Did it affect your ATS? If not, ignore it. Change to include PUF woud not produce that error. It is related to market data flow.

Thanks - we will watch it and see how the next order reacts. If its just the data flow no problem if it affects are order entry..... Well that will be a problem then.



We will keep you informed - thanks for the info
