Hi N,
Did try to PM you back, but it says your account settings don't allow you to receive PMs... Anyway, I'll answer you questions briefly here:
- LMAX are one of the few places retail participants can get access to institutional-quality spot FX. As such, I highly recommend.
- I use them for FX trading, and have had zero problems. Tbh they have exceeded my expectations.
- You're fine to scalp with them. They operate an FX MTF (if you're newer to this, it's similar to an exchange-style ECN). Advantages include: v robust platform (I've never had the platform crash), extremely fast execution (avg 3ms), v low spreads on FX pairs (avg less than 0.3 on EUR/USD) etc. Obviously due to the MTF model, the broker doesn't & can't trade against you, and they don't allow 'last look' trade rejections from LPs.
Be prepared to hear criticism of them on forums like this. Many bucket-shops etc spend a lot of time on forums trying to persuade clients not to trade with professional brokers. Anyway, your choice. Good luck.
