TimeSeriesMovingAverage and historic data problem

When using a TimeSeriesMovingAverage on an hourly dataseries, it returns Nan for several days until enough data is collected, however something like ExponentialMovingAverage works straight away

Does anyone know of a workaround for this issue?

Code example:

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

namespace cAlgo
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class NewcBot : Robot
    {
        public ExponentialMovingAverage ema;
        public TimeSeriesMovingAverage tsma;
        public RelativeStrengthIndex RSI;
        private MarketSeries time;

        private int min;

        public bool CalcTime()
        {
            bool result = false;
            if (min != Server.Time.Minute)
            {
                result = true;
                min = Server.Time.Minute;
            }
            return (result);
        }

        protected override void OnStart()
        {
            time = MarketData.GetSeries(Symbol, TimeFrame.Hour);

            RSI = Indicators.RelativeStrengthIndex(time.Close, 14);
            ema = Indicators.ExponentialMovingAverage(RSI.Result, 200);
            tsma = Indicators.TimeSeriesMovingAverage(RSI.Result, 200);

        }

        protected override void OnBar()
        {
            if (CalcTime())
            {
                Print("tsma: " + tsma.Result.Last(0));
                Print("ema: " + ema.Result.Last(0));
            }
        }

    }
}
