Thanks! We need no report of further "No Datas" at this point, as we know this problem already. But as to under which conditions it happens more often or less often, my guess is as good as yours.

The problem is unrelated to the internet connection, but it is seems to be affected by something else, because it happens much more frequently on some user's machines than on others. Maybe it's the RAM size, which would explain why we never observed this problem here with version 1.12.

The message "Cannot place more than one order of this type for each trade" was wrong. Zorro does never place several orders per trade. The real reason of the problem was no quotes at that time, so the trades could not be closed. Zorro retries until the trade is closed.
