Checked it out, did some instant buys, sells, seems to work well so far. See how the withdrawl goes through. I would definitely recommend getting withdrawl to DWOLLA as a choice or paypal if you could pull that off as well, would definitely help the exchange.

Upon looking at the transaction history and my code, the error occurred when you tried to withdraw BTC.
The 'PendingWithdrawl' class wasn't tested properly by myself and a bug got through that allowed an absurd small remainder to remain upon the calculation of the withdrawal fee.
I've sent a bonus .05 BTC for your insightful input and bug catching abilities!.

Wow...looks like you found a rounding error bug. Bitswaps is coded to use 8 decimal places. Your balance reflects a very small amount (10^-15) that should have been rounded to zero during the transaction instead of leaving a tiny remainder.
A balance less than 0.00000001 should have been rounded to 8 decimal places effectively making your balance zero.
Yes, I do understand the complexities of floating point math and I appreciate your help revealing BitSwaps shortcomings.
I will review the transaction history and look into exactly which function caused the error and fix it.
TYSM for your reply! This is what demo testing is for!
I will send .05 BTC to the address in your sig.

Hi folks!
My exchange is getting closer to completion, and I still haven't received any feedback on it from the community, so I'm willing to pay a small fee for your opinion...good or bad!
My exchange is called BitSwaps and it is based on Google's Appengine.
For now, you will need a Gmail account to log in. I will be adding OpenID once appengine fully supports it over https.
I am looking for 10 people who want to try my exchange system and provide some feedback.
Once this round of testing is complete and any necessary changes are made, I will do it again with round 2.
I am specifically looking for people who have trading experience with at least 2 other exchanges.
Testers get a demo account with 100 CAD, 100 USD and 20 BTC.
I would like my testers to make several buy / sell market orders and also try the instant market feature. Testers should also check their transaction history and balances to ensure all trades were completed accurately.
I would also like the testers to try and 'hack' my exchange. Examples would be posting invalid data, negative numbers, absurd inputs etc...and point out any vulnerabilities I may have overlooked.
Beta testers who wish to work with me on a continual basis can also have their names shown on BitSwaps website's team page...I don't mind to give credit where credit is due!
I wish I could pay more for your help, but I am not a miner and only have a small amount of BTC as 'seed' money.
Well, If you have some spare time and would like to help me out, my site is at https://bitswaps.appspot.com
Thank you all in advance.
Steve
