Preliminary Announcement of the New MetaTrader 4 Build 491

New MetaTrader 4 client terminal is being prepared for release.

1. Terminal: Revised one click trading system:
   
   • When One Click Trading mode is enabled, the trading dialog is closed right after a successful operation. In case of an error, the dialog displays its cause.
     When One Click Trading mode is enabled, Close command in the position's context menu results in an immediate closing of the position without showing a trading dialog.
     

     
     
     

     
     
   • Added ability to drag and drop trading levels of orders and positions. To set SL and TP levels on position, just drag a trading level of an order upwards (TP for "BUY" positions) or downwards (SL for  "SELL" positions). When One Click Trading mode is enabled, dragging trading levels of orders and positions results in an immediate modification of the appropriate order or stop level without showing a trading dialog.

     
     
     
     

     
     Added the context menu for trading levels on the chart. The menu allows managing the level right from the chart.
