If you offer for e.g. 30 days someone can borrow it for 5 days.

..and can close it at any moment anyway.

Sure, but have you ever seen a swap that was specifically taken for a single day WITH the countdown for being returned set to 24 hours? The swap is now already returned. So it was just like I had put in "1 day" as a period. Never seen this before.

Could be someone having only 1 day left on their position and cycling through loans.

Hey

I have played around a lot and tried to have then found some on the internet which partly also works well, but i've got a problem.

It's about the Api Bitfinex.com, and although I would like to retrieve via the Api the "last trade" or by trading.

Link: bitfinex.com/pages/api


In the method: GET, with api_path = "/ v1/symbols", it works.

But if I used something else it stops working.

Error: The remote server returned an error: (400) Bad Request.


sry for the english 

anybody can help me / us ?

Code:

VB.NET-Quellcode

    Dim payloadJson As String = MySerializer.Serialize(payLoadobject)

It usually helps to check with something like wireshark how your request actually looked like.

Well, no, then the loan would have its regular, full length displayed, and would have been closed and returned  at some point.

So, today I try logging in, it says my password is wrong. I try resetting the password, it says no such email. But I logged in with this email just yesterday. So I made a test account, and I can see no way for an email to be changed thru the interface. So even if I was hacked, I don't see how this is possible. Any ideas re: just what the hell is going on?

[Sukrim]

Send a mail to the support address (ideally from the email address you used for your account) asap and notify them. This is not the Bitfinex support forum...

Question about "Flash Return Rate". Is the rate fixed at the time of borrowing? Or, if I borrow for 2 days, and on the 2nd day the rate changes, I get the new rate that day?

[Sukrim]

It is never fixed, it is dynamic. I'm not 100% sure how in the end it is calculated, since interest is most likely calculated by the hour, I would guess they take the average of the FRRs of the last hour sampled by some timeslot, maybe every minute or second (or the one at the end of the hour?) and then start adding up.

If FRR crashes while you have loans out there, you're out of luck, on the other hand if demand rises and the FRR goes up, you are lucky and get better rates without doing anything.

Has anyone encounter withdrawal issue recently? I cannot withdraw ltc AGAIN! It happens almost every time I do a withdrawal recently! After clicking the confirmation link in the email, it displays a 'pending review' or 'processing' and there's NO button to cancel! Sometimes it'll lock the coins for more than a day and you cannot unlock them without contacting support! WTF! Can the bitfinex guys fix this thing by just adding a cancel button? At least give a button to cancel the withdraw rather than lock all the coins, I cannot sell or withdraw them and I already lost money because of that!!

Lets assume, some traders default on their loans, the loss being considerable amount that bitfinex alone cannot absorb it.

Who will bear the loss?


The Unfortunate Individual Lenders
 
If so, how will the lender know for certain that his loans were defaulted and not some other users?


Collective Lenders

Will the loss be divided to all active swaps of that asset class?

As lending is a blind act, one cannot chose which trader/ pair to allocate to, wouldn't that option be more fair and less damaging overall?

[Dalmar]

In most cases margin calls would simply prevent this. If margin calls can't prevent it, there must be something wrong with the wider market and a whole bunch of lenders/traders are affected. So, the collective scenario is more likely.

No, it should be the first case I hope, the individual affected lender

Delete this post if it's against the rules but does anyone have a Bitfinex referral code to share? I'm opening an account and would like the reduced trade fee benefit. Thank you.

Nevermind, I found one in someone's signature line. Thanks!

...With that said, all ideas are welcome to ensure that unused swaps are not used for manipulation. We could double charge the closing of unused swaps without using them (but it would penalize legitimate use as well). We could prevent closing unused swaps manually (ie you can only use your swaps in a margin position or let it expires until the end of its period). What else?

Or we can just wait for people to realize costs/benefits of manipulation has become too high.

Anyway thank you for your analysis and have a good day

The last time I checked, it was possible to move all of the funds from trading wallet (where one needs funds to borrow swaps) to deposit wallet (where one needs funds to lend swaps), even though there are still unused and not closed borrowed swaps. So, just block that.
It actually makes sense and is not "in a way" for regular system use. Thus, if one decided to trade, have funds in trading wallet and borrowed swaps, he then cannot move the corresponding (!!!) amount to deposit wallet, before closing those borrowed swaps (subject to 1 hour minimum).

Question to Bitfinex team:
Why the bid/ask prices on the order book are not shown in dollars and cents? Seems like a common sense.
This practically voids a very useful functionality of pre-filling the order, by clicking on the offer.
Example: the bid offer of $622.6 per BTC will not get filled when clicked on it and ordered, because in reality it is a 622.56 (it is just rounded on the order book to 622.6).
One has to use third party sites to see what the real bid/ask to place the exactly matching orders and this can be a hassle.

What was the rationale behind removing the cents? Can we have two decimals back?

There is a "plus or minus" button that you can use to zoom in or out of the orderbook.  It is useful to be able to see deeper into the orderbook.  The zoom applies to both Bid and Ask side at the same time.
