Hard to explain, easy to show...

(1hr chart) - Tescode below. It relates to how a cbot initializes past data for an instance of an indicator used in the bor.

1. Log output (with Period paramter = 50): 

#####################################
01/11/2018 11:00:00.000 | Backtesting started
01/11/2018 12:00:00.000 | sma: prev: 1.1346988 last: 1.1346042 isRising? False | isFalling? True
...

NO NaNs - all good up to a period of 125

2. Log output (with Period paramter = 200):

#####################################
01/11/2018 11:00:00.000 | Backtesting started

Is the best answer to solve this is to just run the bot on a higher time frame as it only populates 125 Periods of past data when the cbot starts?

Thank you.

The test code just for reference:

        public double Parameter { get; set; }

        [Parameter("SMA's Period", DefaultValue = 4800, MaxValue = 9600, MinValue = 24, Step = 24)]
        public int smaPeriod { get; set; }

        [Parameter()]
        public DataSeries Source { get; set; }

        private SimpleMovingAverage sma;

        protected override void OnStart()
        {
            // Put your initialization logic here

            sma = Indicators.SimpleMovingAverage(Source, smaPeriod);

        }

        protected override void OnBar()
        {

            Print("sma: prev: {0} last: {1} isRising? {2} | isFalling? {3}", sma.Result.Last(1), sma.Result.LastValue, sma.Result.IsRising(), sma.Result.IsFalling());
        }

        protected override void OnStop()
