Please forgive me for (possible) mis-insert for the 3 pictures. This is my first time. Many years I am familiar to R and Python. Although those 3 were written in Excel by my friend, I am NOT used to Excel and VB.

Here are outline of Excel program working fine now. Unlike in US, many still use Excel in out of US. Please note that some letters are not English, but it not a problem at all. (Attached in Pic 1) Pic1 shows daily close for 100 days, for personal watch list (roughly 200 stocks). This is...

OCLC+volume are fine for me.

Hi, I am used to use the yahoo.com, R, and Python, etc. I wonder how to retrieve the above data, with dimension of 1200 rows and 500 columns. In case the computer capacity is over, it is fine to reduce the row and columns. Thanks in advance.

Instead of great depression, I heard it is GREATER depression.

Appreciated for the replies.

I understood that IB and TradeKing were the best commission, under $5 per trade. But I heard that Tradier is less than $3.5, as shown in https://brokerage.tradier.com/pricing ***************************************** Is this THE MARKET BEST? PS) Please consider ONLY equity, since I NEVER...

Dear- I heard we can download historical daily close for certain stocks, directly to R language. For example, if in R command we type such as xxx(MSFT, 19900101, 20101231) then OCLC is shown in R screen. Is there any easy manual to start with, for a beginner?

Dear- I used to use yahoo.com to retrieve old data, such as DowJones in 1929. But recently they do NOT provide old data, if I am correct. Where can I find old data, such as big drop data in 1929 and 1987 ? Thanks.

Would you please tell me the link where I can install? Ubuntu or Mint, whatever you recommend? Also, anyone have trouble to use the web trading system, such as Etrade, Scottrade, .... And how about the API use in IB and TradeKing under Linux?

To [Volpunter] Actually I am equity trader with more than 5 years experience. But unfortunately I have never trade or even never open any account in future/option/forex. For the equity, one charge brokerage for each 100 share and the other charges for number of execution.

Please correct me if the above is wrong or over-stated.

I heard that the two company (IB and TradeKing) have considerably large volume of API users. Anyone have used those two APIs together so that one can compare the two? ********************************************************* Basically API does NOT depend on specific language so that we can...

I hope I were in your local ares so that we can talk face-to-face. Actually I am not used to NYSE API although I have more than 5 years of automated trading experence in other country than NYSE. I can hardly understand the "trigger" and "market and limit" I almost never bought any stock at...

1) data subscription (around 400 equity) 2) API order, e.g. 100 equity orders together

Main reason to visit there is as follows. If someone helps me for API programming from out of state, it is NOT easy to communicate. So in Wall street it might be possible to see each other at a coffee shop to talk about what I need many times. I can think about roughly $1K for API...

Dear- I have a few years of trading experience, in equity (never in future/option). Although I am a frequent flier in many cities, I never been in Wall Street after I start trading. I can make a chance to stop in NYC next months and spend a few days in(near?) Wall Street with my personal...

Possibly IB insured IB by itself, so small money is accumulated everyday for potential big loss. It is important that many traders are addicted, such as by their proprietory API and other reason(s). They know that it is VERY hard to change broker.

So, in my understanding as a NYSE newbie, the exposure fee in IB is ONLY for future/option, NOT for all-cash buy equity. Isn't it? I heard, in some options, traders can lose MORE than his seed cash in investment. Probably the exposure fee is premium for insurance for future damage in IB...

Although I have little knowledge on option and NYSE, it may implies "Since hurricane is coming, IB is recently asking more insurance premium for possible house damage" , which means that if you NOT want to pay insurance you are free to go to OTHER BROKER. But I guess many are addicted to IB...
