Drawing a line with two points

New comment
 

I would like to draw a simple line 10 points above from my entry.  But this line needs to start 2 candles ago and end 2 candles in front of my entry candle.

Is this possible? Can someone post a sample code?

Thanks!

Show your idea in a picture. Explain what is " my entry"?

  1. Of course, it's possible. Find the index of your entry bar. Get the time of two bars before. Get the time of two bar after. Draw your TLine. What's the problem?

  2. You haven't stated a problem, you stated a want. Show us your attempt (using the CODE button) and state the nature of your problem.

    We're not going to code it for you (although it could happen if you are lucky or the problem is interesting).

It is only an example

      Posicion.Select(Symbol());
      double PriceLine = Posicion.PriceOpen() + 10 * Point();

      datetime TimeStart = iTime(Symbol(), PERIOD_CURRENT, 2);

      datetime TimeEnd = Posicion.Time() + 2 * PeriodSeconds(PERIOD_CURRENT);


      string name = "myLine";
      ObjectCreate(0, name, OBJ_TREND, 0, TimeStart, PriceLine, TimeEnd, PriceLine);
      ObjectSetInteger(0, name, OBJPROP_RAY, false);
      ObjectSetInteger(0, name, OBJPROP_COLOR, clrAqua);
     }
  }

It worked but it creates line sideway..

That is because you did not implement the example properly. Show your code so we can point out your error!

Ok I got it working but When I implement it on the On-tick function it slows down the chart. Anyone know how to fix this?

 
That's because you create hundreds of objects. On every tick.

Ok that makes sense. But how can I stop that from happening?
 
You need to track if you have created the object already or not.
