Easiest way to draw simple arrow

New comment
 

My EA identieifes certain trigger bars, I want a very simple arrow to be drawn above these bars. The code for arrows used in indicators seem quite complicated, is there not an easier way?

E.g. if previous bar close higher than bar before that I want to draw an arrow

if (NEWBAR)

if iClose(NULL,0,1) > iClose(NULL,0,2)

"DRAW ARROW ABOVE BAR 1"

Can anyone help with easy code to do this?

void DrawArrowUp(string ArrowName,double LinePrice,color LineColor)
{
ObjectCreate(ArrowName, OBJ_ARROW, 0, Time[0], LinePrice); //draw an up arrow
ObjectSet(ArrowName, OBJPROP_STYLE, STYLE_SOLID);
ObjectSet(ArrowName, OBJPROP_ARROWCODE, SYMBOL_ARROWUP);
ObjectSet(ArrowName, OBJPROP_COLOR,LineColor);
}

void DrawArrowDown(string ArrowName,double LinePrice,color LineColor)
{
ObjectCreate(ArrowName, OBJ_ARROW, 0, Time[0], LinePrice); //draw an up arrow
ObjectSet(ArrowName, OBJPROP_STYLE, STYLE_SOLID);
ObjectSet(ArrowName, OBJPROP_ARROWCODE, SYMBOL_ARROWDOWN);
ObjectSet(ArrowName, OBJPROP_COLOR,LineColor);
}

f.e. if iClose(NULL,0,1) > iClose(NULL,0,2) DrawArrowUp("Up"+Bar,Close[1]+10*Point,Lime);

if you draw more often on the same bar i would recommend to check first if the arrow already is existing on the chart and delete existing or set new values only...

 

Thanks so much EADeveloper!

 

Two problems:

1. Can I shift the arrow one bar to the left, i.e. on bar 1 not bar 0?

2. It seems to only draw the arrow the first time the condition is met, if conditions are met again a few bars later I get no arrow?

1 yes, change Time[0] to Time[1]

2 sorry ... DrawArrowUp("Up"+Bars,Close[1]+10*Point,Lime); i forgot the s from Bars before ...

 

Both problems solved, thank you again!

 

//how i can use the Arrow ?

//for example: 

//vline:


 void DrawVline8()

   

  {


    //Delet the last line

    ObjectDelete(_Symbol,"Line"[8]);

    

    //create a line object

    ObjectCreate(_Symbol,"Line"[8],OBJ_VLINE,0,TimeCurrent(),0);

    

    //set the object color

    ObjectSetInteger(0,"Line"[8],OBJPROP_COLOR,clrYellow);

    

    //set the object width

    ObjectSetInteger(0,"Line"[8],OBJPROP_WIDTH,4);


  }   

if

(A==1)

{

   DrawVline8() ;

}


//this is for vertical line

//But 

//i need like this for Arrow.

  3. Don't post code that will not even compile: "Line"[8] is babel.

  4. You need it for an arrow, change it to an arrow.

This program has no problems running

If you can not help, do not throw stones

I am using the same program in Expert.

And this is just an example of a vertical line.

  I need to use َArrow like this.

I wrote the complete program and only show the signals with a line.

I want to show it with an arrow now.

If you can conditionally run a program to draw the up and down arrow. If you do not know, let other people comment.
