System.Threading.Thread cannot be serialized because it does not have a parameterless

[Evggne]

Hello!

When I start strategy I getting this error. Just in the process of strategy get this error.

Default,Failed to execute DB job 'StrategyUpdateJob': There was an error reflecting type 'NinjaTrader.Strategy.Bot'.: Cannot serialize member 'NinjaTrader.Strategy.Bot.t1' of type 'System.Threading.Thread', see inner exception for more details.: System.Threading.Thread cannot be serialized because it does not have a parameterless constructor.,

Evggne,

Thank you for your post.

Are you adding any thread properties through the strategy?

If so you may need to add [XmlIgnore()] attribute before it so it does not go into serialization.

That's part of the code. XML do not use.


// This namespace holds all strategies and is required. Do not change it.
namespace NinjaTrader.Strategy
{
/// <summary>
/// Enter the description of your strategy here
/// </summary>
[Description("Enter the description of your strategy here")]

Evggne,

Try using a private variable instead of a public -
private Thread t1;

Does this solve the error?

[Evggne]

Yes, the problem is solved. Thank you very much!
