By default MT4 platform doesn’t have chart undock feature. This is an extremely useful feature for users having multiple monitors and track stocks in multiple computer monitors simultaneously.
For MT4 Data Blaze users we give undock MT4 script for free. You have to just add the script to the symbol and the corresponding window gets undocked. Then you can drag and place the window in any other monitors. To re-dock, you have to just click the re-dock button at the top-left corner and the window get redocked.
