I don't think there is a tax-free country, especially for the capital gain. They should pay for the road and military by tax. But I heard that many country like US charge about >30% for the highest tax bracket in 1040. However, in Singapore they charge as low as 20%. So, what we need...

If someone has already experience in API for a particular brokerage company, he can be a good candidate for this project Also I hope he had VB experience too, for easy conversion. Actually the previous VB work for dynamic (intraday) data reception was written by my friend with pay, since I...

1) Personally I have experience in R and MATLAB(similar to Python) many years. But no experience in JS and C. That is only reason. 2 )I do NOT understand the "memory" and "DB". Please explain the difference precisely for me. 3) Of course, 3-dimensional array with dimension c(2000, 4...

In us dollar or other currency? The three program is running good in Excel VBA now, and like to change its language from Excel to API with R. I can provide the VBA source code, if needed, that was running perfectly for more than five years.

Hey [pgo] You should tell us which country will be that kind of tax system.

It was a huge amount at that time. I heard the father of Buffet was rich too. Probably congressman. But note that the initial seed money is NOT important in this column. For example, suppose A has annual 18% and B has annual 20% (ONLY 2% difference) over 48 years, A makes 1.18^48 =...

For example, if we start with 10K at the age of 30 After 45 years later(at the age of 75), 6000 times of 10K might be the best result (in the whole world), if he shows annual 20% return (after brokerage and tax).

When I see the >45 years record by Warren Buffet at http://www.berkshirehathaway.com/letters/2013ltr.pdf There is an important number in lower right corner. Over the 45 years, 1) SnP500 increase roughly 10 percent annually 2) Birkshire investment show annual 20% 3) Therefore...

I think we do NOT need as high level as API. Probably R or Python may give us a few line (without connection to company login), using program connection from google or yahoo quote. Anyone have experience with R? Please direct me a few line, possible with library() and require() in R...

Thanks for moving. I did NOT aware it.

Let me give you an hypothetical situation. I am a newbie in NYSE with short English. My understanding of the "contingent"order is as follows. Suppose current price of MSFT is $30. If I order contingent, it means that if the MSFT hits $28 then contingent is (WILL) changed to "regular"...

To [eusdaiki] Personally I spent years in R but I am new to Python so that I download the Python today. Appreciated if you find any intraday in google, for use of R. I am ashamed to have not enough knowledge for searching it.

Thanks to the two helpful comments. To [vicirek] There are three places that I posted at the same time. It is because I did NOT know the appropriate place at the beginning / Sorry if you are confused.
