I trade via OANDA using the MetaTrade 4 platform they offer, which means there is no charge for data feeds, and I have no idea what people are talking about when they mention commissions in connection with Forex. I believe that outside of the spread, the only cost I incur comes from margin if I hold a position overnight (Swap?) which I almost never do as a day trader. The record pictured below is typical, where my total deductions after ten trades amounted to
-16¢, and if fact, two trades later (my 12th trade, not pictured) I received a Swap of
+20¢.

Since my lot size was only 0.05, I was making only a few bucks per trade. If I had been trading through my old broker, E*Trade, each transaction would have cost me $6.95, or $4.95 since I make more than 30 trades per quarter, so that it would not have even been worth it to trade at all!
To me, there is no best pair. There are some exotic pairs that I think are really BAD, and it seems to me that it takes a somewhat larger account balance to trade the Cable (Sterling/Pound) pairs, but other than that, I will trade any of the majors (i.e., AUDJPY, AUDUSD, EURGBP, EURJPY, EURUSD, GBPJPY, GBPUSD, NZDJPY, NZDUSD, USDCAD, USDCHF and USDJPY).
On second thought, often USDCAD and USDCHF do not travel a lot of distance, but USDCAD moves like CRAZY on news, so if you get in early going in the "right" direction, there are times when even these pairs can offer significant gains.
