[BTC-TC] Virtual Community Exchange [CLOSED]

[burnside]

Nice catch, thank you!

Litecoin Global is also crying for a fix!

Edit:

I was wondering, when 2 orders have the same price, the older one gets filled first right?

LTC-GLOBAL should be fixed now too.  And yes, orders at the same price are filled FIFO.

Cheers.

I'm a little confused how this BTCgarden buyback works.  I go to my portfolio and I see an internal transfer box with BTCgarden in it.  Okay, now what?

You won't need to do anything.  Just wait - and when they do the buyback your shares will go and the BTC from the buyback will arrive in your account.

This.  Sit tight. 

Cheers.

Thanks，at least we aren't getting fucked over...

Burnside, would you please consider adding an email alert option for each btct.co and litecoinglobal login attempt/success?

BTC-e has this alert option, and I think it is really helpful to see if someone is trying to crack an account or verify a stolen password.

I do have 2FA, but the login email alert would give some much welcomed added comfort. I'd really appreciate your consideration!

Any ETA on the BTCGarden buyback?

Is the API broken? /api/tradeHistory/ has massive delays.

Is the API broken? /api/tradeHistory/ has massive delays.

AFAIK, there's a 10 minute cache.  How long of a delay are you seeing? 

If you want something a little quicker, you can pull from my feed here (I plan on making it a little prettier eventually):

http://coinflow.co/livetrades

There's an SSE stream at /livetradeevents/ which aggregates data from assbot and assetbot on IRC.   It's not the 'definitive' source since it isn't the API (I use API data in the charts for BTCTC, not assbot data), but it's still reliable.

Actually there was no delay till now.

Last trade @ /tradeHistory/ at unixtime 1376333707 (~34 minutes ago).

And /api/tradeHistory/LABCOIN for example stucks at 1376332899 (~49 minutes ago).

I kind of wonder what layers of caching there might be between you and us.  Any proxies you use?  Browser cache?  That sort of thing?

Cheers.

^ some minutes later.


Confirmed by two others. It's not a remote problem and I didn't change anything. No proxy, different browsers.

/api/tradeHistory/ slight delay
/api/tradeHistory/SYMBOL major delay
/api/tradeHistory/ticker slight delay*
/api/tradeHistory/ticker/SYMBOL seems to be okay
assbot in IRC has a major delay
/api/orders/SYMBOL seems to be okay
realtime ticker on btct.co is live

A slight delay is somewhere around 10 minutes, major delay over 30 minutes.

* /ticker had a delay of 1-3 minutes a few days ago, but anything else was live. All timespans are estimates.

I noticed the same things on the website. Orders were fullfilled but not yet listed in the history. That happened first around a week ago.
I can't tell if the API is also affected, but I guess both work on the same datasource.

Hi burnside,

I am worried about if all the users' Bitcoins of BTCT are stored safely. 
Are you store all users' Bitcoins in a cold wallet?
Will you use part of users' Bitcoins for other purpose?
Do you implement full reserve or partial reserve of users' Bitcoins?
Could you give out the cold and hot wallet BTC address? So we can check whether all the users' Bitcoins are there and not used for other purpose, and to let us know you are execute a "full reserve" for all users' bitcoins on your site.

Thanks

is there an easy way to input BTCT data into google docs?

like if i wanted the ask price from https://btct.co/api/ticker/COGNITIVE
how would i go about doing it?

I think I figured this out.  The purge of the cache on the trade histories for each trade wasn't always working.  There's caching a lot of places for a few minutes, but not purging was causing some caching to be as long as an hour on certain chunks of data.

Cheers.

Giving out the cold and hot wallet addresses is pointless because you have no idea what the sum total of everyone's deposits are and I have no way to prove it even if I told you...

I will however state that we do not run a fractional reserve, nor do we use the bitcoins on deposit for anything.  They just sit there.

Cheers.

can i get the BTC-TC trading app from website not from google?
pls assist

[dexX7]

kmtan: As far as I know the app doesn't work anymore.

Looks like everything works fine again. Thanks.

I have no malicious intention, but I did some brainstorming about orderbook manipulation. I noticed that larger buys/sells spread over a few orders take some time to get executed and actually it looks like as if those orders are filled one by one. Let's say I'd stuff the orderbook with a massive amount of smallish orders and a buyer/seller would initiate a buy/sell which would fill all those orders. Would it be possible to remove the later orders before they get filled after that order would have been initiated or is the book locked in that moment? Would the first fill of the bait-orders be propagated through the API before all of them are filled?

Would it be possible to remove the later orders before they get filled after that order has been initiated or is the book locked in that moment?

It sounds like that would require some really precision timing to work right, which I doubt is possible.

However, if you want to maximize your ability to buy through orderbook manipulation, then generating a large number of small orders is the way to go.  When you have insufficient balance, BTCTC will cancel your orders up to the point where you have sufficient balance to cover them on any one specific stock.  So, let's say you place an order on two stocks that have an identical price, stock A and stock B...  with stock A you have 20 bid orders of 10 stocks each, and with stock B you have 2 bid orders of 100 stocks each.   You make a trade on stock C which drops your available balance.   On stock A, the first 2 orders are cancelled, leaving you with 18 bid orders of 10 stocks each, and on stock B your first bid order of 100 is cancelled, leaving you with a single bid order of 100 stocks.   With a larger number of smaller orders, the cancellation leaves more order volume in place.
