The function sets the value of the corresponding indicator property. Indicator property must be of the int or color type. There are two variants of the function.

Call with specifying the property identifier.

bool  IndicatorSetInteger(
   int  prop_id,           // identifier
   int  prop_value         // value to be set

Call with specifying the property identifier and modifier.

bool  IndicatorSetInteger(
   int  prop_id,           // identifier
   int  prop_modifier,     // modifier
   int  prop_value         // value to be set



[in]  Identifier of the indicator property. The value can be one of the values of the ENUM_CUSTOMIND_PROPERTY_INTEGER enumeration.


[in]  Modifier of the specified property. Only level properties require a modifier.


[in]  Value of property.

Return Value

In case of successful execution, returns true, otherwise - false.


Numbering of properties (modifiers) starts from 1 (one) when using the #property directive, while the function uses numbering from 0 (zero). In case the level number is set incorrectly, indicator display can differ from the intended one.

For example, in order to set thickness of the first horizontal line use zeroth index:

  • IndicatorSetInteger(INDICATOR_LEVELWIDTH, 0, 5) - index 0 is used to set thickness of the first level.

Example: indicator that sets color, style and thickness of the indicator horizontal lines.
