General Add Toggle On/Off button to a GapFinder indicator

[cortyk]

Hi Guys,
Could someone add an ON/OFF button on this gap finder indicator I've recently modified?
I'm an amateur noobie programmer and I can only code basic things and this is getting pretty challenging for me.
I've tried to integrate and modify part of other codes with buttons template but no way.

This are the indicators inputs which are customizable

This is how it prints gaps on charts

#property indicator_chart_window
#property indicator_buffers 1
#property description "Automatically render boxes for liquidity gaps "
#property indicator_color1 Black

extern double Gap_Size_Minimum = 100;
extern int ExtendBars = 1000;
extern int    History = 1000;
extern color Gap_Up = Aqua;
extern color Gap_Down = Tomato;
input ENUM_LINE_STYLE Rectangle_Style = STYLE_SOLID;

double Pip;
int init()
  {
    Pip = Point;
   if(Digits==3 || Digits==5) Pip = 10*Point;
   return(0);
  }

int deinit()
  {
    string ObjName;
    for(int i = ObjectsTotal()-1; i>=0; i--)
    {
      ObjName = ObjectName(i);
      if(StringFind(ObjName,"liquidity_gaps",0)>=0)
        ObjectDelete(ObjName);
    }
    return(0);
  }

int start()
  {
   int i, limit, counted_bars=IndicatorCounted();
   limit = MathMin(History,Bars-counted_bars-1);
   string ObjName;
   for(i=limit; i>=0; i--)
   {
     if(i>Bars-2) continue;
     if(MathAbs(Open[i]-Close[i+1]) > Gap_Size_Minimum*Pip)
     {
       ObjName = "liquidity_gaps_Up_"+Time[i];
       color ObjColor;
       if(Open[i] > Close[i+1]) ObjColor = Gap_Up;
       else ObjColor = Gap_Down;
       if(ObjectFind(ObjName)<0)
       { 
         ObjectCreate(ObjName,OBJ_RECTANGLE,0,Time[i+1],Close[i+1],Time[i],Open[i]);
         ObjectSet(ObjName,OBJPROP_BACK,0);         
         ObjectSet(ObjName,OBJPROP_COLOR,ObjColor);                 
         ObjectSet(ObjName,OBJPROP_STYLE,Rectangle_Style);
       }
     }
    
     //datetime thistime = Time[i];     
     int ib = i+ExtendBars;
     while(ib>=0)
    
     {
       ObjName = "liquidity_gaps_Up_"+Time[ib];
       if(ObjectFind(ObjName)>=0)
       {
         double pr2 = ObjectGet(ObjName,OBJPROP_PRICE2);
         double pr1 = ObjectGet(ObjName,OBJPROP_PRICE2);
         ObjectSet(ObjName,OBJPROP_TIME2,Time[i]);
         ObjectSet(ObjName,OBJPROP_PRICE2,pr2);
       }
       ib--;
     }
   }
   return(0);
  }

Thanks in advance for you kind help
