Demo_IndicatorSetString - MetaTrader 5 Script - MT4/MT5 Resources

An example of how to use indicatorSetString() . A simple indicator showing how to create labels such as "Overbought Level" for each level.

Using the #property compiler directive for indicators drawn in a separate window you can specify the desired horizontal level, for example:

 //--- display three horizontal levels in separate indicator windows
#Property Indicator Level 1 30
#Property Indicator Level 2 50
#Property Indicator Level 3 70

Additionally, the metricSetString() function can be used to add labels to each level and even change the labels dynamically if necessary:

 //--- Set the horizontal level description indicator set string ( INDICATOR_LEVETEXT , 0 , "First level (index 0)" );
Indicator set string ( INDICATOR_LEVETEXT , 1 , "Level 2 (index 1)" );
Indicator set string ( INDICATOR_LEVETEXT , 2 , "Third level (index 2)" );

notes

When using the #property directive, properties (modifiers) are numbered starting from 1 (one), and functions are numbered from 0 (zero). If the level numbers are set incorrectly, the resulting metrics may be different than expected.

For example, to set the description of the first horizontal level, use zero indexing:

 Indicator set string ( INDICATOR_LEVETEXT , 0 , "first level" )
//- Index 0 is used to set the first level text description.
