No, what that meant was that human trading is not going to stop their price fixing. And it is not about me, it's about all people long options.

You don't know anything. HFT makes up an enormous percent of the trading that goes on. Human traders are not going to thwart what they decide together to do. Competition between them should prevent this kind of thing, but it doesn't. There is obvious collusion going on. This can be done...

Not all liquidity, just enough to get the price where they want. And with large volume other people or one or two mm asks wouldn't stop it from dropping. The obviousness of it depends how much they do it how quickly. I think you are not understanding the scale of hft trading. Google 5...

Hft market makers if colluding would not need to short fb to drop the price. They would just drop all or most of the ask bids would normally be met by whatever people sold... even if it was equal to the number of shares bought in that minute the price would drop. They can easily pick the price...

An other obvious sign, right before close 100s of thousands of shares bought several times in a row in the span of a few seconds. Each time the price drops back before the next one from HFTs how can they drop the price that quickly and repeatedly while still competing with each other?

fb is an example of what I am talking about. They have a huge increase in advertising, and love to outpace their estimates which means they will likely finaggle their spending etc to beat estimates when they have this much adv growth and ability to do so. Right before earnings the stock drops...

a guy in another thread was talking about how wide the spread on recent options were. I went through the list of all options sold in the last hour or so in large lots. They were all worth one cent less than they sold for even when the underlying price had not moved. This is one thing I am...

That is what I am saying, the share price of the underlying is also moving in relation to option sales.

The events I described were very specific, not just "oh some pinning and low volume moves are common"

Monopolies (vertical or horizontal) are not capitalistic. The governments real one purpose should be to prevent anyone else from becoming a government and stopping competition.

I equate price fixing with them not repopulating the order book. To do these things, they would collude with other HFT market makers and just drop out all the limit orders on one side to let the price go back to where they want it. They could also be doing some trading with each other with an...

The buy pressure is obvious, and in the past has resulted in steady climbs in price (or sell pressure when I had put positions). What is happening now are steady climbs in price followed by ludicrous instantaneous drops on negligible trading volume. This is called hft market makers colluding...

This has absolutely zero to do with anything I was talking about Plausible deniability fail

P.S. > If you go through the list of Option trades for the day sorted by expiration, all the largest positions will be worth less than when purchased or have been sold for less than purchased. They are blatantly price fixing to capture option profits from speculators. Given the recent...

Basically what is happening now is that HFT firms are failing to compete with one another and provide liquidity within certain ranges of price and time so that they can capture as much option profit as possible. There is a special emphasis on options close to expiration that can swing in value...

My bad made some money and "quit" for the day... That is how I make the money My issue is with counter moving as what stardust said. I stare at the option trade history all day. I see single contracts being traded often, and large bundles of contracts being traded that for expirations at...

Because they started perving my account apparently

I've had stupid white trash trying to laugh at my comments because I didn't use gann angles when they didn't even understand derivative analysis the entire time I have been trading... all 10 years and hundreds of thousands of profit So forgive me if I don't care what some snot nosed little...

Why would a textbook on theoretical market making techniques be more accurate than quantitative measurement and profiling of what is actually happening in the market? What it is saying is that someone has to bear the opposing risk on a options contract, which really is common sense. If a...

Well I have traded in the thousands of contracts, but I have toned that down for the time being. I see subpennying activity all the time, and I don't think it is limited to me at all. For instance if there is a bid ask spread and I place a limit between it, it is immediately insulated with...
