I've got hold of lots of software for traders using Metatrader 4.
One in particular i've wrote myself :)
it's an info indicator - shows on the chart the swap rate long and short, the pip value per lot, the daily ranges, auto calculates the 2% rule and even gives the high and low for the day. I find it very useful.
If you would like a free copy of it and maybe some other stuff in the future then just send an email to forextraders 'at' getresponse.com sorry I cant give a link but the spambots pick em up like crazy.
