101  Economy / Trading Discussion / Re: Can somebody explain an order book to me? on: September 21, 2014, 09:44:20 PM
The x-axis shows the price. The y-axis shows the depth of the orders. And the colours show the order types, i.e., either buy or sell. So, if you look at 0.00013 and see that there is a green volume corresponding to 1 in the y-axis, it means that there are buy orders at 0.00013, the total volume of which is 1 BTC.

Also, be warned that the order book in the OP is in log scale. http://www.khanacademy.org/math/algebra2/logarithms-tutorial/logarithmic-scale-patterns/v/logarithmic-scale
102  Economy / Trading Discussion / What is the best exchange for algorithmic trading? on: September 21, 2014, 09:38:56 PM
Hi,

I've been working on a blackbox trading engine for a while. It actually yields quite a lot of profit and everything is perfect, except for the exchange BTC-e. Their API simply sucks. They block API keys for no reason. Sometimes the server cancels a given order immediately after it's given. Their customer support also sucks. I asked their technical team about the problem, showing my code and telling about what happened. All they said was that the code seems OK.

So, I am in search of a bitcoin exchange with a reliable trading API. Any advice?

PS. Liquidity is also a concern since I am planning to play big in the near future. So it must also be one of the biggest exchanges.

Bankacılık Düzenleme ve Denetleme Kurulu'ndan elektronik para kuruluşu olarak akredite olması için tüzel kişiliğinizin anonim şirket olması şartı vardır (Resmi Gazete, madde 18, 3. fıkra, c bendi). BTCTurk ise kendi Kullanım Sözleşmesi'nde açıkça kendini Bitcoin Trading Ltd. Şti. olarak taraf kılar. Bu da yaptığı işin yasalarca korunmadığını, bir gün BTCTurk'ün hesabına devlet tarafından el koyulabileceğini ve bu durumda bütün kullanıcıların madur olabileceğini gösterir.

Ciddi yatırımcıların BTCTurk'ü seçmeleri için BTCTurk'ün bu konuda herkesi aydınlatması, biz kullanıcıları maduriyet korkusundan kurtarması gerekir.

BTCTurk Kibrista Turkiyede degil.
Yurtdışında açılmış elektronik para ve ödeme kuruluşlarının Türkiye'de faaliyet göstermesi için gene BDDK'nın izni gereklidir. Ayrıca BTCTurk'e bakiye eklemek için para yatırılan hesap Türkiye İş Bankası olduğundan, bu hesabın denetimi gene BDDK tarafından yapılır.

105  Economy / Trading Discussion / Re: Gekko - a javascript trading bot and backtesting platform on: July 05, 2014, 09:08:18 AM
kuzetsa,

Thank you very much! I don't use softwares with lack of developmental support. I didn't know the original author stopped the support. So that means the end of Gekko for me, until maybe one day I want to involve in supporting it. I already have a code running, collecting data and executing orders, but I thought immigrating to Gekko might serve better for future interests.

I use 2 hourly intervals, and RSI(14) needs somewhat 250 candles, which makes about 20 days for a reliable signal.
106  Economy / Trading Discussion / Re: Gekko - a javascript trading bot and backtesting platform on: July 04, 2014, 09:01:20 PM
Hi!

I don't want to wait for 20 days to have a reliable signal from RSI indicator, so how can I add the historical data on top of the data collected by the bot in its runtime?

Bitcoincharts.com has the historical data, and it's easy to put them in the form of {"s":1239,"o":628.372,"h":628.372,"l":628.372,"c":628.372,"v":0.033,"p":628.372,"_id":"plNRczdJWMI7ds5V"}, but what's "s", can it be negative? And what's _id? And I guess p is the adjusted price. Is it vwap?

Thank you very much in advance
107  Economy / Service Discussion / BTC-e API cancels orders on: July 04, 2014, 03:29:05 PM
Hi,

BTC-e API doesn't show open orders, instead it cancels them. Code is below:

Code:
$BTCeAPI = new BTCeAPI ($apikey, $apisecret);
try {
$getInfo = $BTCeAPI -> apiQuery ('getInfo');
} catch (BTCeAPIFailureException $exception) {
echo $exception -> getMessage() . '<br/><br/>';
}
if ($getInfo['success']) {
if ($getInfo['return']['open_orders']) {
$params = array ('pair' => 'btc_usd');
try {
$orders = $BTCeAPI -> apiQuery ('ActiveOrders', $params)['return'];
} catch (BTCeAPIException $exception) {
echo $exception -> getMessage() . '<br/><br/>';
}
foreach ($orders as $key => $value) {
echo "Open order: " . $orders[$key]['type'] . ' ' .
$orders[$key]['amount'] . ' BTC @ ' . $orders[$key]['rate'] .
' USD<br/><br/>';
}
}
$balanceUSD = number_format ($getInfo['return']['funds']['usd'], 2);
$balanceBTC = number_format ($getInfo['return']['funds']['btc'], 2);
$timestring = gmdate ('Y, j M H:i (e)', $getInfo['return']['server_time']);
echo 'Balance: ' . $balanceUSD . ' USD + ' . $balanceBTC . ' BTC @ ' . $timestring;
}

Anybody has an idea where is the mistake?

