Duplicate indicator at timeframe change - MQL5 - page 2

[RedTaurus]

I tried other ways and so I solved for changing the TF. I still can't change the parameters Periods and Multiplier

input ENUM_TIMEFRAMES   TimeFrame   =  PERIOD_CURRENT;
input int               Periods     =  14;
input double            Multiplier  =  2.5;
int MyHandle = iCustom(_Symbol, TimeFrame, ".\MyIndicator", Periods, Multiplier);


OnInit()
        ChartIndicatorAdd(0, 0, MyHandle);
 
OnDeInit()
 
        ChartIndicatorDelete(0,0,MyHandle); 
        IndicatorRelease(MyHandle);

Could you show me an example to look at in order to better understand?
