Non-Broker Dependent LIVE Real Time Data Source for MT4?

Does anyone know of a GOOD Aggregate Live Real Time tick data source *or every 5 seconds*...that can be used live with MT4 independent from broker data?

I'm testing a multi currency price change strategy but because of minor price variations between brokers, it is producing different times of entries across different brokers.

I'd like to consolidate the data feed from a good online source of data so I can generate the same entry points and test.

I know I'm looking at 2 things here...

1. A good aggregate live data feed...preferably free.
2. Pulling that data from the website.
3. Importing that data live into MT4 (I believe there are some threads here on FF regarding this).

I'm on step 1 and 2 right now.

Anyone know of any good live FREE data sources that cover all the majors and major crosses?

Any suggestions?

If you download Mt4 or Mt5 from the official metatrader website, doesn't it use their feeds? non-broker dependant. That's what i always thought.
