Maximum Allowed Trade Size for CFDs via API

Hello @Team212

I have a question about CFDs and your API (accessed via ProQuant). What is the maximum allowed “trade size”? Is the size restricted for the account? Or per trade/index/commodity/index/stock etc?

Does the error below imply I have to many open trades in my account? Or that the amount of cash per trade has reached its maximum?

I just need a bit more details on what the error is and how I can fix it.
Thanks

Edit:

I think Trading212 just released the reason for this:
