Moving HLine

1. Make up your mind "stay there on change of time frame or the pair" vs "does not reset to the current price,"
2. You can only create an object once, that is why it doesn't move. You would know that had you bothered to check your return codes: What are Function return values ? How do I use them ? - MQL4 forum
   
3. Either delete it and recreate it, or move it, or change the price. See my HLine/Tline code

As you contradict yourself, it is impossible to know exactly what you are asking.

However, I suspect that you DO want the line to change when changing the chart symbol

Not tested

string CurrentSymbol; //Variable declared on Global Scope

int init(){
   CurrentSymbol =Symbol();
   ObjectCreate("myHLineStop", OBJ_HLINE , 0, Time[0], Close[0]);
   ObjectSet("myHLineStop", OBJPROP_STYLE, STYLE_SOLID);
   ObjectSet("myHLineStop", OBJPROP_COLOR, Red);
   ObjectSet("myHLineStop", OBJPROP_WIDTH, 0);
   
   return(0);
}

int start()
   {
   if(CurrentSymbol!=Symbol())
      {
      CurrentSymbol=Symbol();
      ObjectMove("myHLineStop",0,Time[0],Close[0]);
      }
   
   ObjectGet("myHLineStop", OBJPROP_PRICE1);
   
   }

Thank you for the fast response.

Yes, you are right. Just to clear it up. I meant, that I want the HLine to stay where I have moved it, no matter what timeframe I switch. It shouldn't matter if I switch between 15M or 1H on the EURUSD Chart. The HLine should be at the position, where I have moved it f.e: 1,54000

The other thing is. If I change the currency pair to f.e. to GBPUSD then I would like to have a new HLine that I can move around and put it f.e. at 1,6678. When switching back to EURUSD I would like to find my HLine at 1,5400 no matter what time frame. When switching back to GBPUSD the HLine should be at 1,6678 no matter what time frame.

Thank you for the links. I will dive into them.

in that case you can't use Time[0] Close[0]

use iTime(Symbol(),PERIOD_..,0) iClose(..... )

Hi,

thank you very much for your support! I solved it with your help by using iTime and iClose and by creating objects for every single currency pair.

string sCurrentHLineName = "myHLineStop" + Symbol();

int init(){
  ObjectCreate(sCurrentHLineName, OBJ_HLINE , 0, iTime(Symbol(),0,0), iClose(Symbol(),0,0));
  ObjectSet(sCurrentHLineName, OBJPROP_STYLE, STYLE_SOLID);
  ObjectSet(sCurrentHLineName, OBJPROP_COLOR, Pink);
  ObjectSet(sCurrentHLineName, OBJPROP_WIDTH, 0);

  return(0);
}
