AlumFx - does anyone have any experience with them?

I have opened an account with them a month ago using their promo (trading without commissions). I have traded EURUSD with the spread below 0.6 and my EA was/is crazy scalping with such conditions. I've made really decent profit and multiplied my initial depo, but now I'm a little worried about withdrawal..
Can anyone give their input/advice on:
- If someone had an experience with them, especially withdrawing money: how fast it is and are there any problems?
- Do they practice nullifying/not crediting profitable trades after the fact, as we seen with this guy who "lost" 19k recently in other thread?
- Or any other information regarding interfering with profitable trades/clients?

They are FCA broker and I understand what to expect, but recent posts and unusually good trades made we worry and suspicious.

Looking forward to hear what you think guys

well, I trade with them, trading conditions are good (spreads, execution speed), but other than that, usual broker, no problems with withdrawals (however I have withdrawn small sums) and haven't seen any abnormalities or red flags so far..

What amount are you going to withdraw?

This broker is regulated by FCA, but it is owned by Russian capital, they are quite small, I don't know if they behave in correct way

But doesn't FCA guarantee that we as traders can relax a bit?

It should. Mini-update: don't see anything unusual and withdrawal was made ok.

More than few thousand.
