Mql5官网 YFX Symbol Selector 外汇EA

The YFX Symbol Selector indicator is used to easily change the chart symbol and period with a click of a button. This is done by using a selector GUI object that can be placed on any corner of the chart. The GUI selector contains the following information:

• Descriptive header for GUI selector panel
• Symbol information and controls for changing the chart symbol
• Period information and controls for changing the chart period
• Footer containing the current bid/ask quote for the currently selected symbol

All the information can be displayed on the chart so that it can be easily read. The indicator also has parameters that can be set to customize which information is displayed. Parameters are organized into categories:

• Indicator
• Display
• Location
• Font
• Color

Also note that the categories are not mutually exclusive. Information may be applicable to multiple categories but will only be shown in one section for simplicity. All the parameters are assigned to default values that work fine in most cases. It is advised not to change default values until one becomes more familiar with the indicator.
