What do you mean by "wholesale fills". Its a straight up central limit-order book, there is nothing more to see/know really.
Or do you want to see trading activity/T&S-data? It is published on Reuters only (ticker EURUSD.LMX for example) - unfortunately not available over api or fix...

I my opinion they are pretty good for G8 FX, but IB is better in some of the minors like MXN, CNH, RUB. And their index products need more marketmakers to be even remotely interesting.
Not so sure about that. How many worthwhile LPs are there really in FX. On Hotspot there are now only ~20 left, after they kicked all the useless ones with low fill ratios out.
Personally i am using lmax only nowadays. They got the top 10 FX banks, 4 other banks and a few HFTs on their...

Why do threads like this only ever pop up on FX boards? The futures/options/equities boards have their fair share of stupidity, but nothing on this order of magnitude..
Its what retail FX traders call "hedging". Being long and short in the same pair at the same time (and paying swaps and bid/ask-spread, and possibly commissions for the privilege). Apparently they do not understand that it nets out to zero exposure. I think it is very amusing.
Here is a real one:

Apparently one of their traders pushed the spot gold price down a few cents during the fixing procedure, to avoid having to pay out a digital option to one of their clients...
