Question about forex feeds

Hello all. I was wondering if anyone knows where live forex feeds actually originate. For example, where are all the individual Metatrader and site specific trading platforms actually getting their feeds from? Also, is it possible to purchase your own personal, live data feed from wherever the brokers get their feeds from?

Prices originate from the wholesale market.
That can be sourced from banks or wholesale brokers.
As for purchasing the data the wholesale broker will provide you raw data which is very expensive and only if you are eg quant a hedge fund type you only need this type of data.
