happytrader wrote:Hi all,

does anyone know of a script that allows you to drag and drop horizontal lines to the top or bottom of a candle you hover the mouse over.

I have found one that I can manually place lines on the extremes of candles but I would like one that attaches its self to the precise levels if anyone knows of one.

Any help appreciated.

int start()
  {
   //delete the old line
   ObjectDelete("MyHighLine");
   
   //get the high price of the dropped on bar
   double price = High[iBarShift(Symbol(),0,WindowTimeOnDropped())];
   //create the line
   ObjectCreate("MyHighLine", OBJ_HLINE, 0,WindowTimeOnDropped(),price);
   
   return(0);
  }

As it is I can have only one high line and one low line.

Thx.

edit: ie if I do this "//ObjectDelete("MyHighLine");" it will not draw another line.

Thanks to George I can get the lines to snap to the candle highs and lows, colour code them etc. but I just cannot work out how to get the data to draw onto the line on my chart automatically.

Formatted something like this on todays AUD/USD - H4-Low 2013.06.11 12:00 0.93249

Thanks again and all the very best to you and the gang.

Edited to add the code for a weekly support line

//+------------------------------------------------------------------+
int start()
{


//get the low price of the dropped on WEEKLY bar
double price = Low[iBarShift(Symbol(),0,WindowTimeOnDropped())];
//create the line
ObjectCreate("wsup", OBJ_HLINE, 0,WindowTimeOnDropped(),price);
ObjectSet("wsup",OBJPROP_COLOR,Turquoise);

// setting object visibility on Weekly chart and all timefames below.
ObjectSet("wsup", OBJPROP_TIMEFRAMES,OBJ_PERIOD_M1 |OBJ_PERIOD_M5 | OBJ_PERIOD_M15 | OBJ_PERIOD_H1 | OBJ_PERIOD_M30 | OBJ_PERIOD_H4 | OBJ_PERIOD_D1 | OBJ_PERIOD_W1 );

return(0);
}

Of course once you start adding unique strings, it makes deleting them harder... George

Thanks George. I'm now happy to just draw them on the one candle. What I've done is follow your instructions to create a high line, low line, open line and a close line and then once I got over the first lot of trial and error, made these four scripts into one. A few days later I've had another go and organised it better and added a mid line (middle of the body).

In use I have say a M15 chart, change the tf to D1, add the script to the last (closed) candle, then change the tf back to M15. Good to watch PA around these lines.