It seems somebody finally understands the problem. Thanks, HostFat.
109  Bitcoin / Development & Technical Discussion / Re: Alternatives to blockchain technology on: July 01, 2014, 01:43:15 AM
gmaxwell,

Maybe you've not read it. Huh?

Well, forgive my arrogance. By "history" I don't mean all the transaction data. History of a bitcoin is stored in a compressed form, omitting the earliest transactions, in each node. But what is stored is still the history of each and every satoshi. Am I wrong? I mean, in the end, a blockchain cannot be history-blind.

My question was whether there is someone who is working on a history-blind trust-free transaction validation network.

"01.07.14 03:20 Your deposit 0.0101 BTC successfully credited."

Thank you very much, whoever you are, my silent helper! I will send 0.02 BTC back ASAP : )
111  Economy / Lending / Re: I urgently need 0.01 BTC on: July 01, 2014, 12:29:18 AM
Maybe not from you, byt411, but you will not forbid that, right? I insist, and believe that somebody will lend me that 0.01 BTC. It was so kind of you that you posted a reply even if your response was negative. You may have just silently not sent. I couldn't describe how I feel happy to interact with such kind people.

Just 6 hours for me to get my own coins. So, be quick! You wouldn't want to miss helping me.
112  Bitcoin / Development & Technical Discussion / Re: Alternatives to blockchain technology on: July 01, 2014, 12:20:22 AM
Well, let's fix it, then. Blockchain is based on the public distribution of the transaction history of each and every satoshi. That transaction history may be compressed by some methods, but this doesn't change the fact that each and every satoshi has a history stored in each and every working node.
113  Bitcoin / Development & Technical Discussion / Re: Alternatives to blockchain technology on: June 30, 2014, 11:53:35 PM
I have indeed read §7. I am thinking of a technology other than chaining blocks. Actually, I am thinking of someone who thinks of it. Is there any one of the kind?
114  Economy / Lending / Re: I urgently need 0.01 BTC on: June 30, 2014, 11:38:00 PM
Dear Brad Pitt of Crypto,

Thank you for sharing your extraordinary feelings. I don't want anybody's bitcoins who thinks I need a collateral for 0.01 BTC. Kill your idols!
115  Economy / Lending / Re: I urgently need 0.01 BTC on: June 30, 2014, 08:45:56 PM
It's just that I don't want to wait. Not a big deal. Thanks, though.

The word "urgent" is also quite suspicious, can't bot development wait a bit?
LoL! Thanks for your contributions.

Or, you could try running the bot in a sort of sandbox where actual market prices are used to determine what happens to a virtual balance you use for testing. There's no real reason for this loan.
You know a lot, don't you? I don't worry about my balance. I only want to test the API integration. For instance, I want to see what the API actually returns when I want to see my active orders. I cannot have an active order without a balance, can I?

For God's sake, you are aware that 0.01 BTC is worth less than $10, and will be so at least for a couple of months, right?
116  Bitcoin / Development & Technical Discussion / Alternatives to blockchain technology on: June 30, 2014, 08:41:53 PM
Hi fellows,

Everybody knows that the blockchain technology has solved a big issue, having its own drawbacks and failures, most of which have been being solved but many of which are essential handicaps of the technology behind cryptocurrencies. One of those handicaps is the blockchain size. Blockchain has to include each and every transactions made in the network so that each satoshi has a recorded history. This may be contrasted to paper money since banknotes are essentially history-agnostic.

My question is whether there is a developer working on a different trust-free transaction validation network proposal.

All existing wallets having a positive balance and their holdings may be stored, for example, instead of storing all transactions. Is something like that or something other than that doable?

117  Economy / Lending / I urgently need 0.01 BTC on: June 30, 2014, 07:53:01 PM
Hi there,

I have been developing a trade bot for BTC-e exchange. Everything was about to come to an end until I realised that I have no coins left on my account. Can someone please send me 0.01 BTC at 1ATASiLrj4VyNAHci5Z12zg7mHQPMnxh69 so that I can begin testing my code.

Thanks

PS. I can send it back tomorrow.

PS2. Please pay the network fee yourself.

Üyeler arasında komisyonsuz BTC ve TL transferini mümkün kılabilirseniz hem kendinize hem kullanıcılara sayısız faydalar sağlamış olursunuz.

Thank you for information, killerstorm, I am a big fan and a follower of your other projects already. I am using Coinprism but don't like the Open Assets Protocol.

Do you know when Mac OS X version of ChromaWallet will be released? And also, I think we need to wait for a stable release to run a business on ChromaWallet, don't we?
120  Bitcoin / Project Development / Re: [IDEA] Project Zero Fees on: June 16, 2014, 02:33:54 AM
Well, yeah, you may be the last resort : )

Is it possible to set the transaction fee to zero in any mining pool such as Cex.io?
