FX:
If you want to backtest interbank FX, then it's relatively pointless to use any data that is different from
that of your broker's pool since you won't get other fills anyway. Besides, depending on the pool size,
several millions of ticks per day e.g. for EURUSD will inflate your data pool but not deliver any added value.
A plus for FX is order amount, i.e. you can start with chicken feed.

Currency futures:
The advantage of currency futures is centralized and standardized trading via exchanges. Data suppliers are the
exchanges. CME is most liquid, Eurex a distant second. So any reliable (tick by tick) CME futures data stream will be
adequate for backtesting and trading. The price that you pay for centralization and reliability is standard contract
size which can be a problem for small accounts (micros aside which offer lower liquidity combined with higher
relative commissions).
