Thank you
Your code works fine
I myself came to the answer in a different way

Bars bars_D1 = MarketData.GetBars(TimeFrame.Daily, Symbol.Name);
                Color color = "#24FE00FD";
                for (int i = 0; i < 200; i++)
                {
                    if (bars_D1.Last(i).OpenTime.Month != bars_D1.Last(i+1).OpenTime.Month)
                    {
                        rect = Chart.DrawRectangle("Candle_D1" + bars_D1.Last(i).OpenTime, bars_D1.Last(i).OpenTime, bars_D1.Last(i).High, bars_D1.Last(0).OpenTime, bars_D1.Last(i).Low, color);
                        rect.Comment = "Candle_D1";
                        rect.IsInteractive = true;
                        rect.IsFilled = true;
                    }
                }
