Perl - neato!
At Yahoo I was using the CSV stuff. The perl method looks interesting. One negative with Yahoo! (maybe you know more than I) is that once the day is over you cannot retreive the detailed info any more. Said in a different way - if I pull up 5 symbols, I can then download the CSV for those 5 for the "day" (or last I suppose) of fixed fields. Those fields are no different than going to the specific stock and getting say 10days worth of history. The advantage of know this is - if my system crashes and I lose 5 days worth of information, I can then just "re-do" all stocks for say 5 days and boom everything is back up. If I rely on the "day-to-day" details - I am farked. Unless you know of a way to get the DETAILED stuff going back in time.
Yes the detailed is good - and yes I was looking at two things - an intraday model and an EOD model - I view them separately in my needs. ie Intraday is more "alert" data and EOD is more "report/scanning" data.
Do you know how to get Detailed after the day is over and everything is reset?
Yes a 52 week range - I can get that anytime summary or portfolio style - the Perl app seems to be a faster way of getting at specific fields. My wget method was (CSV excluded) to look for keystones and then rip accordingly. Once I setup a specific VIEW and rip accordingly, I can then get one or 200 stocks without fail. that perl app gets around bothering with the VIEW.
Technically I don't need a 52 week range, for example, if I have 52 weeks worth of data and just rebuild that reference. But yes, if I can use the perl app and get that every day, then that would save a bit of cpu time if I have to re-get the data.
The other bugaboo is that Yahoo adjusts ALL dates for Splits. That for me would trigger a reget of ALL data going back X years.
(Were you inferring you needed help for CBOE? In my other life I love programming and only charge $125/hr - minimum 1 hour for little jobs like that.. the high rate helps with the pain.. you know "Pain and Delight" .. posting here is the "delight" aspect of my life).
Again thanks for the URLS.. the fire has been stoked again and I love what I am seeing...
I was looking for some basic charting tools - I think I have the one that actually Yahoo! uses (data excluded) - complex stuff. To be honest, though, my big picture goal is to screen and then review the chart (and I suppose that is what most do). So charting myself isn't such a huge thing - Stockcharts is cost effective.
