The Daily Quest can often take the shape of "Complete 2x International Trade".
Unfortunately, this can be a roadblock in getting all five Daily Quests simply because the minimum time for an International Trade is 1 hour.
To shorten this, I often plan to have an international trade arrive just around the refresh mark. For me, this means my ship arrives at its destination around 1800h. Even if it arrived earlier and I pay a late sales tax, this strategy lets me finish this Daily Quest quicker than otherwise possible.
Have fun, ST
