OP was trading below IB FXPRO minimum lot size. A convenience to IB customers for currency conversion. You are told when putting the currency conversion on not to expect an immediate fill even if you see your price trade through.
I cannot find the document on the IB website. Maybe it is only securities brokers that send the data to the OECD though IB is securities and commodities.
Interactive Brokers now support Wise and if you iniate the transfer to IB from IB account management then it is extremely quick. it is a way to get money to IB cheaply for small accounts.
