Indicator only drawing when time frames changed

[[Deleted]]

Can anyone help with this code, it compiles and 'works', but only draws the lines when time frames are changed,

#property copyright "Coded by Manic Miner"
#property indicator_chart_window
#property indicator_buffers 0
#property indicator_plots   0

input ENUM_TIMEFRAMES TimeFrame=PERIOD_M1;
input ENUM_LINE_STYLE LineStyle=STYLE_DOT;
input color LineColour=White;

//+------------------------------------------------------------------+
//| Expert initialization function                                   |
//+------------------------------------------------------------------+

datetime time1=TimeCurrent();
datetime time2=time1+60; 
datetime time3=time2+240;
datetime time4=time2+480;
double   openprice  = iOpen(NULL,TimeFrame,0);
double   highprice = iHigh(NULL,TimeFrame,0); 
double   lowprice = iLow(NULL,TimeFrame,0); 

int OnInit()
  {
//---

//---
   return(0);
  }
//+------------------------------------------------------------------+
//| Expert deinitialization function                                 |
//+------------------------------------------------------------------+
void OnDeinit(const int reason)

{

if(reason==1)

{

ObjectDelete(0,"High");
ObjectDelete(0,"Low");
ObjectDelete(0,"Open");

}
  
}

//+------------------------------------------------------------------+

void OnTick()
  {
//---

   
  }
//+------------------------------------------------------------------+

int OnCalculate(const int rates_total, 
                const int prev_calculated, 
                const datetime& time[], 
                const double& open[], 
                const double& high[], 
                const double& low[], 
                const double& close[], 
                const long& tick_volume[], 
                const long& volume[], 
                const int& spread[]) 
{ 
  
ObjectCreate(0,"High",OBJ_TREND,0,time3,highprice,time4,highprice);
ObjectSetInteger(0,"High",OBJPROP_COLOR,LineColour);
ObjectSetInteger(0,"High",OBJPROP_STYLE,2);
ObjectSetInteger(0,"High",OBJPROP_BACK,true);
ObjectCreate(0,"Low",OBJ_TREND,0,time3,lowprice,time4,lowprice);
ObjectSetInteger(0,"Low",OBJPROP_COLOR,LineColour);
ObjectSetInteger(0,"Low",OBJPROP_STYLE,2);
ObjectSetInteger(0,"Low",OBJPROP_BACK,true); 
ObjectCreate(0,"Open",OBJ_TREND,0,time2,openprice,time3,openprice);
ObjectSetInteger(0,"Open",OBJPROP_COLOR,LineColour);
ObjectSetInteger(0,"Open",OBJPROP_STYLE,0);
ObjectSetInteger(0,"Open",OBJPROP_BACK,true);  

return(rates_total); 

} 

Also in mql4, Time[0] can be used,

ObjectSet("High",OBJPROP_TIME2,Time[0]+(Time[0]-Time[2]));

But when I try this in mql5, it compiles, the lines are drawn, all the settings seem fine in Object List / Properties, but it is not visible,

ObjectCreate(0,"High",OBJ_TREND,0,time3,highprice,time[0]+(time[0]-time[2]),highprice);
