1  Economy / Service Announcements / Re: [ANN] Bitcoin.de: Marketplace for Europa. Made in Germany. Support-Thread on: May 13, 2014, 11:31:30 AM
If you're looking for charts for bitcoin.de you'll find it here:


Yes you can see market depth. A ruby gem is basically a library to help get data from bitcoin.de written in ruby

I'm rather looking for public API of market depth for bitcoin.de. Not yet available?


I developed a ruby gem in order to get public data from bitcoin.de

https://github.com/jhk753/bitcoinde

Hi,

thank you for your interest. I send it to our technical stuff, please be patient, cause they are very bussy working on bringing our API with that of our partner, the Fidor Bank together and trying to make bitcoin.de a real time exchange.

Cause my background is not IT - what is a ruby gem? Does it show the market depth?

kind regards

Christoph Bergmann

It's an old post but as it the first result that comes from google search, I'll post the ruby gem I developed to access public data from bitcoin.de:

I would seriously consider trading at a volume of about EUR 5-10k per week on your platform, if you would please share the requested information.

5  Bitcoin / Project Development / Ruby gem for hitbtc exchange on: April 29, 2014, 09:23:56 PM
Hello guys,

I quickly put on github a wrapper ruby api for hitbtc.

It still needs testing and implementation of payment api. So for those working on a ruby robot with hitbtc, I'll love some feedbacks (or even contribution)

Thanks

https://github.com/jhk753/hitbtc_ruby
6  Economy / Exchanges / Re: hitBTC.com - super fast and stable BTC/LTC/USD/EUR exchange on: April 29, 2014, 09:20:37 PM
Okay guys, I need testers on the ruby api wrapper!

https://github.com/jhk753/hitbtc_ruby

Let me know what you think
7  Economy / Exchanges / Re: hitBTC.com - super fast and stable BTC/LTC/USD/EUR exchange on: April 29, 2014, 03:34:53 PM
Hey do you also get a bad request at this URL: https://api.hitbtc.com/

What's happening, still working on the API an crashed twice in one day. Trading api was working fine until I get only bad request from my calls

[edit] got back to normal after a 15 min interuption [/edit]

Hey Guys, I'm starting to build a ruby gem wrap up for this as I want to give it a go with a robot
https://github.com/jhk753/hitbtc_ruby

It's not for use already as completely under development, but I ran into a problem. The api limit is not documented and seems to be pretty low...
After a few test calls (maybe 30 in 1 hour) and I'm not able to access their domain from my computer...
It's an hardcore api limit, maybe to prevent DDOS, but you need to do something about it.

thanks

Same question here for R9 290.
Plus I'm in linux and CGminer doesn't show voltage on my card. But if I try to change the voltage, it says that driver accepted but doesn't show any change on cgminer outputs.

I'm not near my rig so I can't check the wall plug, but what do you think it means ? Is CGminer capable of undervolting in Linux with latest beta driver ?
10  Economy / Trading Discussion / Re: ATP [Advanced Trading Platform] on: June 16, 2013, 08:47:44 AM
I'll let the code answer this:

https://github.com/aido/AidoATP/blob/master/src/main/java/org/aido/atp/TrendTradingAgent.java#L267

Code:
if (currentBid.isGreaterThan(vwap)) {
tradeIndicator.put("VWAPCross_Up",true);
} else if (currentAsk.isLessThan(vwap)) {
tradeIndicator.put("VWAPCross_Down",true);
}

So, VWAPCross_Up is true when last price > VWAP (i.e. current price has crossed up above VWAP, up trend) and VWAPCross_Down is true when last price < VWAP (i.e. current price has crossed down below VWAP, down trend).

Maybe Probably my choice of terms 'up' and 'down' was not the best.

The VWAP Cross indicator should probably be used in tandem with one of the other indicators.

Although, looking at the code now my description in the README isn't quite accurate. It uses current bid and current ask instead of last; a slight difference.

This taken into consideration if I want to use vwapcross algo correctly should my ask and bid logic look like this:

ask_logic: ADS_Down && VWAPCross_Down
bid_logic: ADS_Up && VWAPCross_Up

Or did I completely misunderstand the readme:

Quote
The trend observer functionality constantly monitors the market for trends. A combination of the Advance/Decline Spread, SMA and EMA algorithms decide what way the market is trending.

Market Trending Down = Look at buying
Market Trending Up = Look at selling
Once it is decided the trend is up (ask) or down (bid) it then compares the last transaction to the VWAP.

The ratio of last price versus VWAP is used as a waterline to make the final determination that we will take an action.

If trend = down & last < VWAP then buy
If trend = up & last > VWAP then sell

What's your advice on bid and ask logic ?

I advise using bid and ask logic that will make a profit  Grin

Right ! ^^

have you tested some things yet ?
12  Economy / Trading Discussion / Re: ATP [Advanced Trading Platform] on: June 15, 2013, 07:58:58 PM
Hum.

Maybe.

What's your advice on bid and ask logic ?
13  Economy / Trading Discussion / Re: ATP [Advanced Trading Platform] on: June 15, 2013, 07:52:10 PM
Ok thx.
I found an error while testing following trend.

org.codehaus.commons.compiler.CompileException: Line 0, Column 0: Unexpected token "End-Of-File" in primary

It happened when the ticker size was above the minimum I set


Really strange
14  Economy / Trading Discussion / Re: ATP [Advanced Trading Platform] on: June 15, 2013, 06:09:38 PM
Aido,

Could you explain a bit more how your arbitrage algorithm work ?

From what I understand from simulation, you compare changing real currency 1 to real currency 2 through bitcoin and through regular trading ?

So we don't actually make money with this right ? How do we benefit from this.

Example if my local currency is USD, if at t=1 I have an arbitrage with Euro
I trade through bitcoin and get euro. But then if I don't have reverse arbitrage to get back to USD for a while, depending on trends of USD/EURO I may loose money.

Am I wrong ? or did I miss something ?

thanks for your help
15  Economy / Trading Discussion / Re: ATP [Advanced Trading Platform] on: June 15, 2013, 05:28:40 PM
Ok I found it in ~/Library/Preferences/org.aido.atp.plist

16  Economy / Trading Discussion / Re: ATP [Advanced Trading Platform] on: June 15, 2013, 05:21:28 PM
On Windows config is stored in the registry, on Mac its stored in .plist files in ~/Library, and on Linux and friends its stored in ~/.java

Thanks

Edit: Actually I don't see any .plist in ~/Library ... Sad
17  Economy / Trading Discussion / Re: ATP [Advanced Trading Platform] on: June 15, 2013, 04:55:00 PM
Thanks for this.

Just a little question where is the xml config files on MAX OS 10.8

I wanted to try it but I got an error:

"BTCE returned an error: invalid nonce parameter"

So I wanted to use another key/secret, but I don't find the xml and I don't want to go through all the questions each time I change something.

Do you have an idea where it is ?

Thanks a lot

That was server error on their part.

yes , it shows loading error.


But is it because I send too many requests ?
19  Economy / Service Discussion / Re: Resquests limit on BTC-E on: June 10, 2013, 05:00:13 PM

20  Economy / Service Discussion / Resquests limit on BTC-E on: June 10, 2013, 10:57:46 AM
Hi,

I'm trying to code a little bot to trade on BTC-E. But I was wondering if there was a limit on the number of get_depth requests ?

Currently I do 1 or 2 calls per second with the same IP. It works for almost 2 hours and then it crashes Wink

Does someone has anymore information on this ?

Thanks a lot
