Dumb question but can you set your computer to beep every 5 minutes? if so, how? I trade off of 5 min. charts and the close of the bar is usually when i decide to take a trade and I miss so many because I'm not paying attention to the screen, loose track of time. If not I'm sure there's some type of clock or something i can pick up but I work in an office so I don't want to use the snooze on an alarm cause it will affect others around me.
