Thanks for the OCO orders.
very much appreciated.

One detail question: Is there some kind of headroom added to the current ticker price?

E.g., currently the lowest ask is at 619, highest bid 618

Now, if I want to open a long position and thus enter limit = 614, stop = 620, I get a error popup "OCO stop rate is below ticker". The lowest stop value accepted by the system is 627, which seems quite off the current spread IMHO.
