Topic: Bitcoin-24.com matching engine seems broken, site down. - page 19. (Read 64428 times)

if anyone is to lose out it should be bitcoin24 as they will (morally at least(!)) have to settle their customers' accounts whilst also taking the hit of whatever bitcoins were wrongly credited by the trading engine and quickly extracted. the admin hasn't disappeared just yet (posted on reddit earlier) so i haven't lost all hope.

nowhere - it doesn't really exist other than in bitcoin24's database. for whatever reason, the trading engine is spazzing out and crediting twice (or more) for trades in some instances. it doesn't matter how i'm buying from or selling to really, because the amount of free coins being made out of thin air by the bug makes it impossible to lose.

i tested this last night when i was the only one on it (seemingly). i don't mind detailing this now because the site is properly down and no-one can get in to take advantage, but if i'd revealed how as soon as i knew this could have been happening for hours. from memory i did:

make buy order 1 btc @ ~80 euro
make buy order 1 btc @ ~80 euro
account is credited for 3 btc, only 160 euro taken

make sell order 0.1 btc @ ~77 euro
x30

account is credited for 4.5btc worth of trades @ 77euro/btc

so i ended up with approximately +200EUR more than when i started over the course of a few minutes and just some quick clicking. really i should have been down about 6EUR i guess.

i was clicking very rapidly when making the buy/sell orders in order to reproduce the glitches i'd read about and it obviously worked very well. however even when NOT trying to induce a problem the glitch would still occur - i made a small trade just so i could see if the BTC withdrawal function was working, and ended up getting credited two or three times. just a simple, one click buy order, with no load on the engine as i was just about the only person there. something is clearly very wrong. i wasn't on the exchange this time yesterday but i can see why it was taken offline so abruptly if this was happening. it also explains why the hotwallet is being kept empty - if everyone draws out their coins this can't be corrected. if the coins stay in the system, the database of trades can be rolled back (as i understand it) and BTC/EUR/USD balances can be restored to something resembling 'normality' before the glitch.

From all the users funds???

Damn...

But from where comes the opposite for your trade? do you need to do "crosstrade", trade with yourself? You dont trade/match with other orders from other market participants, right?
From where comes the money (200 eur) you earned?

I like to understand the leak.

Thanks

on an exchange that is effectively live though? while his customers still have active orders, no less.

i think someone has just worked out how to access the exchange and is taking advantage of the glitch to inflate their balance. you can see that orders are regularly executed twice, giving double coins/EUR, which you can then trade the opposite way in multiple tiny orders and have many of those executed twice too. end result = free money essentially. i tried it briefly few hours ago and increased my EUR balance by 200 in about 5 mins... stopped straight away of course (and am ready/willing to hand the funds back)

trading engine is an absolute joke atm - this is why i didn't want to share how to get in

Maybe he is testing the new code.

notice how all the latest ones have executed in duplicate/triplicate too. always the sign of a healthy trading engine

was it possible from bitcoin-24 send own bitcoins to another wallet? Do you think would be possible is somehow now?

Exactly. And if that happens people would probably never get their money.

  i imagine the police to confiscate the hardware... this would mean the police stores the stuff in some basement forever because they dont know how to handle anything related to IT.

Cross posting for a noob who doesn't have access

Well shit. I have money in deposit there.
 
And who are trading in Eur now?
o-O

Did he do something stupid like leave API access active when he "shutdown" the site?  If so and there is a flaw in the trading engine well that would be ... bad right?

In USD no trades, ...
