[Jprogramming] j - opentick

[j.language at antelecom.net]

My personal use is to download raw data for a stock for a
specific timeframe.

I after capturing the data to a file, I will do post
analysis on the data.

I have decided to use the socket support that is part of the
j release to empliment a client application in J that allows
me to communicate with opentick.

take care!
