Cabletrader which is a guy on ET who opened account with Oanda he is trading against Oanda so if your broker is a bucket shop like Onada you are on your own Cabletrader opened with Oanda because IB requires 10 k to open account
If you are trading bucket shop aka market maker yes. If you trade ECN model no, you are trading against a bank. Here's some reading for you http://www.forexfactory.com/showthread.php?t=7484
Hey Oanda isn't bad for a MM. They are the only MM I would trade with. Friends of mine have traded with them for over 6 months with very few problems.
The broker I would choose would definitely be MB Trading, especially since they are going to use the MetaTrader4 platform soon (they're still testing it). Once they are done testing, this would be the only MetaTrader broker I trust.
What's the big deal with MT4 anyway? Good charts, but horrible order entry. For that much every forex platform I have demoed is a dog compared to futures. So many clicks just to make a trade. As my friend said it's to their advantage to make it slow, more spread earned. MB seems legit but expensive.
Once you start getting familiar with MT4, it's a breeze....plus I use a lot of keyboard shortcuts. Since the spreads are so tight with MB Trading, I don't really notice the commission prices. I guess depending on the lot size you trade, the commission can be the cost of one pip, which you can make up in the tight spreads.
