You can access settings by clicking on 

inside the main MT4Professional panel


The following window will open.



All settings are synchronized in the cloud, there are two kinds of settings: settings synced among all instances (general settings) and settings specified for the current instance (these instance settings).


General settings are:

  • Treat Empty as Zero: in fact on MT4 empty and 0 are two different values, however, some indicators return empty with a meaning of 0. Enabling this setting the empty will be treated as 0, so in the scanner, you can just compare empty values with 0. We suggest keeping it enabled.
  • Crosshair Enabled: if enabled the synced crosshair will be shown in all charts
  • Crosshair Color: the color of the synced crosshair will be shown in all charts 


As specific instance settings there are:

  • Symbol Prefix: If your broker adds a prefix to your symbols (eg. mEURUSD instead of EURUSD), add it here
  • Symbol Postfix: If your broker adds a postfix to your symbols (eg. EURUSDm instead of EURUSD), add it here
  • Scanner Speed: Set the scanner speed to scan all rules, if you set "fast" high computer resources usage may be required.
