Put call parity. I'd explain but if you are interested google it. The call may not seem to reflect the div. because the call reflects the value of the dividend less the value of the put.

As a Professional option trader I don't use any of these brokers. But if I had the choice of a broker who defaults to P-coast or the ISE. I would choose the ISE. Best executions, Price improvement, fast cancels, tight markets. I don't trust the P-Coast and I trade on the Amex.

I'm trying not to be defensive. A fee gives the exchange more money to buy technology, and discourages the practice that strains the same technology. Apparently the fee is enough of a disincentive to the "abusers." Is this just a convenient way for exchanges to get rid of orders they...

I always hedge deltas. but sometimes I miss the stock. and trades have vega, theta and rho too. so there are alot of ways to lose money on a trade that initially is a winner. MG

It's hard to determine what % of trades are winners. MMs have theoretical edge on most trades. but you can't get a check for theoretical. The hard part of MM is holding a position. I might make money buying options and then lose it back and more in decay until expiration. or sell...

Hostility isn't needed here and I don't accept yours. I've lost money on many trades. congrats on your success. also realize that both sides of an option trade can be winners. So maybe you made money on the trades and I did too. Have a good day trading.

First, I am an option market-maker at an exchange. I don't get paid any money from cancellation fees. Exchanges collect the fees and they aren't making much money. My understanding is the fees were imposed because of the actions of relatively few customers. These customers have used...

when a stock is near an option strike with a large open interest. There is a tendency for it to be pinned near the stock. That is the stock gravitates toward the strike. so now the question is why? If we take as a given that: 1. People are risk averse when it comes to keeping gains...

Everyone seems to be focusing on holdem. It's a great game but may not be the best to learn first. In my experience with online poker, the 7stud games are much more profitable. They have more players who are weak and loose. That is, they don't bet or raise when they are ahead and...
