Error reflecting property 'MarketDataUpdate'

[kenconcannon]

I am getting an error when running a strategy.

The strategy is actually broken into a base strategy:

public abstract class TradeBase : Strategy, INotifyPropertyChanged

... and a strategy calling the base....

public class StrategyExample : TradeBase

Everything works fine (I have been using this for months). I tried to add a secondary data series to the base (same instrument, different time frame) and when I try to execute I get the following error:


There was an error reflecting type 'NinjaTrader.NinjaScript.Strategies.xxxxxxxx'. ---> System.InvalidOperationException: There was an error reflecting property 'MarketDataUpdate'. ---> System.InvalidOperationException: There was an error reflecting type 'NinjaTrader.Data.MarketDataEventArgs'. ---> System.InvalidOperationException: There was an error reflecting property 'Instrument'. ---> System.InvalidOperationException: There was an error reflecting type 'NinjaTrader.Cbi.Instrument'. ---> System.InvalidOperationException: Cannot serialize member 'NinjaTrader.Cbi.Instrument.HistoricalData' of type 'NinjaTrader.Data.BarsBytes[]

Do all the data series need to be defined in StrategyExample or is there another way to address this?

Hello kenconcannon,

Custom inheritance is not supported in NinjaScript so that is not something we can assist with. While you can use that C# feature it may cause problems with various parts of the platform. We suggest to only use the standard inheritance that the platform creates such as public class MyStrategy : Strategy
