Just wanted to bring this up to the attention of Bitfinex team:
Here is the screenshot of the "unused swaps" section (part of it):
http://imgur.com/8Ias0ncThe swaps supposed to be at least two days long, but as seen in the picture above, there is freshly taken swap with the 24 hours (instead of 2 days) expiration time. This snapshot is taken from the "unused swaps" section, right after they have been taken from offers order book (today). This is not an isolated case, I have seen this happening several times and so far I could not deduct any patterns of this occurrence.
Moreover, several times now I've seen swaps showing 2 days expiration date, in spite of the fact that the offer taken (a single one listed) stated that it is a swap with different than 2 days duration.
With that said, I do not know if these "shortened" swaps are going in with the same (shortened) expiration time when converted to "active". It is hard to trace them on the list.
On a separate note I just wanted to share that the possible reason for all those "under penny" swaps people are complaining about being listed and cluttering the section, is because swap request placement is done in 2 decimals after the point if user clicks on available offer (it is actually impossible to know the exact number of any given offer while it is on the order book). SO, if such offer has more digits after the second decimal, it gets spit and the under penny part apparently remains hanging on the order book and is somehow getting on the list (possibly if new swap request is placed immediately). Those traders who do this often (picking offers from order book by clicking on them), will have a hole load of these small (under penny) swaps.
It also looks like you cannot get rid of these tiny swaps because if you select them all (sort the list by the "Amount" column) and cancel, they will all come right back one for one. HOWEVER, what I found is that this "one for one" replacement ONLY happens if you have any swaps already sitting in your "unused swaps" section.
I was able to get rid of them all at once and replaced by a single (sum of them) swap, when I had no swaps reserved (nothing in the "unused swaps section). I guess this is how the system is set up and after I cancelled a bunch of swaps without having any reserved, it did not look for the swaps I just cancelled, but simply took one new swap from the order book to match the total needed for my position. So, apparently the difference here from system's perspective is that you are either
REPLACING the swaps or you
HAVE TO take brand new swap to match your total needed for your margin position.
Probably what can be done/modified technically in this respect is to have the system completely ignore the number and amounts of swaps user is canceling, but always "look" for how much total is needed as the collateral for currently existing position and start looking for this particular amount
first in the "unused swaps" section and then, if not enough, get the remainder from swaps order book.
So, no support? I thought there was a new person on support team...
All of the above is valid and swaps with 1 day (instead of the 2 minimum) do go into list as is, when they are becoming active.
