Is there an indicator that charts balance/equity?

Can anyone point me to an indicator/expert that actually charts the balance of an account in real time.

basically i need something to record an account with a hedge set up in it.

i have buy 1 lot of EURUSD and sell 1 lot of GBPUSD in an indicator account and the profit will fluctuate + and - because of the pairs correlation.

I want to record this to find the extreems that they reach i.e. the maximum divergence between the two pairs.

I hope this makes sense

Thanks Paul

This may do what you want, but it would be easiest to just look at the trade terminal.

dear sir
i tried your indicator but it does not show not real time
could you please modify it

I don't have what you are asking for but I find this indicator useful in evaluating spreads.
