OCO ID Size Constraint

[reach4thelasers]

Hi there

Is there a formal size constraint on the OCO ID field? I would like to use the field to store data in MessagePack format encoded in Base64. I guess it's broker dependent I'm using FXCM but can't find any info.

I've written a bettter managed order handler but it loses track of the orders it's managing every time I rebuild or restart Ninjatrader so want to pack data into the OCO ID field so that I can rehydrate the order manager and allow it to continue to manage its orders after a restart or rebuild.

Thank you

Kevin

Hello Kevin, and thank you for your question. While there are no formal documented limits on OCO IDs in Ninja, strings in C# can generally only have 2^31 characters. This publicly available stack overflow discussion has more information.

Ok thanks Jessica. I will try some big values to see how much I can put in - I definitely wouldn't be needing 2 Billion Characters - probably 100bytes. I guess the order gets stored on the brokers database somewhere so I expect it will be constrained in some way.

Thanks for your response.

Hey Jessica

I was able to serialise the data I needed into the field however FXCM didn't return it when I restarted Ninjatrader- I guess it was too long.

Is there anywhere internal to Ninjatrader that I can store some data?

Thanks
