 var prvdaySeries = MarketData.GetSeries(Symbol.Code.ToString(), TimeFrame.Daily);

 ChartObjects.DrawHorizontalLine("PreviousdayHigh1", prvdaySeries.High.Last(1), Colors.DarkGray, 1, LineStyle.Lines);
ChartObjects.DrawText("prvdayHtext1", "H " + prvdaySeries.High.Last(1).ToString(), index + 2, prvdaySeries.High.Last(1), VerticalAlignment.Top, HorizontalAlignment.Right, Colors.Red);

here is example for drawing horizontal line at level of previous day..and above line is text "H + previous day high level"

maybe this helps
