Just a quick demo of our Forex Calculator App. It's available on the iTunes store. http://apple.co/1PfD2wp We've recently updated the App for IOS 8, and we've also added support for gold and silver. You'll see the position size, pip value and margin calculators in action. It also has a trade simulator and support for multiple base currencies plus much more. Thank you to our customers who have provided valuable feedback and suggestions. If you have any questions, feel free to contact us via the contacts page on our website: http://www.forexprofitcalculator.net/
