I have been working all weekend on upgrading the server to a faster platform. It’s not ready yet (schedule to be announced soon).
Alas, this may be responsible for some strange fills this morning (Monday February 23). If your system has filled incorrectly, please email me. Be sure to include your system name, and which stock/future/option filled incorrectly. Please tell me the price it filled on Collective2, and where you think it should have filled.
Sorry for the trouble. We’ll figure this out. I will report progress here.
