Failed to Submit Orders - System.NullReferenceException.

[rajesh00074]

I am getting an error while submitting an order. Entries are fine but this error comes when I issue a stopmarket order at everybar low or high as trailing. I tried many suggestions given in the forum but not able to resolve. I also tried some of the samples provided which also shows this error. I am a C# programmer and have made sure I am not using any objects that is null or not initialized. I am using Ninjaversion 8.1.1.1 64 Bit. I am running this strategy in a renko chart. Can you provide any insights to resolved this ?

Thank you. Finally I figured out that I had applied ATMStrategyIdentifier (downloaded from Ninjatraderecosystem.com) as an indicator which was throwing the exception. Thanks for sharing the inputs which helped in identifying the issue
