Here is what I said about it in September:
Here is the way I see it!
He puts a large wall up on the sell side, causing people who want to get an order executed to trickle over the top and down in front. He then pulls his order causing a very thin market near the going rate, and he sweeps them up as to not move the price up higher than needed. And, repeat!
On the buy side, it's to show false support (ex. demand), therefore, causing the other buyers to raise their bids, so he can sell higher, and again, not to lower the price more than is necessary!
Then you'll, on occasion, see a rather large wall on both sides! I believe this is when he is taking a break (sleep) so he knows the price will still be where he left it when he picks back up where he left off!
It's mind games really! This is someone with experience in stock trading, manipulation, and psychological reaction, and wanted an easy profit!
I believe he can force the price to where he wants, when he wants! When you have 25K+ BTC, and $100,000 at the same time, well, you have that kind of power!
This was posted not too long ago in another thread:
There are a few things that I have been reticent to talk about, simply because I didn't want the general public to know the stuff that "we" know. However, in the spirit of this thread - helping people to stop losing money - I have decided to share a little.
One of the main and widely-talked about issues is "the manipulator". After watching time and again as individuals have "the hammer" dropped on them, I figured I might as well shed a little light on what may be happening. There are several different strategies being used by a few individuals with "lots" of buying power, so I'll talk a little about the main strategy I see on a daily basis.
The manipulator is basically a large trader who is repetitively practicing a strategy we call "the hammer". It's a simple strategy of deception and can lead to a "crack" in prices. Prior to applying a systematic strategy to the BTC market, I used to trade with him and make a decent profit.
The Hammer (Long)
1. Big trader posts large volume on the ask side
2. Individuals see the ask and try and get in front of him by selling/shorting/lowering their offers
3. He is simultaneously buying at the bid from the small guys
4. As soon as selling volume dries up, he pulls his ask and enters long, causing a jump in prices
5. He sells to the people who buy behind him, scalping a profit
How to Play the Hammer (Long)
1. Watch the volume from the small traders that are trying to trade in front of him
2. When the volume dries up and he pulls his ask - enter long
3. If he doesn't follow soon with a large trade, exit your trade at a scratch or loss
There are several different variants of this strategy, but as a general rule of thumb - if you see a fake bid or ask, the markets are probably going that way soon.
This is more for informative purposes than actual trading advice. See how subjective this is? In my opinion, this type of trading isn't scalable and it doesn't possess long-term profitability, which is what this thread is about. My suggestion is that you take this information as a little "FYI" and stick to a systematic and tested strategy, ignoring the games that go on in the order-book entirely.
