Just to give you a small rundown. If you had the market data imported to Excel you would have a PowerShell script that analyze the tables with your important values. If the fluctuation is steady the PowerShell script places the machine in hibernate mode. With the scheduled tasks you can than have the machine run up at designated times triggering the script that monitors the values. Once one of the values causes an alarm trigger, such as a price fluctuating 10%, you can than have the script trigger an alarm that you have deemed fit.
Ok. Does that work with a ready made software or some windows function (mentioned above) too?
