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

[wc4482]

I'm still running into issues where my all-in buy limit order does not go through, about half the time.

I wonder if this is due to the way Bitstamp calculates it's trading fee. I notice that when the buy-in does not go through, if I move the 0.0X digit one lower and it always goes through.

See below from: https://www.bitstamp.net/fee_schedule/

FEE ROUNDING We kindly ask our users to take note on Bitstamp's policy regarding fee calculation. As our fees are calculated to two decimal places, all fees which might exceed this limitation are rounded up. The rounding up is executed in such a way, that the second decimal digit is always one digit value higher than it was before the rounding up. For example; a fee of 0.111 will be charged as 0.12.

It could also have something to do with doing the calculations with floating point numbers instead of integers (# of satoshis) and bad rounding when converting the results back to satoshi-integers getting passed back to the API, and ending up trying to buy (or sell) more than your available balance will allow. Like with 5/4 rounding.

Hello,

i have tried to compile the Trader on my Cubietruck (arm). I get the following error at the end when i am running

Code:

make

This is the error i get:

Code:

/usr/bin/ld: cannot find -lQtOpenGL
collect2: Fehler: ld gab 1 als Ende-Status zurück
make: *** [QtBitcoinTrader] Fehler 1

Any idea how to fix it?

You need to install or compile Qt SDK first.

[takagari]

Any chance you've looked at cavirtex.com to sed if it can be supported? Would love to be able to do this with Canadian exchange!

Thank you again. Love it!

Hi IGHOR!

Have you noticed that if you go All In to make a bid or to make an ask, it puts the total amount of your USD minus your trading fee, and then when it calculates how many btc you will receive it discounts your trading fee again, so in one buy or sell the QtBT "eats" double fee. Is it happening to anyone else?

Greetings!

You see real values you will receive after buy/sell considering fee.

Ighor, could you please respond to my earlier question?

Anyone else on Bitstamp having problems with submitting all-in bids?

I mean, for example, if i go "all in" and my USD amount is 1000 USD, when i click all in, only 998 USD will appear in my "total to expend" box. I am also using bitstamp.

Please pick maximum value possible to open order to cover all your balance. And send me this exact balance with exact maximum value of BTC.
Chose price lower than current market price to prevent order execution.

really nice built it on linux fine.
Can i suggest you incorporate TradingView.com as charts, hands down the best charts you can find, just whack it in a webview or something...
I am loving the "rules" i would love to see email and sms as a "action" for the rules.

Hey IGHOR,

I think something has changed since the last version, I found a bug on the NMC/BTC pair for BTC-e.

Both Zero profit Price and Zero profit Step are showing wrong calculations. I didn't do the exact numbers but think they're off by an order of magnitude.

Fixed. Update will be available soon.

IGHOR...

I also found an issue with the .map files for the exchanges (and trading pairs) for BTCe.

I had to change LTC/BTC and TRC/BTC, for instance, as they listed the minimum quantity to trade as 0.01, while their minimums are 0.1

BTC/USD is fine with 0.01

I used to have a list of all of those limitations for BTCe... somewhere on my drive. I'll try and hunt it down, and send you an updated .map file for BTCe's pairs.

I noticed this while I was trying to figure out why trades weren't executing, and I noticed that the minimum-amount trades were too low to execute.

I'll also test the minimum price allowed for each pair and get that current too.

OK so there are two qmake commands there -

qmake-qt4 QtBitcoinTrader_Mobility.pro

qmake-qt4 QtBitcoinTrader_Desktop.pro

both for linux.

I'm running mint on a desktop so should I go for the Debian/Ubuntu etc line, or for the all linux Mobility.pro line ?

Try QtBitcoinTrader_Desktop.pro
If not works, than try QtBitcoinTrader_Mobility.pro

Can i change my password on qt trader?

Can i change my password on qt trader?

Currently it not supported.
So you need to remove profile and create new one.

[Squeaker]

You can create a new profile with the new password, and then copy the settings data (like the UI settings and the rules section) over from the old .ini file to the new one.
