How long until consumers catch on and stop throwing money away?

The new note has a .2 inch bigger screen... and the price drops 4 bucks? Please.

When will the SEC step up their game and stop the order spoofing being used to fix prices and devalue options. A tiny amount of mathematical abstraction and apparently the rules don't apply anymore. HFT market makers are making millions a day on this.

The thing that you seem to have difficulty understanding is that we are not talking about you trading from your mom's basement using techniques you read about in a textbook given to you by brokers who bank on your hedging using such methods. We are talking about people who can hedge by flashing...

What is not a difficult concept is the fact that someone has to take the other side of the position for you to hedge. Who? There are more calls outstanding than puts by a factor of 2 on this stock. They may hedge somewhat to stop a catastrophic loss, but they are exposed. Maybe it has...

Seriously? If there are 10000 calls out and 5000 puts then someone is losing if the stock goes down. Forex, the price of the option is less important than the issue of when they were sold. Investor sentiment drove up AAPL's price, Market Makers caused it to fall back down. They would rather...

Everyone expects it to go up to 100. There was strong investor sentiment and pressure to push it up all morning. Only, since everyone expects it there were more than 2x the number of calls sold as puts. Therefore, the HFT market makers with the large share of the market just wait until the...

I don't need to exercise them, I just sell them when they are at a higher price than I paid. They don't need to be in the money to do this either, although their value drops rapidly as in once every time the stock moves against them in an hour or so.

What I am talking about is basically this. There is someone with most of the clout (or several someones working together using game theory algorithms) who makes the market. Say there are an equal number of shares traded in each direction. All they have to do is delete half of the the high...

Every time I come on here some moron tries to tell me I'm the one who is clueless as they demonstrate a complete lack of math and logic skills. Lawsuits against TD are easy to look up. Trading close to expiration is a whole different ball game, and greeks are useless for the most part. Just...

I've read about some lawsuits and horror stories with this broker. I've figured out a few ways in which the derivative market is rigged to try to stop exceptionally high returns, but I am partially wondering if TDAmeritrade (which apparently has a market making branch) is also using access to...

http://blogs.law.harvard.edu/corpgov/2014/05/23/increased-scrutiny-of-high-frequency-trading/ I've already explained several of the techniques, here it goes into more detail and discusses ongoing litigation against them.

Whenever a large lot of option contracts is purchased they simply set the price to devalue that lot of options as long as it doesn't bring another lot into the money. They are colluding to fix the prices by disappearing large amounts of market liquidity in between order book reports and...

They do not hedge by buying the underlying right away. The stock price always drops drastically right after a large call purchase. They simply remove liquidity to control the stock price. What you said is ridiculous. They would need more than 100 times the capital to hedge by purchasing...

You are so clueless. That never, ever happened during the course of the day as reported by Level 2, which reports human activity. HFT activity on the other hand always buys and sells in 1 order lots that are being placed in nanoseconds (for stocks with higher prices). If everyone has calls on...

The collusion part is a different issue. The macro situation with facebook is pretty suspect all on it's own, with the price dropping to before earnings level... earnings where they doubled estimates. Not surprisingly, the price it almost shot to was between two enormous option open interests...

I'm watching it go up 10 cents on one million volume, then drop 10 cents on 80k volume. So obvious.

This isn't hedging pressure, it has popped up a dollar and flashed back every minute along the way and then drops to below the level it was before earnings. AAPL is forced down to. Obviously this activity is to collect derivative money, where most of the money is at these days. The new prices...

Are you a billion dollar hft firm? No... so I'm not talking to you.

I've seen at least widespread subpennying on the options. When I put in an order in the middle of the spread it is instantly insulated by many orders. Wait a second, do it again... same thing. The only way I get in is by accepting temporary loss and I get out when it goes even higher after...
