Case study:

Guys, it's only a 1000btc wall... It's not trying to manipulate or anything, he just wants to sell, poor him...

You may be right, as his wall is being nibbled on quite a bit.   I find it surprising that selling pressure is so low that hardly any asks are being placed beneath it.  
He has to know if he backed the wall to 105, he would end up with $5k more . . .   Strange not to at this point unless he is trying to manipulate, very odd.

He's setting up a triangle. 104 is the center-line.

Used 0.01 add/rem bidspamming to quench volume of the uptrend. (Lag hovered at 1-2 minutes during insignificant price action.)

(Visible on Clark Moody if you check "Show Depth Messages in Console.")

Placed the top wall to force creation of the triangle, placed the mid wall to contain it, and lastly the lower wall to finish it.

You can see it for yourself in DougTanner's wallpic:





THAT 1000BTC wall was just eaten.
Impossibruuuu!
Didn't you understand? This wall was manipulation! You can't just go and eat him!  Cheesy

Of course you can eat a manipulation wall, if you do it in one big bite.  Tongue  This wall was acting different however, and I am pretty sure he just wanted to sell, though he could have made several more thousand if he wanted, not smart.



Someone bought out the lower wall. Brand new 15K BTC ask wall appears at 130.

Effect on bid/ask spread:

-4.5 bucks across 11M BTC is 49,5 million reduction in "market cap", for which the seller received only ~300K USD.

Gaming app ENSLAVES punter PCs in Bitcoin mining ring
Some secret software to go with your deathmatch, sir?

Jack Clark, San Francisco, 2nd May 2013 00:23 GMT

A competitive gaming company has admitted that for two weeks in April its software client was hijacking league members' PCs to mine Bitcoins.

In an eyebrow-raising turn of events, the company, ESEA Gaming, admitted on Wednesday that its software client had been running Bitcoin-mining algorithms on customer PCs since April 14, generating over $3,700 worth of the virtual currency – not to mention a likely uptick in the electricity bills of the unwitting punters whose graphics cards' GPUs been forced to mine the virtual currency.

Angel Investor, Spotify Fixer Shakil Khan Launches Coindesk, A Bitcoin Resource

KIM-MAI CUTLER

Shakil Khan, an angel investor and advisor to Spotify, just launched Coindesk, a Bitcoin resource and news site, amid a boatload of hype and VC interest in the crypto-currency.

Khan says Coindesk was a project he conceived of about four weeks ago, around when Bitcoin was surging to an all-time high. It’s now trading at around $124.38, or about half as much as it was trading at a few weeks ago.

“I was just sitting there and I literally had five e-mails that day from very seasoned entrepreneurs, asking me — what do you know about Bitcoin?” said Khan, who has invested in the space. He was part of a roughly half-million dollar round in Bitpay, which is trying to make it dead simple for merchants to incorporate Bitcoin as a payments method.

Ashton Kutcher Bites Into 'Bitcoin Revolution'
Published: Wednesday, 1 May 2013 | 3:37 PM ET
By: Cadie Thompson
Technology Editor, CNBC.com

The "bitcoin revolution" is here, and it offers an investing opportunity, Ashton Kutcher tells the TechCrunch Disrupt conference Wednesday.

"I think bitcoins are obviously becoming more and more relevant," said the actor, who is also founder of the A-Grade venture firm.

"The fact that people are hacking bitcoins really hard, it almost hearkens back to when banks first started and they didn't have safe safes and people were going into the banks and just robbing money out of the safe. It actually validates the value of the money itself," he said. "I think the fact that you can buy drugs and ammo with it is actually (a) validator of the currency itself."

you missed it buddy...

the market intentionally minimizes your profits.

in other words, not only does it not care what you want, if it knows what you want, you won't get it Tongue
556  Economy / Speculation / Re: does price manipulation break standard methods of TA? on: May 01, 2013, 04:10:19 PM
We have some important questions remaining:

• Is it possible to correctly anticipate the direction of the market reaction to brief "unanticipated" market events and/or external news?
• Is the same possible for someone who has full advance knowledge of the otherwise unanticipated  event/external news?
• Is it possible to reliably predict the magnitude or extent of the reaction to some particular event or piece of new information?

I very strongly suspect the answer is yes the first two questions, especially the second, and likely no to the third.

For some particular events you can "reliably" anticipate the direction of the resulting action.
(More often than not, and also often enough to be profitable by a good margin.)

Tricky points to prove. I suspect behavioral economics already has the answers. I'll see what I can find.



Next... Fear and Surprise or how to Exploit Neuroeconomics for Market Manipulation...

Whether you want to directly manipulate the price, or you use some external events, such as,
for example "DDOSing Mt.Gox" attacks or the "Associated Press, Twitter hack",
You want to pull of your manipulation event so that the market has a very little time to react,
you want to force each player to make a decision to either "abandon ship" or "get on board",
before they have time to calmly and reasonably analyze the situation.

In either case you attempt to trigger the fear response:
If "news" news: the fear of holding the bag.
If "good" news: the fear of getting left behind.

[To be cont'd...]

2: Will tend to play out in a predictable direction. (To the manipulator, yet unpredictable from TA),

sticking point:

i opened this thread with the hypothesis that "TA-appropriate moves" maximize the profit/risk equation. you've brought up many good points why this may not be the case.

however, the quoted point above speaks to a very important feature of this problem, that is the feature of the information that the players have.

we all can agree, i hope, that the manipulator does not know, with any certainty, how the market will react to his attempt at manipulation.
the best he can do, just like every other participant, is to guess. doesn't this alone invalidate all theories of direct price manipulation?

Doesn't this alone invalidate all theories against direct price manipulation:

Quote from: Time Magazine
At 1:07 p.m. on Tuesday, the Twitter feed of the Associated Press told us that Barack Obama had been injured in an explosion at the White House.

The tweet was fake — the product of a hack — but given the events in Boston last week, the news spread like wildfire, garnering more that 4,000 retweets.

The AP quickly addressed the situation, suspending its Twitter account, and alerting readers through associated accounts that the tweet describing an explosion at the White House was the result of a hack.  

No harm, no foul, right?

Well, not exactly. According to the Financial Times, that one tweet sent shock waves through the stock market —
causing the S&P 500 to decline 0.9% — enough to wipe out $130 billion in stock value in a matter of seconds.


Source: http://business.time.com/2013/04/24/how-does-one-fake-tweet-cause-a-stock-market-crash/

I would bet that the people behind this trick correctly anticipated the direction of the reaction. And also that there would be a reversal.

I would bet against them knowing with certainty the extent of the reaction or the precise timing of the reversal.

I would bet that what small edge they did have (such as advance knowledge, timing) was sufficient.

You can say "but you don't know that" and you'd be right. And you'd be a right fool too.  Wink
558  Economy / Speculation / Re: does price manipulation break standard methods of TA? on: May 01, 2013, 12:19:22 PM
i see that. there's been a whole lot of questionable price action on gox these days....

i'm starting to regret so many people knowing about bitcoin -- it always attracts the worst first  Tongue

lag >7 min now, most definitely directly because of this.

You can try to predict the actions of the masses with some success but not the action of 1 or 2 people and that's all it takes to move things considerably in this market.

again, the basis of my argument against the perceived 'absolute power' or manipulators, or even just traders with large amounts of capital proportional to the market cap, is that the self-regulating nature of the market makes direct price manipulation proportionally expensive to its magnitude.

this being said, it shouldn't necessarily "break" the various methods of TA. for instance, it's interesting that the large move was timed perfectly with the triangle consolidation. these moves are more predictable than you think.



Does it not seem like certain tactics, unpredictable from a TA framework, which we may call price manipulation:

1: Can allow a trader to incite movement with disproportional effect relative to the cause.
2: Will tend to play out in a predictable direction. (To the manipulator, yet unpredictable from TA),
3: Can be executed / set in motion at a specific and particularly suitable time. (Known to the manipulator, unknowable* to the market at large).
4: Results in changing market conditions which impact the data relevant to technical analysis, often invalidating previous analysis.
5: Plays out in a such a manner that post-fact analysis will "agree" with the manipulator, especially after the rest of the market has started chasing the manipulator**, causing players*** to agree with and, react to the movement of the manipulator, joining the manipulator in the same direction as the initial movement.****

6: That this can cause the cost of initiating the tactic (which might otherwise be prohibitive) to be greatly discounted by knock-on effects of some market participants "piling on" to an initial movement, joining the manipulator which predictably (how predictable?) leads to a cascade/amplification effect.
7: That such a cascade/amplification effect brings the cost of manipulation down, and adds to the reward of manipulation.
8: That such a cascade/amplification effect tends to benefit "the leader", but comes at a cost to "the followers."
9: That initial followers of the "manipulator" stands to benefit, "ahead of the pack" followers benefit some, "average" followers benefit none, and "later than average" followers being hurt.
10: That knowledge of such an effect can prime the market, creating further incentive to be among the initial followers, amplyfying cascade effect, if similar events were to reoccur.

11: That all of the above is consistent with a notion of "rational" manipulation tactics (and a small number of rational initial "followers".)
12: And also, a greater number of irrational "lemmings", giving chase to their disadvantage.
13: That since TA is a delayed reaction (immediate changes taking time to propagate into the data) The technical analysts,  as well as those that follow them, are at greater risk of ending up among the "lemmings" if and when such events do in fact occur.




Note: This picture assumes a single manipulator entity, which is unlikely in practice, or if it were so, is unlikely to be stable, since other agents will pick up on and try to emulate any successful tactic, which creates competition between would-be-manipulators, which complitates the course of events for everyone, and should perhaps be anticipated to lead to a reversion to normality as the market matures. However, there would be windows and moments of time where manipulation tactics remain profitable.

This currently seems to be the case. If and when manipulation tactics seize to be profitable (to the manipulators and the early followers),
or those who would be lemmings recognize that they missed their window, and are being lead to jump up a cliff,
we predict that such manipulation tactics should be diminished in effect and frequency, or stop all-together.



* Unknowable in the details. General features can be anticipated,  <<justification-of-this-point-goes-here>> A discussion of this point could be worthwhile.
** Which they should, as can be argued. (So long as they are quick enough to be among the first to respond.)
*** Humans, bots, algorithms, technical analysis -- as well as the heuristics on which all of those rely to make BUY/SELL/NO ACTION decisions.)
**** Initially, at the start of the motion, first wave of re-action is almost always in the same direction as the initiating action,
however, if the attempt is partially or wholly unsuccessful, things get... complicated.

yes, i was watching, and it was clear that the dump was a single or a few entities, not an emergent movement. there's a lot of bearish news in the air, and the market is short-term overbought. i'm trying to determine if we should expect $120 to hold, or if we're gearing up for a correction-to-the-correction of the bullish move to $165. i highly suspect these individuals were attempting to 'paint the tape', as a very bullish consolidation turned very suddenly into a very bearish picture. this event will be good to consider in another problem i'm working on, can/does price manipulation break standard methods of TA?.


Thoughts?

500 buy on 140, then 500 sell back to 136 in 5 seconds.

Profit: -36.60 BTC. Ouch. Make sure your buy and sell orders don't overlap, guys... Wink

(This will happen if your orderbook has a limit ask for some low price, and you later enter a bid order for some higher price.)
