Draw Vertical Line at Specified Bar

When you need to draw a vertical line on charts for better visual orientation you can use following code to do it:

Add this into EA Wizard / code / CustomFunctions.mq4 file. Then you can use it in Wizard as it is shown in example attached.

void drawVerticalLine(int barsBack) {
   
   string lineName = "Line"+MathRand();

   if (ObjectFind(lineName) != 0) {
      ObjectCreate(lineName,OBJ_VLINE,0,Time[barsBack],0);
      ObjectSet(lineName,OBJPROP_COLOR, clrRed);
      ObjectSet(lineName,OBJPROP_WIDTH,1);
      ObjectSet(lineName,OBJPROP_STYLE,STYLE_DOT);
   }
}

And use it as shown in the example attached.

The example draws a line on selected chart every day at 8 o’clock

Hello,

when I exported Drawverticalline.mq4 as an EA it works for me – see pic attached. I see an error on your screenshot in the bottom. Does it appear when you run the code?
