Ok, I’ll take your word for the ‘whatif’ aspect.

?

If I use the contract parameters you specify in my platform, it works fine. If it doesn’t work for you, you must get an error message (assuming your request is actually being actioned by the API). So what is the error message?

?

I don’t normally use FDXM but I just pushed an order through on the paper trading system and it executed immediately. For what it’s worth, here’s the log entry that shows the order API message (I have my own API implementation that can log all API messages, similar to the TWS API logfile but rather easier to use). It may not be much use to you in this context:

And here’s the resulting execution:
