I am currently trialling an EA to run my trading method automatically and I wonder if any bright spark amongst the members can tell me what sort of electricity bill I would have if I kept the computer on 24 hours a day? If some kind person would convert the amps, watts and volts into pounds and pence, it would be very helpful.

Any advice on how to set the computer up to do this in the most economical fashion would be greatly appreciated.

To calculate your costs use this formula:

((Watts x Hours Used) / 1000) x Cost per Kilowatt Hour = Cost to run

For example, let's say you have a big high-end computer with a gaming-level graphics card and an old CRT monitor, and you leave them on 24/7. That's about 330 watts x 24 hours x 365 days/yr = 2,890,800 watt-hours, or 2891 kilowatt-hours. If you're paying $0.14 per kWh, you're paying $405 a year to run your computer

Most "normal" PC's will use roughly 80Watts per hour, when functioning and not on sleep or standby.
Just substitute what your local council charges per Kilowatt Hour.

Thanks very much, westernforce, that's very helpful. Since the markets run Monday-Friday and my computer is a perfectly normal business level one with an LCD screen, I am reckoning the cost at about £2 p.w. for round figures.

If the EA can't cover that, plus the odd crust for me, it's not worth its salt anyway.

Thanks again.
