Best execution venue for FX and CFDs. I have tested dozens of brokers, but no other venue can match the execution speed and spreads of LMAX Exchange. Also the fact that they are an Exchange and do not Trade against the clients, makes them my favorite venue for trading.
I have no experience in using their web platform, which seems very good. But I do have experience in using their MT4 platform (serviced by PrimeXM) for several EA's. That had worse results than e.g. AlpariUK, so be careful there.
I cannot say enough good things about LMAX when it comes to trustworthiness. They have been nothing but dependable and quick.
Their MT4 set up is very decent, never had an issue...already been trading with them for years.
Their spreads are tight on EURUSD, AUDUSD
They haven't adjusted their margin requirements in panic every time uncertainty looms (most brokers have gone nuts that last year with this)....last time I can recall was Bexit....for the rest, they've stayed put for years.
Their leverage is very meager in comparison to most retail friendly brokers...just 1:100...
You STILL have to go via a person via chat to transfer money from your MT4 to your web account....come on LMAX, it's 2017!!!
Their SWAP charges are the highest of ANY broker!!
So, would I recommend them....? It depends on the trading you do with them, day traders, short term traders should be OK, but if you have long term strategies, find another broker.
