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

[takagari]

I realize this is likely been asked, and your priority is to stabalize the current version, but any plans to support Alt coin trading within BTC-e in the future.

Love this app, build an android add-on

Hello!
Just discovered your magnificent software and want to thank you for such magnificent and easy to use tool.

I installed last version QT, created keys on btc connected btc, but after some hours running on his own I found that API was down and API lag indicator showed 9999...

After about half hour and some program resets it connected again, but seems to fall again overnight.

Is that normal behaviour?

My apologies for disturbing, I read most messages, but could not find anything related.

Thanks in advance and my best whishes
(And excuse my English)

API down status appears on this reasons:
1) Exchange is really down and or there DDOS attack.
2) There is to match requests from your IP to exchange.
3) There is DNS or provider problem.

Solutions:
1) No solution, you mast wait until server begin works again.
2) This problem happens if your provider give to clients single IP address and many of them use api with same exchange. Currently capcha is not supported, but I'll add this soon.
For now there is two solutions:

• Make requests interval larger. Go to %localappdata%\QtBitcoinTrader and edit ini file. And set value HttpRequestsInterval to 1000 for example. Or larger if required.
• Only for advanced users. Go to exchange web site and enter capcha. Now you mast get UserAgent and Cookies from your browser and set "Network" section values in ini file: UserAgent=".." and Cookies=".."

Hello again and please accept my excuses for bothering you again.

I changed to 1000 interval request, but overnigth desconnection persists.

During the day I saw some API shutdowns, but those recovered after a while, 30- 45 seconds maximun.
Along the day the API rules ok, but overnight it falls and keeps down forever (9999....), I must close the program, and wait a minimum 10 minutes to recconect.

It seems that rules have no effect, API disconnets either way, with or without rules running
I have a stable and fast connection, 8Mb/4Mb Windows XP, Fixed IP address and GMT +2 zone, if it helps you.
(Sorry but I have no idea about Capcha, and didn't find it on btc)

Can you suggest a way to find the cause.
Thanks in advance and again excuse for so much trouble.

It seems the zero profit calculation is wrong. E.g.

BTC 1
Rate 0.00624
Total to buy 160.256
Zero Profit price 0.00726 <<<<<< that should be about 0.00630

.... Unless I'm missing something it does not support Alt Coin trading from BTC-E? Or am I missing an option? Mine only show's usd/BTC, would be nice to see it list what I could have for alt's as well etc.

Click on where it says Symbol top left. You get all the trading pairs.

Hi. Please contact me via email or skype (julyighor).

What price? Zero profit price depends only from Price.

In order to change currency you need to remove all rules.

I have no rules, this is in the buy or sell side. It never used to be wrong, it is now. And pressing the "generate subsequent order" APPLY button creates the SELL side at 16% when you have %0 Try it.

Thanks, I'll fix this.

Hello again,

Concerning API shutdowns, it seems that changing request intervals to 600ms did the trick, and keep API alive and working all night long.

Maybe if it's not too complicated, you can add an adaptive "extra delay" when api errors persist more than a few seconds.
It seems to me that client keep trying to connect and BTC persists rejecting longer each time, so when shutdown time is large (9999...) you must wait some 5 - 10 minutes before being allowed to connect again.

I can perfectly live with the program as it works now, but maybe it could be helpful on high traffic scenarios.

Again thanks for your excelent help and support.
Best whishes

Ah it all make's sense now! So you can't set a rule and switch floor's. gotcha!

Thanks for confirmation of minimum interval. I'll force all users to minimum 600 ms interval.
Also I'll add API Down solution. So it will emulate browser and cookies will be saved to solve IP ban problem.

Welp, finally got a working client compiled... was getting myself all worked up, I was missing something stupidly obvious, which I fixed right away after stepping away from it a couple days, and busily tinkering now.

Quick question...

When I have "Delay between executing orders" checked, how long is the delay? (using an unmodified build right now)
and, which configuration option controls that? (and is it in seconds or milliseconds?)

[takagari]

Any chance ANY you can add in support for www.cavirtex.com

I'd love a Canadian trader client!

Currently it 5000 ms.
You can change it in ini file section UI, value RulesSafeModeInterval=5000

Soon I'll add rule to make custom intervals.

I have a lot of suggestions, but I'll add most popular exchanges first.
Also I think to make some easy tool to generate information for adding exchanges to allow everyone submit this data to me. Than I'll add exchanges match faster.
So keep tracking updates.

Custom intervals? Like, setting each rule to its own interval? (could be very handy if you want one rule to fire slower than another one... so a rule set up to catch a big swing can fire off faster than the every-day slow one, to take most advantage of the swing before it swings back)

No. You will be able to add "Empty" rule witch just holds next rule executing by some ms.
So you can put this empty rule between required two rules and make interval.

um... ya sure that is working as intended?

When I had the delay turned off, my trades were going through at roughly 5-6 seconds apart, but when I turn it on, it sits there waiting... couldn't find out exactly how long it would wait, as my buy condition stopped being valid after about 20 minutes.

(I'm also working with source at least a week old, so if you made changes since then, lemme know)

Seems to be great software, just testing now, it works very smoothly in win 8.1 on vm.

I wonder if possible to add- if market last price goes to more or less than X % of market high price or low price then execute rule?

also seems bid and ask label is reversed in last trade tab

[Danman]

Hi guys,
I read several pages of this thread which is mostly about bugfixing, checked out the website and youtube but didn't find any:

I whish there was a manual which explains all the buttons, what exactely last, market, rule, high prices etc. are and what best practices should be used, i.e. what set of rules for specific trading strategies. Sorry I am a newbie and lost money in the hundreds for not understanding the software.

Has anyone written something similar?

Thanks,
Danman
