Thanks for explaining that kostia00.

Yes I have noticed this as well. I hadn't placed any OPG orders since maybe Early November and last I remember this strange behavior hadn't started at that point so this must have started sometime in the past 2 months. I've been placing a number of opening orders since late December and have...

If the entry and exit is in the same day don't use the adjusted close. Since your holding time is entirely intraday, you don't need to adjust for splits or dividends. Also, don't assume you'll be able to get the closing price for the day on an illiquid stock. In real trading it is fairly easy...

A few years back I backtested some simple ideas using some very low quality EOD option price data. I don't exactly remember the results, but the main thing I remember was that most of the time I could take an entry/exit strategy that backtested profitably in the underlying, but would backtest...

Thanks, how does option charm help one to make money selling OOM puts? (I didn't find any explanation for how this might work from googling it.)

Tthoreau777, can you please explain what you mean by the "option charm"?

My impression of the article is that the "Asian Mother" method may be a great way of raising a kid who ends up getting into Medical School someday, but it's not exactly going to raise many captains of industry. Kids who grow up like that learn to please the authority figures (parents, teachers...

I think I remember reading a little while back that this has already happened. If I recall correctly the gist, was that the Wilkevoss brothers had later formed some other internet company that never went anywhere with another investor. The other investor claims that they had an agreement that...

I remember reading that at one point in the 1960's, the part of the United States now called the "Rust Belt" used to product greater than 60% (I think I'm being conservative here. I think the number might have been higher than this.) of the manufactured goods in the world. This region...

Great call! Can you share what it is that you saw in Silver that caused you to enter the position?

Back when the highest marginal rate was 92%, the bracket was at such a high income that a very small amount of people actually paid that rate....like only a few hundred. It was the real super wealthy who were paying the 92% rate (not that this made it right to confiscate their much income just...

She has herpies.

Technically this is true, but in practice you can game the situation. After the dot-com bust, I had a friend who went on unemployment for a very long time. He had previously been a Unix system administrator I think. My recollection is that it worked something like this: The rule was you...

There is a little hype. Undoubtedly, ballistic missiles will eventually make all surface ships obsolete. The US Navy is vulnerable to any type of swarm attack by low-value attackers. (The US Navy's own wargames had the fleet getting annihilated in a simulated attack by swarms of speed boats...

The biggest problem here, is that most of the cheap real-time data-sources, won't let you monitor that many symbols at the same time. If you only want to monitor a 100 or so, you can just use Interactive Brokers and connect to the api with C# or java to do what you want.

Could the real reason that facebook hasn't IPO'd yet be that Zukkerburg is waiting for all of his legal problems regarding his ownership share of Facebook to be settled first?

No one expects anyone to pay more taxes than they have to. The point here, is that in his campaign, John Kerry criticized American companies that legally use foreign jurisdictions to shelter themselves from taxation, calling them "Benedict Arnold companies", implying that it is morally wrong...

Wow, what a straight-forward explanation of wealth and money. I enjoyed that article. Thanks for posting it.

For the record, I like option 1...

In first class I can open up my 17" computer and get some work done. In coach, about the only productive thing I can do is read a book.
