All my OPG orders have been rejected the last three days. Actually, when hitting "transmit" nothing happens. No error messages, etc. I use the API to generate the orders, but submit manually from TWS
thank you very much. I use SMART, too, even though I did try NYSE on friday, just in case. I guess I'll reinstall TWS and the API and see if that helps. If I figure out what caused it, I'll post here
