you mean excel,right? if so-yes. excel is very flexible and could be the only tool you need. specially when combined with knowledge of VBA http://en.wikipedia.org/wiki/Visual_Basic_for_Applications
Ha! Yes my bad that what I meant!, I have been tinkering around with VBA for the last week, seems like the only limitation with it is ones imagination. At the moment I am manually going from chart to chart in search of my buy signals which is very time consuming, hence the reason I would love to be able to just enter data into excel which in turn would change a stock to red or green based on whether the "entry" signal has been triggered or not.
yes, most likely you will need VBA for that . and if you don't know the language-it will be hard. add complexity of the 'signal' + database,where all information was stored. chart that you see is just a graphical representation of this data. if it's online-this mean data is stored on their side. if you want to run scan from your PC-the data have to be on it too.
Yes im trading not intra day, just trend/swing type trading. So end of the day data is good for me. I currently use yahoo finance stock historical data, from which I calculate my stops by calculating true range/ATR with excel, I use VBA to customize my own formulas to save time.
you can try to record a macro or something. do it for one ticker using maybe a web query(i'm not an expert in excel and rarely using it) and then -put it in some sort of loop,where all you have to do is to change that ticker in the query http://www.experiglot.com/2011/10/1...s-in-excel-with-macros-or-any-other-web-data/ google something like yahoo stock data excel macro. there is also big yahoo group dedicated to this particular direction-excel and trading. somebody probably done this already 100 times or so. all you need is to find it and modify to your needs.
I have the same thing. I solved it by modifying a yahoo from the internet. I still dont know any VBA. Problem is data is updated at 4:15. So you have to input data from 3,45, then change the close time, OHL is accurate, but C is 15 minutes off, unfortunately.

that defeats the purpose of making money though. plus I would have to modify the VBA again... and im too lazy.
