Paying for access to a live exchange rate feed can serve you in many ways in your forex trading, and depending on your devotion you can even use it in your own software programs.

If you are either a programmer yourself or know how to outsource such tasks, you could use this data feed to build your own custom software applications and trading indicators.

Another popular use for such a data feed is to incorporate the live exchange rates into a website. This type of site is typically called a portal site and it could become a useful resource for yourself as well as other traders.

If you are truly a clever person, you could program desktop widgets that incorporate this data. Seriously devoted people will sometimes program their own software just so that they can have it exactly as they want, not to mention having an unfair advantage over any competition.
