Qt Bitcoin Trader [Open Source secure trading client for Mac/Windows/Linux]

[mojBitcoin.si]

Hi,

I'm trading on Bitstamp and have problems with "All in", Calculator and "Buy All" rule (I didn't have a chance to try Sell all).

Calculator:
Calculations are wrong.
You calculate fee from BTC side in BTC, and from USD side in USD.
Bitstamp always calculates fees from USD.

All In - Buying btc:
When I press "All in" the order is not created, event though populated Total to spend is lower than my Balance.
I think program subtracts a fee from Balance and puts the reminder to Total to spend. Since fee is not calculated correctly, this number can be higher than available balance.

Buy All rule:
Buy All rule doesn't create an order. It looks like the same problem as above.

I'm using QTtrader v.1.07.96 (BETA) in osx.

Otherwise this is great piece of software. Thnx Ighor. If it helps me make better deals then you can be sure to get a donation.

regards,
T.

Possible you downloaded fake/malware app.

Qt Bitcoin Trader for Windows have digital signature.
Please always when you download any exe file for Windows Google it first, find official site, double check source, digital signature and information about this file on http://virustotal.com
Highly recommend to use secure auto update.

Known fake domains and malware trader apps discussed here: https://bitcointalk.org/index.php?topic=400487

Qt Bitcoin Trader does not have withdrawal functionality and API rights allowed only for Trade/Info.
Please report your download link here: https://bitcointalk.org/index.php?topic=400487

It is not fake, I traded at BTC-e but now this happened. The good thing is that I exchanged 1.47 BTC to USD at Bitstamp because 1.47 was already there and I was monitoring blockchain. But look at those adresses with 4, 3, or 37 BTC and at my Bitstamp account was just 1.47. How is that posible to withdraw more than what is at account???

Transaction looks correct. Please contact Bitstamp and find out how withdrawal happend, try to remember recent installed apps, than put information here: https://bitcointalk.org/index.php?topic=400487 to prevent this happend with someone again.

What should I do now? should I delete Qt Bitcoin Trader apps???

PS. I was changing BTC-e HttpRequestInterval to 600 before conecting to Bitstamp if that means something

Do you have saved email server password in browser and you was logged in to bitstamp web site at moment this happend?
If yes, it could be some virus/malware app, if not, your passwords could be stolen.

Check Qt Bitcoin Trader app properties, if there present digital signature (julyighor@gmail.com), it is legit app, so you don't need to remove it.
But if you installed it using some "Installers", not just copying file, this means you used fake installer witch may contains virus.

You should try remember where you downloaded Qt Bitcoin Trader. If it was official source this means you download other malware apps.
Anyway check all system by antivirus and change passwords in all important websites.
And don't use same password to every web site.

I remember that I was checking at Softpedia
-http://www.softpedia.com/get/Others/Finances-Business/Bitcoin-Trader.shtml
but I'm not shore if I downloaded and installed it from there so better not to place it to another post.
I downloaded from sourceforge for shore
-http://sourceforge.net/projects/bitcointrader/

PS. softpedia should be checked...

Softpedia is good. They always check files before publishing. There never was fake versions of my app.
Also I'm checking their links too and I monitoring daily google search results too.

To check is Qt Bitcoin Trader legit app. Just press right button on exe file and click Properties. You should see Digital signature what can not be stolen.

[b0du1]

It's OK I checked the signature and app is placed in my personal folder so it is not from instaler...

I realy don't get it how that happened and wondering if I didn't exchanged BTC->USD  will BTC been stolen?
Looks like malware somehow is trying to withdrow all BTC ballance.
I dont Know what happened. I checked my PC with Emsisoft asquared Antivirus and found nothing except some bad reg keys.

We shall see what will Bitstamp team tell me and if that happened in the same time when Qt BitcoinTrader conected through API. If yes it is interconected somehow with Qt BTC Trader.

I will post it here when they answer me...

[b0du1]

I think that I Know what is all about.

1. Thay done some changes
https://www.bitstamp.net/article/scheduled-downtime/
so now thay have new API with withdrawal option for BTC and RIPLE

2. Those wthdrawal from my adress was probably moving it to cold storage.

So everything is OK...

It seems like the zero profit price value when selling Litecoin for the LTC/BTC symbol in BTC-e exchange is incorrect. It displays values less than 4% than the 'Price per coin' value even though the transaction fee is only 0.20%!!

For example for a 0.02695 sell price it indicates a zero profit price of 0.02584 (That'd be more than 4% fee!!). How so?? Shouldn't it be 0.02689 (0.02695 x 0.998) since the transaction fee is 0.2% ?? 

[b0du1]

...Bitstamp team confirmed that everything is OK

...I was so paranoic, perhaps because I saw that withdrawal (what is thing about how their system works) with conected QtBTrader   showing offline but now with new API key works great
