2421  Bitcoin / Bitcoin Discussion / Re: What have we all learnt from the Mt Gox incident? on: June 20, 2011, 03:37:44 PM

I am not a trader, I develop trading systems software. I've worked on systems that cleaned up the mess when trades get busted, so my attitude is less cavalier than yours. Admittedly, I've dealt only with institutional and larger hedge fund trades that don't typically involve lightly traded securities, so these massive rollbacks could be a more common occurence than I thought.


If you're interested, check out the NANEX folks. They do some interesting plots of issues that have had the same distressing behavior as the indexes when the flash-crash occurred in May. What is alarming is it seems to point the blame at some "alpha testing in the wild" by High Frequency Algorithms, as the patterns produced by sub-pennying bids and offers become apparent.

I've worked on automated trading software, but not like these guys - I actually just want to emulate good trading decisions, not spam an exchange with 1,000 orders a second.

Good luck on your efforts.

Those of us who have worked on real exchanges know that no matter how you do a rollback some innocent party will get screwed in the end.  Usually it is the small guys who get screwed, never the GS, JPMs or the Smith Barneys. Looks like the same thing will happen here. The 500K BTC guy would get most of his coins back but the small timers who traded on good faith during the plunge won't.


If Mt. Gox wants to be taken seriously this should be the first and last time they do this kind of bullshit.


Hey, you. Over there. Yeah, the one who talks big and doesn't know jack.

Guess what the exchanges do every day they have a mini-flash-crash? That's right, there are plenty of smaller stocks that trade say at $12 that get smacked down to 30 cents. The HFT guys are the usual culprit, but all the trades get busted within a certain percentage. Mt. Gox is just following best practices here.

Sorry you don't get it - but you would if you really did 'work on a real exchange'.

Take my trading cards clerk, and get me a hoagie while you run that crap to the back office. Clerk Failpile.

Thanks for the real info, instead of all these paranoia/troll threads.

There's your explanation, people.

At least it's almost back up now Smiley

Protip: When there's a bazillion threads already about the same subject, maybe you are being redundant. Just sayin'.

If you don't mind, I'm going to put up what I saw on bitcoinmonitor.com here, since it is a screen shot thread...

Upon further reflection, seems an order this large could absorb all intervening bids/offers - but you should see those taken out in the trade history, not just crossing at 0.01. So, something is obviously messed up here. Waiting for an official comment from MagicalTux.
2426  Bitcoin / Bitcoin Discussion / Re: does MtGox have incentive to manipulate the market? on: June 19, 2011, 06:19:27 PM
if they THEMSELVES cause panics and selloffs, don't they massively profit on exchanges when the price bounces back up?

what can be done to counter something like this? simply have more exchanges?

As you can already see in some of the threads, an exchange has no incentive to do this, because trust in the exchange would be damaged beyond repair. No trust in an exchange means no trading there - so no fees, and they are done. I'm not sure what happened other than large size - but I'd like to know where that came from.

Perhaps the exchange owners will post, who knows...
2427  Bitcoin / Bitcoin Discussion / Re: Someone cashed out on mtgox - price from $17 to $0.01 in minutes! on: June 19, 2011, 06:14:07 PM
For what it is worth - here's what the size looked on two of the big 'cash out' orders. Sure made no sense to me, since normal markets match best bid/offer instead of crossing at arbitrary prices.

So, anyone know what the heck is going on with Mt.Gox?

Yeah, someone debunked that earlier, but I know in your drama-queen mode about your alleged 'lost' bitcoins you can't let it go. No one cares, sherlock.
2429  Bitcoin / Bitcoin Discussion / Re: I just got hacked - any help is welcome! (25,000 BTC stolen) on: June 18, 2011, 10:30:07 PM

The coins are already traceable... have you heard of the block chain?

Not banned, voluntarily blacklisted by the individual user.

Lets say you sold apples. Would you sell your apples to someone who got their money by stealing it from your neighbor? Maybe you would, but I wouldn't.

