I am interested in writing a custom code that would draw real-time
ticker data, say from Yahoo Finance, and perform mathematical
calculations to make daytrading decisions. For example, the code
would
execute the following: "if the stock drops by 5% from the day's open
price, buy x number of shares, then sell if goes up by 3%". I'd like
to use this app. with a discount broker account (Zecco Trading or
SogoTrade).

More sophistication can be added later by gathering market data from
various online sources to make the trading decisions (such as taking
into account the change in the DJIA, VIX that day, the resistance
levels, etc.)


Since discount brokers do not offer APIs for this purpose, the custom
apllication will need to imitate the manual actions of buy and sell
(enter the price, number of shares, click on the buy button, etc.).
This is one way I can think of for placing the trades automatically
although there may be other ways I am not aware of.


I was wondering if anyone had suggestions on what programming
language
(s) would be most suitable for writing the application that I
described. I'd appreciate your comments.
