
     
   
   The larger the circle, the greater is the volume of the transaction. Transaction volumes are also shown as a histogram below the tick chart.
   

   
   
   

   At the top and bottom of the histogram, the total volumes of the current Buy and Sell offers are shown.
   
   
3. The symbol selection dialog box now contains a column showing the symbol expiration date. Additionally, expired instruments can be hidden from the list. Expired contracts are automatically replaced with active ones.
   

   
   
   

   All expired symbols are hidden to preserve a more compact display. This is particularly useful when working on the futures market. A non-relevant symbol is the expired one, which is defined by the "Last trade" parameter. This date is specified in the "Expiration" column. To see all the symbols, click "Show expired contracts".
   The list of symbols is automatically sorted for a more convenient display:
   
   
   • first listed are the symbols without the expiration date
   • they are followed by the symbols with an expiration date starting with the nearest date
   • then expired symbols are shown starting with the last expired one
   • other symbols sorted alphabetically
   
   Option "Auto remove expired" in the context menu allows to replace expired symbols with active ones in the "Market Watch" window.
   

   
   
   

   After terminal restart, expired symbols are hidden, and active ones are added instead. For example, the expired futures contract LKOH 3.15 will be replaced by the next contact of the same underlying asset LKOH 6.15.
   
   Symbols in the appropriate open charts are also replaced, provided there are no running Expert Advisors on them.
   
   
4. Fixed updating of trade button states in the Depth Of Market window depending on whether there are any positions, and on the permission to open only long positions.

Trading Terminal

1. Preparatory works for virtual hosting support in MetaTrader 5 platform. Virtual hosting service allows you to rent a terminal that operates around the clock with no interruptions directly from your MetaTrader 5. One of the main features is selection of a server located closest to the broker's server minimizing network latency.
   

   
   
   

   
   

2. Tester agents now can work only in the 64-bit systems. This decision is driven by the need to follow the development of the IT industry. Switching to the new technologies increases computing performance and enables further development of MQL5 Cloud Network.

   
   
   

   Changes in the platform components:
   

   • Remote agents and MQL5 Cloud Network agents are no longer available for use in the 32-bit terminals. Instead of the agent list, "Available only in the 64-bit version" message is displayed.
   • MetaTester 5 Agents Manager is available only in the 64-bit version. Thus, it is possible to install the agents only on the 64-bit systems.

   
   

3. Fixed news filtration by language when the language list is specified manually in the terminal settings.
4. Optimized work with a large number of open orders.
5. Accelerated sending trade requests.
6. The interface has been adapted for high resolution screens - Full HD and higher.

1. Added the new form of WebRequest function:
   

   int WebRequest (string method, string url,string headers,int timeout, const char &data[], int data_size,char &result[], string &result_headers)

   This function allows you to explicitly form the contents of an HTTP request header providing more flexible mechanism for interacting with various Web services.
   
   
2. Added new trade account properties. The properties are available via AccountInfoDouble function.
   
   
   • ACCOUNT_MARGIN_INITIAL - current initial margin of an account.
   • ACCOUNT_MARGIN_MAINTENANCE - current maintenance margin of an account.
   • ACCOUNT_ASSETS - current account assets.
   • ACCOUNT_LIABILITIES - current account liabilities.
   • ACCOUNT_COMMISSION_BLOCKED - current blocked account commission.

Trading Terminal

1. Implementation of functions for trading options is currently underway. The Option Strategy Builder has been added. It helps users combine different options in one investment portfolio, and to assess the possibilities and potential risks.
   

   
   
   

   The Builder is easy to use: a trader chooses the option based on the expiration date and the underlying asset, and then selects one of the more than 30 available strategies. The Builder displays the appropriate combination of options and calculates evaluation parameters - the so-called Greeks. The profit/loss chart and the Greeks based chart appear at the bottom of the window.
   
   In addition to a large number of built-in strategies, traders can create and save their own strategies for later use.
   
   
2. Added display of the number of newsletters received in the last 24 hours.

8. Updated translation of user interface into German.
9. Added translation of user interface into Greek and Uzbek.

MQL5 Language

1. New function for working with the tick history CopyTicks. The function is used for receiving an array of ticks accumulated by the terminal for the current session. The depth is limited to the last 2000 ticks.
   
   The new function expands the possibilities for developing scalping trading robots. The OnTick function does not handle every tick, it notifies the Expert Advisor of market changes. It can be a batch of changes: the terminal can simultaneously make a few ticks, but OnTick will be called only once to notify the EA of the latest market state. The CopyTicks function allows you to receive and analyze all the ticks.
   

   int  CopyTicks(
      const string      symbol_name,           // Symbol name
      MqlTick           &ticks_array[],        // the array where ticks will be placed
      uint              flags=COPY_TICKS_ALL,  // the flag that defines the type of received ticks
      ulong             from=0,                // the date starting from which ticks will be received, specified in milliseconds since 01.01.1970
      uint              count=0                // the number of latest ticks that should be received
      );

   Ticks can be requested by the date if the 'from' value is specified, or based on their number using the 'count' value. If none of the parameters are specified, all available ticks are received, but not more than 2000. Ticks can also be requested based on their type using the 'flags' parameter. Available values:
   
   
   • COPY_TICKS_ALL - all ticks.
     
   • COPY_TICKS_INFO - only information ticks (Bid and Ask).
     
   • COPY_TICKS_TRADE - only trade ticks (Last and Volume).
     
   
   
2. Added an option for overloading template functions using array parameters.
3. Added an option for overloading a method based on its constancy.
   
4. Added generation of the CHARTEVENT_MOUSE_MOVE event (in the OnChartEvent entry point) at the right mouse button click on the chart.
5. Fixed the functioning of the Switch operator if the case condition contains a negative value.
6. Improved calculation accuracy in functions ObjectGetValueByTime() and ObjectGetTimeByValue(), used for receiving the price value for the specified object time and vice versa - time value for a price.
