Wall Observer - MtGoxUSD wall movement tracker

[ManBearPig]

This is what I'm saying: I'm looking at ALL trades on multiple charts, I don't see a ton of 0.01 or 0.02 trades, just normal, low-volume trade going on.

The attackers choose a high and a low point:

Put in spread bids at desired low-price, begin sell-off and commence DDoS at the same time.

This is the only thing that makes sense unless you have a tin-foil hat.

Would be interesting to look at the pattern of Bid wall development right before this happens.

I should screen record the next one.

mtgox.com is still up and responding well tho?

Yes indeed the front-end and trade servers MUST BE different for sure.

Lag appeared to be dropping rapidly a couple minutes ago. Fell form 30+ and settled around 28 and is hovering.

Is it possible the lag is caused by too many people updating/entering orders simultaneously?

0.04's at the moment.

Looks like you don't get my point. How external attackers can access servers inside gox infrastructure? This is pretty unbelievable.

It would need to be a hell of a spike in order changing.

I don't know what percentage of orders are short-lived, in that they are either market orders or Bid or Asks who almost immediately get filled.

I suspect most orders are short-lived - just a hunch.

I know an answer. Gox just wish to register new Guinness book record -- slowest market crash in a history.

Step 1: Wait for spread.
Step 2: Make 3 accounts.
Step 3: Deposit 0.5 bitcoin into each.
Step 4: Sell 0.5 bitcoin from one of them.
Step 5: Make a bot that buys your own 0.5 bitcoin back over and over and over for 0% fee until spread closes.

Down to 25.50... and we get another big seller.

I see the 0.04s surely they alone are not enough to cause this. Maybe they ARE a means of synchronising the attack somehow?

With free trades you could do this all day, only paying for the DDoS botnet time.

Yep, that works.

I would imagine more accounts than 3 though.

Mt.Gox is killing Bitcoin.

Lag --> Fear --> Selling --> More lag --> Panic --> Dumping --> Even more lag.

I have not touched Mt.Gox in a couple of years, but the prices on all other exchanges are suffering because of their failure.

Exodus!

Maybe there is another way... Changing a property about the order or something which doesn't cost the manipulator but is costly computationally and repeating it dozens or hundreds of times a second. Without being on the gox servers, no real way to tell.

1500 btc wall on 100 half an hour ago. I guess that's broken long time ago.

Ah, yes, I believe that's the cause right there. When a large market sell order is executed, the matching engine needs to confirm that the USD is in the account for every single bid getting filled.

As someone mentioned earlier, new hardware won't fix this (Gox is supposedly using SSD now). It's the code but at least Gox is planning on fixing this soon.

1. Deposit 1USD to a dummy account
2. Create 10000 bid orders of 0.01BTC at $0.01 slowly (without creating lag)
3. Sell off
4. Rapidly adding new orders to the dummy account
5. The MtG card trading engine is forced to re-evaluate the validity of the 10000 bid orders
6. 30 minutes lag
7. Profit

Does it work?

can't help myself but I keep on hitting the F5 button on Gox

[Krabby]

Are we going down? Gulp.
