Making an iphone appp

Hi im making an iphone app for trading the stockmarket

Can someone please recommend me a datafeed that will not cost me lots of money per customer every month?

I was hoping to pay about 40 a month per customer for the feed with forex and some exchanges. At the momenet its looking like a lot more money.

I dont mind starting off with forex only though.

Any help would be great.

Thanks

Chris

Prorealtime are cheap for charting, maybe you can try them for raw data

You should be aware that if you are displaying any exchange's data that you will need to enter into a display licence with them.

The exact fees depend upon whether you are display live data, delayed data, end-of-day data or in some cases "next day" data.

Which exchanges and which timeframes did you have in mind?
