Cannot Serialise IOrder

[LloydH]

Hi

I am getting the following error when I try to enable my strategy

07/04/2010 14:48:26|0|4|Failed to execute DB job 'StrategyUpdateJob': There was an error reflecting type 'NinjaTrader.Strategy.CrossoverV10'.: There was an error reflecting field 'ShortOrd'.: There was an error reflecting type 'NinjaTrader.Strategy.CrossoverV10.Order'.: Cannot serialize member 'NinjaTrader.Strategy.CrossoverV10+Order.oe1' of type 'NinjaTrader.Cbi.IOrder', see inner exception for more details.: Cannot serialize member NinjaTrader.Strategy.CrossoverV10+Order.oe1 of type NinjaTrader.Cbi.IOrder because it is an interface.

I also have these messages in the trace file

2010-04-07 14:56:42:982 Db.Globals.StrategyUpdateJob2: WARNING: Execution='' Instrument='6E 06-10' Account='Sim101' Name='Virtual Entry Execution' Exchange=Default Price=1.335 Quantity=4 Market position=Short Commission=16 Order='-None-' Time='07/04/2010 14:02:50'

I noticed that this problem occurs if my strategy has active orders after loading the historical data on the chart (I am loading the minimum 1 days worth of history). I do NOT get this problem if my strategy is Flat after loading the historical data on the chart.

LloydH,

To check, what version of NT7 are you using? Can you provide us with steps we can follow to reproduce? Thank you.

[LloydH]

I have Version 7.0.0.13. I will post more details on how to re-create shortly.
regards
Lloyd

Lloyd,

In your strategy code did you make a public property for an IOrder? IOrder objects cannot be public properties so you will need to remove that. Please see if that helps.

Josh,

I have my IORder objects stored in a list which had public properties, changed to private and it has fixed the issue. Many Thanks,
Lloyd

Great. Glad you got it resolved.
