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

[mikenash100]

This project does sound very promising and i can forsee where it can be valuable...

Next, please pardon me and the fact that i haven't read all the posts in this thread, so i don't know if this has been discussed, but one possible problem i see is from the exchanges - mtgox, etc. Isn't it remotely possible that they could notice some 'unusual activity' going on in their system from the client side of things. e.g. noticing an 'unusually' high number of buy/sell trades coming from one account/IP address/etc, and/or perhaps an unusually tight or small buy/sell price margins. eg, buy = $100; sell = $101... more so if there are lots of these in a short space of time. Could these be red flag to exchanges?

More so given the newness of these exchanges and the issues people report about some of them. eg coinbase and their "high risk" transactions that people here say coibase talks about?

Ok, well... I dunno about the 'newness' of the exchanges... MtGox has been around for, what... around 4 years now? It handles a massive amount of trade volume, and they have been dealing with bots (and other utilities that use their API) for a long time now.

BTCe as well. Right now they have 996 accounts logged in via their API (of course, not all of them are bots, but I would say a majority, if not most, of them are)

Trades through their APIs take less overhead than trades placed through the web front end.

The way the prices between both of these tend to stay reasonably close to each other (although, not as close as they used to, but that has more to do with the difficulties of moving funds between them than the bots), easily most of that is from bots doing arbitrage between the exchanges when the prices diverge enough to make it profitable.

This client, can't do any more than the exchanges allow us to via the APIs they have created.

There will be more ability to configure the trading client's behavior soon, which should help diversify the automated trading strategies we use, and while some of us, I'm sure, will be firing off a lot of small rapid trades as possible (inevitably), many of us won't be doing that.

If the exchange's APIs become a problem for them, they can tweak them as necessary, and the client will follow suit, if need be.

(some of the smaller exchanges may end up having problems with the volume on their APIs, but that is a problem with their implementation, not the client. Unless they're stupid, they will treat it as an opportunity to further optimize their APIs, which would be to their benefit in the long run.

I am using the latest BETA version and it is great, the only thing I really miss is that the "refresh" of the order book is sometimes not fast enough.
When there are big price swings on Bitstamp every second matters and when I am entering a new buy or sell through the QT trader it takes a good 6 or 7 seconds before it is placed. The prices I see in the Order book are also delayed with at least 5 to 7 seconds.

So I usually end up opening Bitcoinwisdom.com and following the buy/sell orders from there as it is real-time.

If IGHOR could create a "pro" version of this tool with real-time trading I am sure a lot of people would be willing to pay for it.
The current version can be left as the "lite" or "free" version.

Hi. Bitstamp API is very slow because of 600 requests per 10 min limitation.
And there about 7 different requests send one by one. But if you open order this request is sent first of all query, so order placed fast, but displayed on UI with delay.
I'm working on new version called Qt Open Trader and I'll bring real time updates for all exchanges.

Just released bugfix update.

Fixed critical bug when program crashes.
Fixed open orders table sorting.

Added delay (5 sec) between rule executed  enabled by default.
Be careful to create rules, think about all variants.
If you create rule group Buy->Sell->Enable all rules, and if market buy/sell prices will become equal your buy/sell prices (both) there can me generated very many transactions, so if you don't understand completely what you do, please leave delay between rule executed On.

Thanks all for testing, bug reports and donations!

I would love for this to support LTC trading on supporting exchanges.

Please add LTC/USD for BTC-E.

Thanks :p

I created a rule:
If market last price <890, spend all my funds (on BTC E)

However, it doesn't place any orders when triggered? It says 'done', but my USD still sits there. Nothing happens.
If I place a buy rule with a set BTC amount, it works fine. Is this bugged?

Am I missing something here? I placed a sell order earlier and it worked fine.

Hey there;

I updated yesterday and now I found this bug:



The BTC and the P are inverted in the Amount and Total fields. This is a Sell order of PPC 36.68..  for BTC0.21

Awesome. Thanks.

Rules performance test.

Created 150 groups, added 5 rules in each group with triggering by different indicators in "Simulateus" mode.

Test results :

Program starting: 30-60 seconds.
CPU time per one indicator change: 1-2 ms.

And there is no limitation for groups or rules count.

Try remove project and download it from Github again.
Maybe some old files left.

I have downloaded it new from here:
https://codeload.github.com/JulyIGHOR/QtBitcoinTrader/tar.gz/v1.07.96.3

Really wired, because your error tells feecalculator.ui file is to old.
Remove all project files and try this one https://downloads.sourceforge.net/project/bitcointrader/SRC/QtBitcoinTrader_Lastest.zip

Thanks, once you pointed that out I realized you could select your currency on the top left Though it's not showing me as having any balance, why is that?
