So I can shuffle $1M between £ and $, costing £6/hour, and earning guaranteed money whenever the rate moves by more than 0.00003 in a half hour period?

Sounds open to abuse!

You can do it once or maybe a few times.

If you are majorly adversely selecting their liquidity provider, they will just shut you off.

It’s not an exchange.

Their overall risk to an individual account is a few 100, and very few accounts will try to do this.

It costs 6 quid to enter a reverse iron butterfly with like a 30m expiry on $1M of underlying.

I don’t know enough about forex to determine whether that’s a reasonable premium, but it seems like a pretty good deal at its face

They don't offer leverage.. and if you actually have £1m cash are you really going to break your balls for a couple of Great British Pounds?

You only pay the £6 if you complete the deal. If you cancel midway, it's free.

Oh - and it's £3.

3 quid per leg, 6 for the reverse iron butterfly position which is both legs

you can win literally dozens of pounds!

I don't have $1M so maybe I'm not an expert, but it looks like there are plenty of better (and safer) ways to earn money by investing your $1M on traditional investment.

I wouldn't like to be banned and lose access to my $1M (even temporary) but you do what you want with your millions.

Imagine if you buy apartments and rent them for thousands $. Haha, sounds open to abuse!

Save yourself the trouble. I’ll write you the contract myself. Just give me the million quid and I’ll pay you the £12 a day.

No need to actually move anything.

I'll do £13

"Standard delivery takes just a few days. And we’ve got instant delivery when you need it."

So you will tie up your 1MM for a day or more to earn a small few pounds? Surely you can do better with some other investment scheme.

Also, chances are instant delivery costs (much) more than 3 pounds.

Why would that be guaranteed? Do you have a magic formula that tells you exactly what the exchange rate is going to do at any given moment?

If so, can I see it?

If the rate moves in my favor, I complete the trade and earn money (minus the £6 fee).

If the rate moves in the opposite direction I cancel the trade and retry in half an hour.

That's fairly standard, even among banks. I have a bank account and account with their FX desk, when I need to do conversions. They give me a spot rate real close to what you'd "seen on google", but I have to close the offer within the hour or it's not valid anymore. It's a big european bank.
