OnMarketData Printing some strange sign

[swcooke]

Given this bit of code, I am getting a strange value printing to the Output window. Attached is a screenshot. Here is the code:

        protected override void OnMarketData(MarketDataEventArgs e)
        {
                double price = (e.Bid + e.Ask)/2;                
                Print(price);    

        }

Hello swcooke,
Thanks for your post.

I am looking into this and will let you know when I have further information.

Here is what I came up with. Let me know what you think:

        // Tests a Double for Nan or Infinity
        public static bool IsNanOrInfinity(double value)
        {
            return !Double.IsNaN(value) && !Double.IsInfinity(value);
        } 
     protected override void OnMarketData(MarketDataEventArgs e)     {             double price = (e.Bid + e.Ask)/2;             if(!IsNanOrInfinity(price))return;                             Print(price);         }

swcooke,

This is expected to occur because those market data objects will not always have a value. It would be recommended to wrap you logic up in a wrapper similar to how it is done in the sample here: https://ninjatrader.com/support/help...aeventargs.htm
