Strategy Analyzer Error

[tamas]

Hello,

At my end it can be reproduced:
- Save results of optimizer.

That actually is 2 issues:
a) NT definitely should not throw an exception. We'll look into.
b) However, the underlying issue that your strategy could not be saved since it's not XML serializable. XML serialization is a standard C# technology which is documented in the MS docs. There also should be a couple of threads related on that forum for further guidance.

Dierk,

pls check sample file, if uncomment property, it will throw error.

Correct. These are limitations which I had been referring to.
