MQL5 Indicators - indicator_type property must be specified

[Anthony Garot]

Just double checking.

It appears that I can change any of the parameters dynamically, e.g. width, color, style, label, but I must have the indicator type as a compiler directive property, which does not ever change, e.g.

#property indicator_type1       DRAW_LINE

Is this correct?

Not according to Custom Indicators / Connection between Indicator Properties and Functions - Reference on algorithmic/automated trading language for MetaTrader 5

Directives for properties of indicator subwindow	Functions of IndicatorSet...() type	Description of the adjusted property of the subwindow
