Thanks!

Now I'm probably too picky, but why the 30 day max limit? I'd like to calculate earnings from the beginning of the year. I don't think it will be too cpu intensive.

I'd also be happy to use just an approximate daily average rate (and have a tiny bit of error) if that'd be easier to do and allow for a longer date range.

Well, I took the max period Bitfinex is allowing atm. I can increase it, have to check how much cpu it takes. but I might

You could fetch the historical results once and store them in a database (or even a flat file).

BTC trader is a ponzi. And it is off topic.

A past flexible swap interest calculator would be nice. What is the cumulative interest for a specified time period? This is useful because the interest rate can spike - so averaging it out would be useful.

For instance, I'd like to be able to calculate what interest rate I earned since the beginning of the month.

Just added it

TY Derek. I myself talked to BFX owner Raphael quite a lot and therefore I am sure they are not scam. BFX has been the most reliable BitCoin Exchange I ever witnessed, even if compared to the uber-trustworthy bitcoin.de or very liquid bitcoin24 (who are long done).

So I value your insight about BitCoin Trader a lot, thanks mate. (if there are too many referral links in this text for your taste, you are probably correct =oP)

Thanks for the tip on btc trader. Are they Trustworthy.

Depends who you ask. I've used them for about 5 months now and they have made every payment (every weekday except for bank holidays) and at the end of each 120 day term I have received my principle back. The website is clean and looks good. Their customer service is prompt and they have a facebook group in which several of the employees respond to questions and comments daily. They have also sponsored multiple major bitcoin conferences and are currently part of a cross-country (USA only) promotional tour. They are also planning to undergo and audit near the end of August, carried out by a London accounting firm (the CEO is based out of London). So yes, I think they are trustworthy.

If you look around the forums, you will see a lot of people calling them a HYIP scam, but in my opinion, most of these people have not actually investigated the website too closely and think the daily return is too good to be true or they are trying to promote some other competing website.

If you have any other questions feel free to PM me. I feel like I shouldn't be clogging up this thread.

USD Swap rate really low now. You guys think it will go up again?

Yes, but not till the price starts going up. Even if the price crashes the swap rate will go up while the price is recovering. I do think in the long term the rate will continue to go down as more people with money use the site as even 0.1%/day is absurdly good by most standards (~44% APR if compounded daily). At this rate you could even take out a bank loan and loan it out and still make a profit. That said, while the price is going down I'm putting some cash in bitcoin-trader https://bitcoin-trader.biz/?ref=dhorks since they've been paying ~0.8%/day lately.

Would be awesome to somehow have an option to filter graphs by duration i.e. if i want to borrow on a 30day term i could care less how many millions are offered on 2day terms and want to see 30day demand/offers graph. Right now i have to manually scroll through pages of USD swap offers to manually spot one for 30 days

I'm actually working on this. I'm adding a feature where the user can select a period (2d <> 30d) and the swaps stats page will display all tables and charts for the selected period.

Hi, it seams to be a wrong link in header menu

Swap + Price Charts > LTC

redirects to /combined/btc.php instead of ltc.php

you're right! thanks for pointing that out.

New menu system doesn't work for me in Firefox. Click on menu - get list of top level menu options. Click on one of them - nothing happens.

Also - I liked the old USD swap view - notably the chart of outstanding USD swaps (and FRR) vs time. That's my favorite chart!

Menu should be working now. You do know that the old pages are all still available, right? just browse the menu and you'll find them.

thanks for your bug report.

Wow great. I'm working on (made my own Python API lib) Bitfinex API for several day, especially to monitor swaps. Estimate earning, alert when something is wrong, alert when a swap lending will finish...

Seeing your new page, I noticed mismatch between your web interface and records I get from "Lends" API: https://api.bitfinex.com/v1/lends/usd

Quote

Lends
GET /lends/:currency
Get a list of the most recent swaps data for the given currency: total amount lent and Flash Return Rate (in % by 365 days) over time.
Response
An array of dictionaries
rate (decimal, % by 365 days): Average rate of total swaps opened at fixed rates
amount_lent (decimal): Total amount of open swaps in the given currency
timestamp (time)

That gives:

Quote

Latest Lend Rate:
Rate , Amount, Date
0.1657% , 30299688.26 , 14:23:29 09/Jul/2014
0.1657% , 30284681.40 , 13:23:36 09/Jul/2014
0.1658% , 29756298.65 , 12:23:44 09/Jul/2014
0.1659% , 29753105.97 , 11:23:51 09/Jul/2014
0.1659% , 29699328.50 , 10:23:37 09/Jul/2014
0.1659% , 29699910.93 , 09:23:48 09/Jul/2014
0.1659% , 29751029.92 , 08:23:32 09/Jul/2014
0.1660% , 29696461.29 , 07:23:44 09/Jul/2014
0.1659% , 29677436.69 , 06:23:33 09/Jul/2014

Then I understand why you state : "Big thanks to the Bitfinex team for providing me with the swap transaction data!" Wink

So great job, very useful for me. They just share publicly "aggregate mean" data for lending. Additionally to show data in a clear way, your website gets data that we cannot normally get Wink

Congratulations!

Those who ask for price monitoring, you can have a look at bitcoinwisdom.com

Hi all,

Just like to share a little update on bfxdata.com. I have just finished a little project I've been working on. I've added 3 new pages to bfxdata.com: Live Swaps for USD, BTC and LTC. The new pages wil give you a real-time view on bitfinex Swaps. So no more highest demand / lowest offer as an indicator of what the current Swap rates might be, but charts based on actual Swap transactions taking place between swap provider and margin trader. Just check out the pages and I think it will be more or less self explanatory when you see them. If not, do let me know. Big thanks to the Bitfinex team for providing me with the swap transaction data!

regards Bjorn

Some people see a price gap as evidence of a problem at one of the exchanges. This was definitely true of MtGox and the withdrawal delays which ended up in bankruptcy.

If the price gap is more than 1-2% and persists in a regular (non-bull) market - then it is evidence that something is wrong as arbitragers should be able to decrease the gap to that level.

Some people (on the forum and reddit) have been guessing that Bitstamp is having problems - but so far there isn't solid evidence.

I'd give this more priority if the price gap becomes an issue in the future.

Tracking the Bitfinex BTC price difference vs Bitstamp would be nice. Though possibly too much work as it would involve a second API (and more of a matter for sites like Bitcoinwisdom).

Most of the time it settles down to a couple dollar difference, but over a week ago there was a $20-$30 premium that lasted for at least a day.

well the multiple api thing isn't much of a problem, but what information will it give us ? What does a price difference between stamp and finex represent? Personally I can't really tell. Differences started after finex stopped routing orders to bitstamp and afterwards we saw a similar price difference we were used to with btc-e vs stamp but now between stamp and finex. So if someone can give me a good explanation of why the price differences between exchanges over time (I can add btc-e in the mix as well) is useful, I will start tracking it (arbitrage?) Well, give me your thoughts and convince me and I'll add it to bfxdata
