An issue with multi timeframe code

I was trying to access adx stock indicator in another time frame other than the one Iam running my cbot on , it didn't seem to work as it did with the moving average indicator.
So I made an other adx that works just fine, but when I try to reference it in my cbot to use it, it keeps giving 0 as its value, when I initialize the indicator without trying to access an other timeframe it also works okay.

Here are the snippets from the Cbot

      //adx
       [Parameter("Period", DefaultValue = 1, MinValue = 1)]
        public int AdxPeriod { get; set; }

        [Parameter("MA Type", DefaultValue = MovingAverageType.Simple)]
        public MovingAverageType AdxMaType { get; set; }

      
      AdxS _Adx;
      
       protected override void OnStart() {
      
        var WeeklyTf = MarketData.GetBars(TimeFrame.Weekly);

     
         _Adx = Indicators.GetIndicator < AdxS > (WeeklyTf, AdxPeriod , AdxMaType);

and this is the indicator

using System;
using cAlgo.API;
using cAlgo.API.Internals;
using cAlgo.API.Indicators;

namespace cAlgo
{
    [Indicator("Custom ADX", IsOverlay = false, AccessRights = AccessRights.None)]
    public class AdxS : Indicator
    {
        [Parameter("Period", DefaultValue = 14, MinValue = 1)]
        public int Period { get; set; }

        [Parameter("MA Type", DefaultValue = MovingAverageType.WilderSmoothing)]
        public MovingAverageType MaType { get; set; }

        [Output("ADX", Color = Colors.Cyan)]
        public IndicatorDataSeries ADX { get; set; }

        [Output("DI+", Color = Colors.Green)]
        public IndicatorDataSeries DiPlus { get; set; }

        [Output("DI-", Color = Colors.Red)]
        public IndicatorDataSeries DiMinus { get; set; }

        private DataSeries high, low, close;
        private IndicatorDataSeries tr, dmPlus, dmMinus;
        private MovingAverage maTr, maDmPlus, maDmMinus;

        protected override void Initialize()
        {
            high = Bars.HighPrices;
            low = Bars.LowPrices;
            close = Bars.ClosePrices;

            tr = CreateDataSeries();
            dmPlus = CreateDataSeries();
            dmMinus = CreateDataSeries();

            maTr = Indicators.MovingAverage(tr, Period, MaType);
            maDmPlus = Indicators.MovingAverage(dmPlus, Period, MaType);
            maDmMinus = Indicators.MovingAverage(dmMinus, Period, MaType);
        }
