Topic: Announcing bitcoin-central.net - trade USD and EUR for free! - page 5. (Read 17713 times)

Right now I haven't really thought about all that.
But maybe you can give some advice about how it should go ?

Please bear with me while I'm hard at work polishing rough edges, crossing some t's and ensuring that everything is rock solid

Would you consider cash in mail in order to put in some funds ?

Would you consider ACH in/out of bitcoin-central for large volumes like MtGox?

I don't mind opening some parts up.
I basically have a wrapper for the client that's based on method missing and making use of a nice yml file for credentials, ports etc.


Is an example use case.

Then I have a whenever schedule that feeds the transactions into my DB, updating confirmations every couple of minutes.

Nothing very complicated, i'll share it if you find some use to it, but right now all my time goes to smoothing trading out

Maybe you could open source the payment processing code part. I am a rails developer too, but I am kinda lazy about learning the payment processing part.

In my private repos

Idk, never really thought about it but it represents quite some man hours

My pleasure, I hadn't found such an exciting rails project since a long time, also all the cool kids have opened their BTC service

mtgox has:
    * http://mtgox.com/code/ticker.php
    * http://mtgox.com/code/data/getTrades.php

bitcoinmarket has the previously mentioned real-time API, and also
    * https://www.bitcoinmarket.com/bitcoin/fxchange.quote.json
    * https://www.bitcoinmarket.com/bitcoin/fxchange.quote.json.alt
    * https://www.bitcoinmarket.com/quotes/offers/bids/
    * https://www.bitcoinmarket.com/quotes/offers/asks/
    * https://www.bitcoinmarket.com/quotes/trades/

The ideal ticker would have, for each currency pair
* currency pair
* last-traded price
* last-traded datetime
* volume, last 24h
* highest bid
* lowest ask
* open price, set once every 24h at "beginning of the day" (== midnight UTC, probably, if you are open 24/7)
* previous close price (might be same as open price, if you are 24h and have no dark pools etc.)
* highest price since "beginning of the day"
* lowest price of "beginning of the day"

The first six are provided by all markets and are IMHO "required."

Trade data is generally
* currency pair
* price
* datetime
* quantity traded

but feel free to include anything else that does not compromise the privacy of your users.

Returning data in JSON format seems to be de facto bitcoin community consensus (only BCM is an outlier here, and only for their trade data; BCM's tickers are JSON).



Not sure how to parse that... is your exchange's source code published at github?

If not, what's your price for open sourcing?  

Thanks for opening another exchange!  bitcoin needs more competition in this area.

I see, I'll start adding more of these once I've ironed the first quirks out, I love Ruby on Rails and it's "if your test suite is strong, go nuts with refactoring"

Sure, just give me a couple examples so I can just mirror some API you're already being fed.

I'll look into that, it has its official github issue

Yea, I'm thinking that it could be really nice

Not as much as LRUSD, but there is a consistent level of demand.  It's useful because, just like bitcoin, PGAU is not a fiat currency tied to a nation-state.  And it's easy to implement in an automated fashion, once you support LR.

GlobalDigitalPay is another easy one to support; GDP's API works like LR's API.  GDP supports USD, EUR and GBP.

Additionally, with my bitcoinwatch hat on, please publish

• current "ticker" in JSON, showing last-traded price, current bid, current ask, volume for past 24 hours, etc.
• full data for each trade, in JSON format

And something like bitcoinmarket's real-time data service would be nice.  I wrote some Perl to accomplish this, see
http://yyz.us/bitcoin/bcast-README.txt
http://yyz.us/bitcoin/bcast-server.txt
http://yyz.us/bitcoin/bcast.txt

or simply "telnet www.bitcoinmarket.com 27007" and add/remove a bid or ask on BCM to watch the real-time data stream.

P.S.  If you wanted to see your site's popularity skyrocket, permit trading between non-bitcoin currencies, such as GDP-USD / LR-USD, or GDP-EUR / LR-USD, or LR-USD / Pecunix GAU.

That is because the seller/buyer doesn't have enough balance to complete the trade, this is an issue, I will fix it promptly

I raised the bar a little to 3 confirmations which was the original setting, do you like the "your funds are here, just wait for it a little more" instead of "F5, not yet, F5, not yet, F5, phew, finally". You can hover over the amount in the account history to see how much more confirmations are required.

Fixed, thanks for bringing that to my attention

Thank you very much!

Fixed, it now gently redirects

Is there really that much demand for it ?

See previous answer, I'm going to fix this ASAP, it is confusing indeed, I'll inactivate orders when they fail to complete due to lack of funds and try to reactivate them after each successful incoming transfer.

You got the "server error, something went wrong, i'll eat your family" page ?
I'll check the logs and try to reproduce, thanks for pointing it out.

Yea, I know
I want to start supportign LiqPay, that would also allow total noobs to buy with a plain old CC. But I'm afraid that would be against their ToS and that I'd end up gang raped by angry users if my account gets frozen. I'll see when I've ironed the rest out.

Maybe they got caught for not complying with banking regulations or sthg? I guess it wouldn't be too risky if I always maintain a <2~3k€ balance on the bank account.
You can donate by bank transfer though :p

I'll deploy the fixes in an hour or so.

Thank you very very much for your comments and positive feedback !!

Same here, I got a partial fill then cancelled the remaining fragment.  I then tried variations to try to prod the trade, e.g., offering to sell below the bid, amounts smaller than the remaining buy size, etc.,

Adding BTC went very  well ..., appeared that I could use them to trade after just 2 confirmations.  Withdrawing in both LRUSD and BTC went smoothly.

Wish I could see the order book without authenticating first though.   Even if just a best bid / best ask.

Happy to see this exchange though and will likely use again!  Acknowledged the donation afterwards.  Good stuff!

+1 good stuff

Suggestions:

• Connecting to non-SSL http://www.bitcoin-central.net/ gives an unfriendly "access refused" message
• Supporting Pecunix GAU would be nice

I don't get it.  There are matched entries under Selling and Buying, but no trade happens.  I also got an error message when trying to buy, but the bid goes in.

+1

Any chances of sending euros through bank transfer, like bitcoinexchange used to do? (By the way, anyone knows why they are gone?)

Excellent.  There's still the problem how to buy LR though.

Yes, that's right, some extra competition in the bitcoin trading field!