This is exactly what we are talking about. Nothing that goes against any of the key strengths of Bitcoin. No changes to the Bitcoin network are required. All that's needed is software that audits the block chain and gives the ability to ignore addresses.

Did you even read it before getting your panties in a bunch?

I'm aware of the blockchain.

You are trying to 'solve' something that turns a system that acts like cash into something that doesn't.

Let us know when the big brother client gets rolling, so I can avoid it Smiley

I don't have specific suggestions, as the wiki and other things are probably enough material.

What I am curious about is what comes out of the conference, as this group would be one of the best 'acid tests' for any obvious problems. Keep us informed, please.

Bitcoin trading, serious business

It is if you aren't trading them in for barbie dreamhouse tokens. I'm sorry if this is an issue for you. They may appreciate one day Smiley

2433  Bitcoin / Bitcoin Discussion / Re: Linkcoin - idea for new type of distributed coinage on: June 18, 2011, 06:54:37 PM

I don't understand why anyone can't modify the data structure you're calling the "next block" to change the transactions to arbitrary ones he chooses. There is no "difficulty" to your process of block creation. One could go back an arbitrary number of blocks, modify a transaction, then recalculate the chained blocks going forward to the present and pass it around as the real block chain.

Any new idea must make it "difficult" to create a block.

You sir, don't understand 'forking' and the difficulty inherent to the process of establishing forged blocks. The resources are out there, even if you refuse to use them.
2434  Bitcoin / Bitcoin Discussion / Re: Do you think lulzsec will target Bitcoin? on: June 18, 2011, 06:51:47 PM

If indeed LulzSec are friends of bitcoin I want them to know that I will make a huge donation to their cause(s) if they would help me recover the funds. I'd be their biggest friend for sure then.



You sir, are a simpering idiot.

Please phone oprah, she may have use for a drama queen on her new network.
2435  Bitcoin / Bitcoin Discussion / Re: Ideas for the Perfect Bitcoin Exchange on: June 18, 2011, 06:50:15 PM
While I encourage the idea of more exchanges (while they are necessary, but that is another topic), I'd reconsider starting one based in the U.S.A. I think all of us can agree that the large banks based in the US will be the first to push back on this idea once it gains enough traction. If you are in the bitcoin business, you better believe that all available pressure/tactics will be used to interfere.

I'd feel better if the principle servers and incorporation occurred outside immediate US jurisdiction. While no-one is perfectly isolated, it would provide some kind of buffer so you could react to legal/governmental demands.
2436  Economy / Speculation / Re: Let the rally begin! on: June 18, 2011, 06:47:00 PM
Nope, but as none of bitcoin speculators already speculated before, bitcoin speculation rules are not traditional speculation rules, therefore even traditional speculators can know how to speculate on bitcoin market
 Grin

Yeah, I see how you went for that whole logical not != thing, but it fails.

Trading applies to anything you can chart. Therefore, any trading experience applies to any tradeable market. While each market has its own 'personality' of sorts, humans are adaptable and able to conform to other environments such as bitcoin trading.

Executive summary:

You're wrong. Completely.

Only a crowd of idiots would gather around a good system and insist it be the exact opposite.

Traceable coins? Banned keys?

What the hell is wrong with you guys? And I do mean that collectively. Talk about design-by-committee. What an utter pile of fail.

Are you high?

Given your insightful and elaborate reply, I've considered every point you presented, down to the helpful and illustrative image supplied. After running through a fourier-transform, checking for stenography and hidden ciphers - I can only come to one conclusion.

You sir, are an unimaginative asshole.

Hope that helps Smiley

Sorry but no, it's going to crash even further in about 3-4 hours time.

This would be a prime example of emotion versus rational logic, since no real explanation is offered beyond the keywords 'crash'. Honestly, have any of you traded anything besides bitcoin before? I truly have to wonder...
