Paul Demers had a very nice presentation of his real time excel butterfly analyzer risk graph
I was wondering how difficult it would be for someone to build something similar ?
Also how much hard drive space does all that data collected take up ?
This a,most good enough if not even better than ONE or OV
I wonder if that would be for sale how much it would cost ?
status1, I think it will be pretty expensive as you have to by also Paul's time to set it up and customize for you.
To build it up is not _that_ hard*) just you need to know exactly what you want. Requires time...
As per being better than ONE/OV I'd say it depends.ONE/OV are good way to get feeling of new trade not so good for extensive back-testing. I cant force myself to sit in front of monitor and click for few hours straight, that's why I'm working on my system. As I said, it is not too hard*) just requires time. Especially when you build it for yourself you don't have to worry about whole GUI.
Try to get some data and start playing with Excel and VBA (youtube is your friend) - if you have time and if you want to go this way : )
*) I'm taking about simple data manipulation. If you want go into building/improving models it is different story and I'm not the one to talk to.
