When sending many market orders shortly after eachother we learned that some will appear as cancelled (automatically). Examples in this thread: Market Price orders - effectiveness of execution (observation) - update 30.09
You can reproduce this issue and I perhaps there is a relation. Do the following.
Make transactions but do not sign yet. Numbers in red represent the amount of ALEX being swapped.
Then sign them all 100% failed
Is it just failing because the timestamp becomes invalid? I waited to long. How much time does a user have?
I think if that is the reason for the failed transaction it should be noted on the failed transaction. Now it looks the same as a manually cancelled transaction.
are there other reasons for failing automatically like this? can we add notes about that too?
