Objects Disappear problem

[Jack Buda]

Hi all, my objects disappear & after a few seconds or so they reappear again. If you know the problem please help.

void OnTick()
 {
  int Bottom=iLowest(Symbol(),0,MODE_LOW,75,1+40);
  
  ObjectDelete(0,"Bottom");
  ObjectCreate(0,"Bottom",OBJ_RECTANGLE,0,Time[0],Close[Bottom],0,Low[Bottom]);
  ObjectSetInteger(0,"Bottom",OBJPROP_COLOR,Green);
  
  int Top=iHighest(Symbol(),0,MODE_HIGH,75,1+40);
  
  ObjectDelete(0,"Top");
  ObjectCreate(0,"Top",OBJ_RECTANGLE,0,Time[0],Close[Top],0,High[Top]);
  ObjectSetInteger(0,"Top",OBJPROP_COLOR,Red);

 }

Maybe adding ChartRedraw() to the end of your code could help

You are deleting and recreating your rectangle each tick. Stop doing that. Create them once at the start of a new bar.

For a new bar test, Bars is unreliable (a refresh/reconnect can change number of bars on chart), volume is unreliable (miss ticks), Price is unreliable (duplicate prices and The == operand. - MQL4 programming forum.) Always use time.

I disagree with making a new bar function, because it can only be called once per tick (second call returns false). A variable can be tested multiple times.
