MetaTrader 5 Build 1596: access to the price history

Terminal

1. Added access to the bar and tick history. Now, it is possible to download the full 1-minute and tick history from the server through the trading platform interface, not only using the MQL5 language. Access to price data is expanded as part of preparations for the launch of custom data-feed functions. In the near future, the platform will provide the possibility to build charts based on users' price data, as well as to create synthetic symbols and use offline charts.
   
   To download the data, open the symbol management dialog from the context menu of the "Market Watch" window:
   

   
   

   The dialog features two new tabs: "Bars" and "Ticks". Select the symbol, the desired time interval and click "Request". The platform will request from the server all available data, and will immediately display the data if they have already been downloaded. Saved price data can be exported to a CSV file.
   
   
2. Added display of time with a millisecond precision for positions, deals and orders.
   

   
   
   

   
   
3. In the trade dialog, fixed notifying about the refusal to execute a Close By request.
   

MQL5

1. Fixed the PositionSelect function. The function could occasionally select a position different from the one having the lowest ticket number.
2. Fixed operation of the CopyTicks and CopyTicksRange functions when requesting very deep tick history data.
   

Signals

1. Fixed copying of operations that increase the size of an existing position. The error could occasionally occur on netting accounts.
   

Tester

1. Fixed processing of limit orders for exchange instruments. Orders placed better than the market (the buy price is below the market price or the sell price is above that) are executed without slippage. Orders placed worse than the market or at the market price are executed immediately at the market price as of the order placing time.
