Delays in displaying vaules on the chart

I have an indicator that display values on the chart via  ChartObjects.DrawText and so far it is working except that it takes 30 seconds or so to display on the chart. Its ok if only one chart but if change timeframes and switch to other pairs, the delays becomes annoying.

What can I do to minimize the delays if not make it realtime as much as possible?

below are the screenshot and code for your further investigations.

thanks in advance.

using cAlgo.Indicators;

namespace cAlgo
{
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class test : Indicator
    {

        private CommodityChannelIndex _cci_daily;
        private CommodityChannelIndex _cci_4h;
        private CommodityChannelIndex _cci_1h;
        private CommodityChannelIndex _cci_30m;
        private CommodityChannelIndex _cci_15m;
        private CommodityChannelIndex _cci_5m;


        protected override void Initialize()
        {
            _cci_daily = Indicators.CommodityChannelIndex(MarketData.GetSeries(TimeFrame.Daily), 14);
            _cci_4h = Indicators.CommodityChannelIndex(MarketData.GetSeries(TimeFrame.Hour4), 14);
            _cci_1h = Indicators.CommodityChannelIndex(MarketData.GetSeries(TimeFrame.Hour), 14);
            _cci_30m = Indicators.CommodityChannelIndex(MarketData.GetSeries(TimeFrame.Minute30), 14);
            _cci_15m = Indicators.CommodityChannelIndex(MarketData.GetSeries(TimeFrame.Minute15), 14);
            _cci_5m = Indicators.CommodityChannelIndex(MarketData.GetSeries(TimeFrame.Minute5), 14);
        }

        public override void Calculate(int index)
        {

            ChartObjects.DrawText("1", xySpace(0, 1) + _cci_daily.Result.LastValue, StaticPosition.TopLeft);
            ChartObjects.DrawText("2", xySpace(0, 2) + _cci_4h.Result.LastValue, StaticPosition.TopLeft);
            ChartObjects.DrawText("3", xySpace(0, 3) + _cci_1h.Result.LastValue, StaticPosition.TopLeft);
            ChartObjects.DrawText("4", xySpace(0, 4) + _cci_30m.Result.LastValue, StaticPosition.TopLeft);
            ChartObjects.DrawText("5", xySpace(0, 5) + _cci_15m.Result.LastValue, StaticPosition.TopLeft);
            ChartObjects.DrawText("6", xySpace(0, 6) + _cci_5m.Result.LastValue, StaticPosition.TopLeft);



        }
        private string xySpace(int x, int y)
        {
            if (x < 0 || y < 0)
                return ("");
            string str = "";
            for (int i = 0; i < y; i++)
                str += "\n";
            for (int i = 0; i < x; i++)
                str += "\t";
            return (str);
        }
    }
