An other thing : Any of you ever traded some NASDAQ commodities ( energy for the most part )?
Didn't they just announce they're closing NLX? I'm sure energies won't be far behind given the already existing venues.
Tradator, one thing I think you should do is seriously consider what exchanges you need, what exchanges you want, and what exchanges are a nice to have. Make a literal table sorted by that and then focus on FCMs and platforms which primarily cover the need/want.
At the end of the day do you really need the LME headache or ability to trade on BMF? Some of these exchanges sound cool but when you actually look at the product offerings or liquidity they're not always that great.
